The joints and muscles of the body function most efficiently when they are in physical balance or equilibrium. Our feet are the foundation of our body. They are made up of three arches (like a bridge) creating a tripod-like structure (see picture below).

This is an exceptionally clever design as it provides strength, stability and shock absorption all in one. However our modern urban life puts untold strains on our feet, with unsuitable footwear, hard flat surfaces and poor body conditioning. Foot problems are now occurring in pandemic proportions (at age of 20 up to 80%, at age of 40 ~100%). Any compromise to one of the three arches of the foot will increase stress on the other two, thus starting a kinetic chain reaction that can spread via knees, hips, pelvis and the spine throughout our body (see diagram below).

A scientific scientific double blind study measuring the neuro-physiological stress reaction of the body during gait, has shown that wearing standard flat-sole flip flops or walkingstress. barefoot on a recorded flat surface significant neurophysiological Results viaproduces a digital dynamometer

 

(microREM2) showed negative kinematic chain reactions through the body,, after only a 10 metre walk. Long-term exposure to these negative body effects can lead to many familiar medical conditions such as: Joint degeneration, foot & ankle pain, plantar fascitis, achilles tendonitis, heel pain, mortons neuroma, shin splints, compartmental syndrome, knee pain, patellar tracking syndrome, ilio-tibial band syndrome, hip and pelvic pain and low back pain to name just a few few.. equilibras™ in contrast evoked NO neuro-physiological stress reaction

during the study. To the contrary, they consistently produced a neurophysiological stimulation. These results are achieved due to equilibras™ unique design, providing the best possible support normally not offered by a flat sole. The invisible inbuilt orthotic contour is able to maintain FOOT ALIGNMENT and CONTROL, whilst the unique bi-phase shock absorption layers are providing maximum FORCE DISSIPATION during gait. The outcome is an innovative flat-soled flip flop that can help prevent the occurrence of foot problems, as well as give our bodies protection and relief from the effects of some pre-existing foot conditions and also eliminate adverse neurophysiological stress caused by poor foot biomechanics during gait. equilibras™ - helping to maintain balance in our bodies. Upright walking is often taken for granted. Our feet create the foundation for our body. When the foot is unstable the remainder of the body is unstable. Normal foot function allows us to walk efficiently.

Normal Foot Function In 1953 Hicks described bone and soft tissue function of the foot. He used pointers and rods to demonstrate how a joint moves. Motion within a number of joints of the foot is tri-planar in that a joint can move within all three-body planes (sagital, transverse and frontal). In 1977 Root et al also described normal and abnormal foot function. Pronation and supination of the foot is a normal and required motion for effective ambulation. When the degree rate of pronation and or supination are excessive then the foot can noor longer function appropriatel appropriately. y.

 

For proper foot function and maintenance of the foot structure, our feet should be regularly exposed to uneven ground of differe different nt densities. This maintains much needed afferent stimulation of the brain creating high quality brain mapping. Due to our current (urban) lifestyles our feet are seriously understimulated. Furthermore being for prolonged periods of time on flat surfaces in shoes s hoes over-stresses our “loose” feet in the midstance.

Effects of Abnormal Foot Function When the foot is excessively pronated (lower arch) the lower leg internally rotates which in turn creates an abnormal pull on the patella (kneecap). This can create knee pain. The femur is then forced to internally rotate which in turn cause the pelvis to tilt forward, increasing pressure on the lower spine. The adverse forces created in the lumbar area then force the spine to compensate, sometimes resulting in thoracic and cervical pain and mal-alignment. Conversely when the foot is excessively supinated (high arch) the lower leg and femur externally rotate. This reduces the ability of the foot and limb to absorb shock and increases lateral instability.

Corrective Devices & Shoes Excessive pronation of the foot is a common problem that affects a large number of people. Orthoses or "orthotics" as they are commonly known as, provide an ability to correct the pronated foot whilst in the shoe. Orthoses have been shown to reduce excessive pronation thus reducing the abnormal rotation/motion about the lower leg, femur femur,, pelvis and spine. The degree of control within the orthosis determines the degree of correction. A contour, contour, which engages the natural mid-foot locking also at mid stance, will further add stability with reduced stress on support structures of the foot. However orthotic devices should not ignore a further important quality of foot arches namely shock absorption. The arch support should therefore neither be too high nor too rigid as it will otherwise negate the benefits of alignment achieved. firmtohigh arch support(very will much not allow natural support tissues of theAfoot be conditioned like the a firm neck or

 

low back brace). Thus it creates a dependenc dependency, y, which will only worsen foot stability in a long run. Our philosophy also is to provide minimalist support to all three foot arches rather than to focus on vigorous support of the medial arch to the detriment of the synchronous balance of all three arches. The effectiveness of this approach appears to be supported by the results of the aforementioned studies done with the digital Dynamometer and functional muscle testing.

Solution Orthoses are difficult to fit to a sandal and impossible to fit to a so-called thong, flip-flop or jandal. Our product with its invisible inbuilt orthotic support has addressed this problem providing the wearer with a high degree of correction and stability during usage whilst still maintaining the necessary shock absorption qualities. In short our e-flips™ and e-beds™ provide: • • •

General Requirements As we know the joints and muscles of the body function most efficiently when they are in physical balance or equilibrium. Our feet are the foundation of our body. Now imagine the full body weight being balanced continuously over our relatively small feet. Apart from the delicate balancing act of our nervous system, this requires a very strong foot structure, flexible enough to adjust to any surface changes and body movements, yet at the same time rigid enough to maintain stability and control so as not to overexert supportive tissues such as joints, ligaments, tendons and muscles (1). Furthermore the kinetic energy created by the gravitational forces of the body (3-5 g-forces during regular walking) need to be continuously buffered (dissipated) (dissipated) in order to avoid tissue damage to the feet or any

 

structures above along the kinetic chain of the human musculoskeletal system. So how do the feet do that? In simple terms they are made up of three arches (like bridges) creating a tripod-like structure (1)[chart (1)[chart 1] This is an exceptionally clever design as it provides control, stability and shock absorption all in one. The design (tripod through arches) (chart 1) and the orientation of the foot  joints allow for clever CONTROL CONTROL oonn most kind of surfaces. The tripod design also provides for STABILITY even on uneven surfaces. This is further enhanced by various locking mechanisms (e.g. windlass locking mechanism, mid-foot locking (15,16,90-1098)) that come to bear particularly during critical phases such as the push off phase where the weight is shifted onto the fore foot and loaded up in order to propel the bodyweight forward. In order to protect the feet from the impact of our bodyweight obviously the full spectrum of joints particularly of the lower extremities are engaged (2). However the tripod structure made up of the three arches in the foot again is very well suited. Like springs the arches can dissipate (SHOCK ABSORB) any remaining forces being transferred through the feet.

Status Quo When looking at the incidence of current foot problems, one cannot help but be gravely concerned. Some groups (Footlevelers)(3) quote the incidence of foot problems at 80% by the age of 20 and even worse at 100% by the age of 40. This begs the question why? As we know our modern urban life puts untold strains on our feet, with unsuitable footwear, footwear, hard flat surfaces and poor body conditioning. How can this cause such a pandemic in foot disturbances? Let us examine a few points a bit closer:

It has not been that long since humans (especially urban)started to live predominantly on flat hard surfaces. What does that mean for our feet? For a start most surfacestoare shock absorption capabilities thevery limit.hard Ourwhich archesstretches thereforeour start to feel the

 

strain. Remember the average person in the "lazy" western world still takes about 5,000 steps a day. Now one might argue that most people do wear shoes, which tend to provide some shock absorption. That is true, however they tend to have a rather simple and flat insole. (If there is an internal contour it's usually just a mild medial arch elevation. In high heels the insole is still rather simple and the sole under the front foot is usually so thin as not to provide any significant shock absorption). This brings us to the next more sinister problem that has its seat all the way up in our brain and has to do with brain mapping and brain plasticity (4-12). As research discovered, the brain is much more malleable even in adult life then was thought. This means the brain will constantly adapt to the environment. One way of doing that for instance in the case of our feet is, that it will constantly update the brain map (picture of a foot in the brain) (chart 4) according to its use or stimulation. For instance since most of us use our little toes largely in unison the brain map that controls movement of our toes (motor map) becomes very undifferentiated (low resolution picture) resulting in an inability of the brain to move them individuall individually. y. Likewise as the afferent stimulation of the foot sole (messages from foot sole to brain) become simple due to exposure to constant flat surfaces, the corresponding brain map simplifies. This then will lead over time to a loss of foot arch integrity and a lack of fine motor control of the foot by the brain. Add to this scenario the current trend of little physical activities and remembering that brain conditioning requires regular stimulation, we can see that we now have a recipe for the current foot problem pandemic.

e-bed™ characteristics Therefore our aim has been to create a foot bed, which has all the characteristics required to combat this current trend of foot deterioration by providing a stable, controlled platform for the foot with adequate protective shock absorption (neither too soft nor too hard) and appropriate

 

stimulation for a high resolution brain mapping as well as sufficient softness to allow proper windlass locking mechanism (90-108). All these qualities have been packaged invisibly into a thin flat sole. This foot-bed includes Pronation and Supination support via an invisible in-built triple arch with rear foot control, mid tarsal locking and dual action shock absorption. How did we do this and what makes this sole different from other orthotic devises? 1. The major difference difference to all other similar devices is that our footbed is flat, ie. it has no visible contour – This has various advantages. Aesthetically when used in an open shoe such as a flip- flop (eflip by equilibras™) ,it can look like the most popular flip-flops to date without a visible contour. ◦

Functionally the contour layerabsorption with a softer upper layer it createsbyancovering upper dispersive shock action perfect for the arches of the foot (13). The flat upper layer also graduates the impact on the firmer contoured layer underneath creating a similar s imilar effect to walking say on firm grass with harder densities in the soil. The main difference being that the higher densities are positioned strategically to achieve maximum control and sstabilit tability. y. This then provides for a high degree of sensory stimulation maintaining a detailed brain map whilst allowing for smoother

gait A flat flatcontrol. upper sole also has the advantage of reducing blisters and sores thus is easy to get accustomed to. This is a very important property especially in cases of diabetes or for soldiers. 2.Many contoured devices whether custom made or generic focus predominantly on alignment and therefore use mostly just a significantly high medial arch support. Occasionally we see a rearfoot controlled heel slant and/or a small lateral arch support, rarely a transverse (anterior) arch support. The problem with this approach is that whilst alignment is temporarily achieved it also ◦

creates instability to lack of mid locking paired mechanism. with interference of thedue natural medial archfoot shock absorption Some researchers (Dudly More) also argue that this will eventually

 

lead to muscle atrophy and eventually the loss of the arch structure. It also lacks the necessary contour relief needed for proper brain mapping and thus maintenance of healthy foot structure. 3. In order to impose its specific contour, contour, our bottom layer is much firmer then the top layer. Being a generic device it aims at stabilizing excessive pronation as well as supination. It also aims at giving improved foot stability through the intrinsic mid-foot locking mechanism (calcaneo-cuboid joint)(15,16 joint)(15,16), ), not only during the push off stance but also during the mid stance. This calls for an explanation - when walking BAREFEET on uneven ground the foot needs to be flexible in order to adjust to the ground. This however is not required whilst wearing shoes on a flat firm surface. It is therefore more desirable to maintain stability by activating the locking mechanism during mid-stance. This will minimize the stress particularly on the musculo-skeletal system and joints of the foot. The compressible make-up of this layer further adds standard vertical shock absorption (see dispersive shock absorption of top layer) The chosen density of the polyurethane material also acts in the same manner as industrial antifatigue matting, by greatly reducing fatigue (up to 50%). The characteristics of our footbed are therefore as follows: •

•

•

•

The rearfoot control consists of a medial to lateral slope placing the heel into a slight inversion (supination) assisting in the support of pronation (14) as well as the mid-foot locking mechanism (15,16,27). The medial arch contour obviously assists in preventing excessive pronation whilst still allowing for adequate shock absorption through that arch (especially whilst paired with a softer upper layer it creates the natural dispersive shock absorption action). Note that this arch contour is designed to stimulate arch proprioception and thus maintain the natural arch of the foot rather then support it. The misconception of support actually will lead to a gradual deterioration of the arch structure due to the lack of engagement of natural foot support structures as well as understimulated sensory afferentiation (4-12). The lateral arch rises early just past the calcaneum under the cuboid. The pressure created by this elevation initiates the mid foot locking, (15,16) further assisted by the rear foot control. Even though the majority of adults in our society appear to have lost their lateral arch, the maintained ridge still acts as an aid for shock

•

absorption and an important sensory stimulation for the lateral foot structures. It needs to be remembered that this arch is the first one to be activated during normal casual gait (13) Furthermore the elongated lateral ridge of our foot bed also counteracts supination distortions. A last small elevation anterior to the medial arch gives stimulation to the transverse (anterior) of thetofoot. is notproprioceptive big enough to create discomfort but justarch enough elicitItsome stimulation for brain mapping. Overall the two layers are soft enough to allow for proper windlass locking mechanism (91-109) and the combined densities of polyurethane act like industrial anti-fatigue mats.

research/comparison When we analysed the data from our double blind studies of neurophysiological stress response comparing walking barefoot vs walking on ordinary flip-flops vs walking on e-flips™ (17,18)(New Flat-Sole Orthotic Flip-Flop vs Standard Flat-Sole Flip-F Flip-Flop) lop) it showed that not only did e-flips™ out perform the other two categories but to our surprise they

 

even did better than the control group which was tested at rest! This is quite remarkable and we realised we were onto something special here. Whilst we have not been able to explain with confidence this outcome it sounds plausible that the rich and clever neurological stimulation of the foot-sole by our footbed is producing a very beneficial afferentiation into the nervous system which can create a detailed brain map(4, 24, 25)(chart 4).Most likely the contribute above-mentioned (e-bed™ CHARACTERISTI CHARACTERISTICS) CS) antifatigue properties to this effect as well (42-50). We also know from studies with orthotics of similar characteristics to ours, that foot proprioception, pelvic rotation and stride length all improve. Remembering that the entire body acts as a kinetic chain network (2,13,14,17-23, 28-37, 40, 41) we know that any distortions from the ground up need to be compensated for for,, thus requiring further effort and dexterity. This exposes us to a higher risk of injury, fatigue and poorer performance. From our experience we now postulate at least four key areas that need to be satisfied by a footbed in order to avoid detrimental neurophysiological stress reactions by the body – these are: ALIGNMENT, STABILITY (CONTROL), APPROPRIATE SHOCK ABSORPTION and SENSORY AFFERENTIATION (BRAIN MAPPING). It is interesting to note that all four categories need to be addressed in order to get the best possible results and avoid neurophysiological compensations (17, 18). For instance a good supportive contour without adequate shock •

absorption create a neurophysiologic neurophysiological stressinhibition. reaction during locomotionwill causing generalised transient al muscle This will then over time lead to compensatory biomechanical misalignments anywhere along the body's kinetic chain. On the other hand a soft footbed without stability and alignment will create the same neurophysiological stress reaction through the resulting amplification of existing foot distortions. Also some researchers (Dudly More) argue that exaggerated shock absorption (such as in many new expensive running shoes) can create proprioceptive misinformation misinformation thus leading to heavier and modified running fatigue. styles causing higher risk of injuries as well as earlier

 

Any of those scenarios will ultimately lead to a distorted or inadequate brain mapping with all its future implications. Many if not most shoe products only deal with some of these features! As we now understand this is a significant shortcoming, and if inadequacies are maintained over prolonged periods of time they can through compensatory mechanisms lead to substantial health issues (19 - 23). It should also be mentioned that disturbing the bodies' kinetic chain (2,13,14,17-23,28-37,40,41) (2,13,14,17-23,28-37,40 ,41) might not be as benign as expected. Any of these changes if maintained can greatly affect existing injuries or weaknesses further up the body (29,34-40). Particularly if affecting the nervous system for instance through subtle functional disturbance of the vertebral column, the resulting effects can range from mechanical over organic to neurophysiological problems (see chart 3). Our research also suggests that proper footbeds not only have a role in injury prevention for all ages, genders and activity levels, but they also aid in enhancing body performance, be it during every day activities as well as during sport. When doing an extensive literature search on the subject of orthotic foot devices and their impact on various health issues it has been noted that in many areas studies have been rather inconclusive or often unsubstantiated. Could it be possible that many products tested did not offer the full spectrum of requirements discussed above in order to yield clearer outcomes?

Increased productivity in industry

 

The damage caused to our bodies from prolonged standing is staggering as it rivals other serious diseases such as cancer, stroke or heart failure. Current research (42-50) has shown that anti-fatigue matting (as in e-beds) can reduce fatigue in 100% of cases by as much as 50%. These are astonishing figures and have a major impact on diminishing this damage to the body and thus increasing productivity and profits at work (44-46). Workers that are tired or in pain become a liability at their work place in many ways: Costly mistakes happen from diminished mentalacuity mentalacuity,, dexterity and physical agility. Reduced productivity and quality due to decreased attention to detail. Increased injury rates Increased absenteeism Decreased employer morale A recent recent U.S. study found that common pain conditions (back pain, arthritis, and musculoskeletal disorders) among active workers cost approximately $61.2 billion per year in lost productivit productivity. y. This equates roughly to 5.5 hours loss of productivity per week per worker worker.. Considering the low cost and longevity of e-beds™against a loss of almost 1 day per week per worker it becomes an economic "non-brainer "non-brainer"…the "…the money saved is staggering. •

•

• • •

Many products have since moved into this market niche. These economic realities have in many companies around the world forced anti-fatigue matting to become a standard requirement for their workforce with the following results: 1.Reduced fatigue and resulting damage to feet, legs back and neck. 2.Decreased venous pooling in lower limbs (leading to circulatory congestion and complications) resulting in lower workload of the cardiovascular system (heart & circulatory system). 3.Retention of better ability to perform routine tasks. 4. Dramatic results especially from the the third and fourth hour of standing. 5.Decreased musculo skeletal disorders (MSD) and decreased neurogenic fatigue problems (NFP) such as headaches, visual fatigue and concentration difficu difficulties. lties. 6.Better work force moral 7. Less absentee absenteeism ism

 

A good anti-fatigue anti-fatigue mat does essentially 3 things: it insulates against temperature extremes, it absorbs shocks to the body and it creates subtle leg movements preventing blood pooling and myospasm in the lower extremities. However it does NOT replace proper footwear footwear.. •

e-beds™ go a lot further: their bilaminated polyurethane construction has the same qualities as good anti-fatigue matting (reducing fatigu fatiguee by as much as 50%) (42-50), but in addition they also provide all the qualities of a top orthotic foot bed, namely:

•

Proprioceptive stimulation (support) and alignment (via the firmer bottom contour) Control via engaging the natural mid-foot locking mechanism (15,16) resulting in lower biomechanical stress of the foot support tissues. This also includes characteristics encouraging proper windlass (and reversed windlass) locking mechanism (90-108) Proper sensory afferentiation afferentiation for quality brain mapping, which will lead to superior fine motor control and combat structural foot deterioration. Protection against temperature extremes Water resistant Anti-bacterial,, fungicidal Anti-bacterial As a result they significantly decrease in MSD and NFP, which is a major factor not only in productivity but also profitability, profitability, as sick days and the associated massive costs to employers are greatly reduced! (44-46). They are also cost effective and since inbuilt in the shoes they are conveniently mobile anywhere anytime. •

•

• • •

All these factors considered, e-beds™ are the best solution for industry available to date.

Increase Increa se Performance in sports Much has been written in support s upport of orthotic devices and sport. Foot orthotic devices are used in injury prevention, injury management as well as performance enhancement (17,18, 30-43, 47-49, 57-64). Wi With th the increased commercialisation of sport, the above factors have become essential in the management regime of athletes. Our extensive experience

 

with elite professional athletes over the last 25 years certainly supports this view.. There appears to be however a few discrepancies in the approach of view therapeutic footbeds: Firstly when should orthotic footbeds be used? Secondly what kind of footbeds should be used? From all the evidence presented in this or document so far it appears obvious that every serious athlete, professional not, should take advantage of orthotic devices. - Why? – To rrecapitulate ecapitulate proper orthotic devices can support existing injuries or biomechanical distortions, help prevent negative kinetic chain reactions and their resulting injuries, can delay the onset of fatigue and last but not least can also improve performance by improving proprioception, proprioception, fine motor control and range of motion (30-50). Therefore it makes no sense, as often practiced, to prescribe them only when dealing with an existing injur injury. y. However an orthotic device needs to contain all the characteristics (see e-bed™ characteristics) to be able to achieve all the claims made above. Here is where in our experience many devices fall short. – So what type of footbeds should be used? – Let's look firstly at the rigid, semi-rigid vs soft orthotic devices. There is growing evidence now that orthotic devices should preferably (with a few exceptions) be of a soft nature. Three points appear crucial in this view: Only devices with appropriate shock absorption can prevent NSR (neurophysiological (neurophysiologi cal stress reactions). As we know NSR cause significant muscle inhibitions throughout the body leading to poorer performance and higher risk of injuries or injury aggravations (2,13,14,17-23, 28-37, 40, 41). Appropriate shock absorption is also necessary to combat fatigue (4250), which can overload the cardiovascular system and cause poor performance or training results. Many scientists are also beginning to recognise that stimulation rather than support of the arches of the foot is required for lasting effects. This appears mostly to be borne from the observation that supported arches cannot act naturall naturally, y, namely dissipate forces according to their design. This will then cause the support tissues of the feet to atrophy or deteriorate due to understimulatio understimulationn (4-12, 51- 54). The next question relates to custom made versus generic supports. Most studies performed on the subject so far are inconclusive (53-55, 64), which then begs the question why spend much more money on a custom made device if a generic device can yield equivalent results •

•

•

 

and comfort. This debate is further clouded by the fact that many custom made devices are of a more rigid nature and do not necessarily posses all the pertinent requirements (see four core qualities – e-bed™ characteristics) in order to achieve acceptable results for an athlete. The e-bed™ again ticks all the boxes. It is of a soft nature with superior dual action shock absorption. It contains the four coreasqualities (and more) needed to minimise NSR, NFP andallMSD as well delay fatigue and improve performance. It protects from temperature extremes, has antibacterial and fungicidal properties and is cost effective and convenient when inbuilt into your sports shoe.

Police / Armed Forces The men and women of the Ar Armed med Forces and Police Corps have always been subject to tremendous physical strains. In the past flat feet (pes planus) and extreme high insteps (pes cavus) were rejected in the service. Twoo factors have since changed these requirements in many armies around Tw the world: 1) The incidence of partially or completely flat feet has dramatically risen even in the last few decades to the point where many people consider it normal not to have transverse (anterior) or lateral arches. 2) Many Armed Forces and Police Forces are experiencing low recruitment rates and are thus lowering their eligibility requirements. This has meant that many people with unsuitable foot conditions are now being subjected to serious long-term problems or have to drop out due to persistent foot disorders. Few people on earth put their feet through more than a soldier does. Whether it is marching mile after mile carrying heavy gear, or manoeuvres through all types of terrain and temperatures, a soldier's feet must function at a high level in order for them to be successful. Police personnel too spend long hours on asphalt or other hard flat surfaces, wearing heavy belts loaded with equipment. These conditions place untold strains on these people's feet resulting in: Poor performance Increased dropout Higher rates of MSD (musculo skeletal disorders) and NFP (neurogenic fatigue problems) • •

•

 

Lower troop morale Obviously adequate physical conditioning and correct footwear are a must (65). As far as the footwear is concerned this is not as easy as it sounds as changing conditions and conditioning of the feet changes the requirements (65). However when it comes to the selection of footbeds various factors are paramount when considering soldiers or police personnel.Footbeds •

need to: Help protect feet and reduce /prevent MSD even when carrying heavy loads Delay fatigue Be durable and tough Provide adequate sensory stimulation to maintain foot health and fine motor control (dexterity) Protect against temperature extremes Have anti-bacterial & anti-fungal properties Be water resistant Be comfortable to wear Be cost-effective At this point we need to stress that it is important for a footbed to be providing support for the arches via appropriate stimulation without excessive rigidity. rigidity. This will prevent long-term problems such as support tissue atrophy and arch deterioration. In other words the footbed should not counteract the natural adaptive conditioning process, which people experience from prolonged physical stress. •

• • •

• •

• • •

Bearing this in mind, the e-bed™ again is ticking all the boxes. •

•

The specific invisible inbuilt contour creates all the support, stimulation and foot locking needed for safety and high performance (by stimulating arches, supporting excessive pronation/supination distortions and providing stability through engaging mid-foot locking and windlass locking, reverse windlass locking respectively) (15,16,32-49,54-63,90-108). Through its bilaminated polyurethane construction it delivers a dualaction shock absorption, providing protection from the damaging impact of weight bearing under heavy loads as well as significantly delaying fatigue (42-50).

 

•

• •

This dual-action shock absorption paired with the flat sole design provides great and immediate comfort without the need to wear them in. The polyurethane is a high quality insulator It also is very durable and robust, with an excellent memory lifespan (4-10 times longer then normal rubber or EVA compounds)

•

It is water resistant, anti-bacterial and fungicidal Importantly e-beds™ also are generic, meaning that one footbed fits all different foot types and can thus be worn by different people. Provided the shoe is right, fitting is no issue. And finally e-beds™ are very cost-effective (see INCREASED PRODUCTIVITY IN INDUSTRY / 42-45) On a side note: As many Navies require their personnel to wear flip-flops on board the e-flip™ would be the perfect solution as it is based on the ebed™ but comes in a flip-flop format format.. •

•

When considering all these factors it becomes obvious that e-beds™ (eflips™) should be the footbed of choice for Armed Forces and Law Enforcement Agencies around the world.

Diabetes /health Diabetes is a common condition that can contribute to illness, disability and early death. Diabetes is on the rise worldwide and in many countries it is the fastest growing chronic disease. The Australian Government for instance estimates that over 20% of its population is suffering from the disease and many are not even aware of it. Wor Worldwide ldwide it is estimated that 246 million people have the disease. Diabetes and its associated complications, which include heart, kidney and eyes diseases, affect the quality of life of a large number of people (74, 83-89). When looking at footwear for a person sufferi suffering ng from diabetes there are several factors to be considered: •

The shoe must minimise the risk of ulceration, which due to poor circulation and innervation is very common. Small blisters can develop into ulcerations, (75, 76, 79-83, 87, 89). which often lead to lower limb amputation

 

•

The shoe must be comfortable and have adequate shock absorption to minimise fatigue as seen in anti-fatigue matting (see INCREASED PRODUCTIVITY IN INDUSTRY). It must also provide micromovement in order to prevent blood pooling in the lower limbs, which will lead to an increased load on the cardiovascular system in particular the heart. Since heart issues are already a feature of

diabetes this needs be seriously (42-47,49,50,78,83,84 (42-47,49,50,78,83,84). Cardiovascular straintoshould further avoided be alleviated by an appropriate). soft orthotic contour in order to diminish ineffective biomechanics and MSD. The tricky part here is to use an effective orthotic contour that does not cause tissue irritation or scarfing (53, 61,75-78, 82). An effective generic orthotic contour not only diminishes stress on the wearer but also tends to be more cost effective than a custom made device. The innovative flat-sole design of the e-bed™ provides some unique and effective qualities well suited for people with sensitive feet, poor circulation and a need of proper support (as with diabetes). •

•

The flat-sole design prevents irritation and the formation of blisters from the footbed as the foot strikes a flat surface. As this surface is softish it feels comfortable yet still supportive. The latter comes from the gentile but definite stimulation of the invisibly inbuilt orthotic contour. The dual-action shock absorption allows for dispersive force dissipation through the upper layer in line with natural arch shock absorption. A further vertical absorption through the firmer bottom layer still allows for good control. The facilitation of the windlass and reverse windlass locking mechanisms (90-108) as well as the engagement of the natural mid foot locking mechanism (15,16) add further stability to the foot even in an open shoe (e.g. e-flip™). A complete complete orthotic contour also encourages a high quality sensory afferentiation afferenti ation leading to high-resolution brain mapping. This allows for good fine-motor control and maintenance of natural foot structure (arches etc) (4-12). Being a generic device it is very cost-effectiv cost-effectivee and versatile plus easy to fit. Likewise these qualities have also been shown to be useful in diminishing the incidence of spontaneous ankle bleeds in Haemophilia sufferer suffererss (110). •

Of course improving alignment, control and proper shock absorption with a smooth non irritating contact to the sole of the foot is a package that can assist in many health related disorders such as many types of arthridities (Osteo, Rheumatoid, Stills etc), MSDs (musculo skeletal disorders) such as overuse injuries, as well as NFP (neuro (neurophysiological physiological fatigue problems) (2,13,14,17-23, 28-37, 40, 41,109). As equilibras™ provide a foot bed (e-bed™) as well as an open shoe (eflip™) sufferers sufferers can now enjoy all those advantages anywhere, anytime.

Children The 26 bones and 35 joints of the human foot go through a major transformation in early childhood. It takes from 5 to 6 years until the triple arch configuration resembling that of an adult foot is achieved. Generally babies start off with flat feet. From the time they start to walk (8-18 months) the calcaneal (heel) inclination angle starts to increase, eventually tensing the plantar aponeurosis, giving rise to the foot arches (3, 26). This process is important to establish a proper windlass mechanism and thus stability through the various phasesstability of gait or tripleasarch structure can act as a tri-pod providing on stance. unevenThe ground, well

 

as a spring like shock absorber protecting the foot against the 3-5 g-forces produced during normal locomotion (1) As we have mentioned under STATUS QUO, it has not been that long since humans started living mostly in shoes and predominantly on flat, hard surfaces. This will understimulate the receptors of the foot preventing more and more often the child's foot from developing properly. In these cases early intervention is vital, for if a child continues to walk on this foot type, the condition rapidly becomes irretrievable. Due to these circumstances it makes sense to allow kids to walk as often as possible on soft natural (and safe) surfaces, which will also condition their feet properly. properly. Since that is often not possible in our modern urban societies, it is paramount to choose footwear wisely. The following are some of the important qualities to consider: •

The shoe should be wide and spacious as not to restrict foot growth. The sole must be soft and flexible as to allow for proper development of the foot architecture (90-108). A low, soft contoured foot bed is advisable to provide appropriate sensory stimulation, aiding in the correct natural foot development (4-12) Obviously external materials should be child friendly and non-toxic as well as comfortable. Let's now look at the performance of the e-bed™/e-flip™ in regards to these requirements: •

•

The e-flip™ in particular offers plenty of freedom for the foot, so it can develop without compromising the required qualities of the footbed. Both the e-bed™ as well as the e-flip™ are soft and flexible allowing for proper foot development. The invisible inbuilt contour is perfect for the development of the child's foot, as it is gentle yet highly stimulating and stabilising at the same time. It mimics walking on natural flat surfaces with various densities thus giving ample sensory stimulation for a proper foot development as well maintenance thereofand (4-12). The polyurethane has aaslong-lasting memory is completely nontoxic.

 

Let's not forget that proper foot development does not just affect the health of the feet but has an impact on the entire musculo skeletal system, the cardiovascular system and the nervous system (34-51,56-65). It is therefore very important and pertinent that parents and guardians carefully choose the footwear for children from the beginning as soon as they start to walk. A proper footbed (e-bed™ / e-flip™) is NOT A LUXURY but should be A UNIVERSAL REQUIREMENT REQUIREMENT if we are to seriously combat the ever worsening foot crisis we find ourselves in.

necessary market The common attitude to date by the general public as well as MANY health professionals seems to be that footbeds/orthot footbeds/orthotics ics are simply used to alleviate and help control existing problems. As we have seen this approach has some serious shortcomings and considering our current scientific knowledge (4 -12, 17,18, 29-40, 46-51, 61) this is not only inadequate but also illogical. Let us explain: Firstly we have to realise that potentially the vast majority of people are walking around unaware of their existing foot malfunctions. Unless they experience discomfort or symptoms that are linked to the feet how can they know?! Of course as any health care practitioner will tell you, problems frequently exist long before symptoms s ymptoms develop. Secondly it has been a longstanding debate within professional circles as to when and indeed whether kids should start to wear orthotics/specific footbeds as they are still in the developing phase. In light of the extensive research available regarding brain mapping and brain plasticity (4 -12) and the information presented in 'CHILDREN', the answer seems a "nobrainer". If we accept the premises that our lifestyle on predominantly flat surfaces with simple, flat footbeds understimulate our brain (poor sensory afferentiation afferenti ation leading to poor brain mapping creating inadequate foot control through our nervous system) leading eventually to a compromise of the foot structure, then logic dictates that kids as soon as they start weight natural bearing surfaces.(26) should be exposed extensively barefoot to uneven,

 

However since much of their lives tend to take place on flat, hard surfaces they SHOULD ALL ALL use footbeds, which offer the right stimulation for a healthy sensory afferent afferentiation. iation. This habit should then be maintained  throughout ones life, as the brain brain mapping is a continuous, continuous, dynamic  process allowing us constantly constantly to adapt to our environment. environment. Let's not

forget the other three core qualities we have discussed, as right from a young age their nervousofsystem will be reacting with NSR to any unfavourable exposure the feet. Due to the incredible results we are getting with e-flips™ and e-beds™ we have positioned our products in medical as well as more specialised fields. However as we now know everyone should wear equilibras™ - everyone should wear footwear with the properties included in equilibras™ especially the 4 core qualities: This footbed therefore addresses the following 4 core qualities: 1.Alignment (by preventing excessive pronation/supination causing negative kinetic chain reactions) 2.Stability (by engaging natural foot lock mechanisms thus also reducing stress on support tissues) 3. Shock Shock Absorpti Absorption on (dual-action for protection against MSD, NFP and Fatigue) 4. Adequate Sensory Afferent Afferentiation iation (for Brain Mapping, allowing for good quality fine motor control and maintenance of normal foot structure) FURTHER QUALITIES of PU are: 4 to 10 times more durable then rubber or EVA compounds (=much longer memory). It has anti-fungal and bactericidal properties. It is also water resistant. Insulating against temperature extremes. As one can see this simple looking flat-sole footbed (equilibras™ ebed™/e-flip™) is innovative and deceivingly complex. It packs a serious •

CHRONIC PAIN DOCUMENT

Introduction Initially our product (eflip™ by equilibras™) was invented out of frustration of seeing patients against better advice continuously wear unsupportive footwear such as flat•sole flip•flops. Market research of current footwear showed some serious shortcomings in the majority of footwear. footwear. This has most likely arisen from a lack of appreciation of this issue's complexity and multifactorial nature (130). Let me explain: Most footbeds these days have a very simplistic contour contour.. They usually have a medial arch contour with some material softness for simple shock absorption. Whilst custom•made orthotic footbeds are more sophisticated in their support they too appear to often lack the full spectrum of vital features, especially adequate shock absorption.

 

Mostly this appears to be due to a lack of proper appreciation of the body's neurophysiological feedback feedback system. If we mostly emphasis alignment we will always struggle to deal with the current foot crisis. Foot problems and their far•reaching effects on the body (kinetic chains, neurophysiological stress, psychosocial wellbeing) are happening in pandemic proportions Why? – It has not that long inon human history since we started(31). living our (urban) livesbeen predominantly flat, hard surfaces and mostly in shoes. This has resulted in severe understimulation of our foot soles and in fact feet as a whole. The consequence of this lack of sensory afferentiation has been poor brain mapping, which has led to poor fine motor control of the foot, followed by deterioration of the foot structure as can be seen today (19).  

Chronic Pain As we have come to understand chronic pain is not necessarily due to noxious stimuli from injured or diseased tissues. Rather it is a complex picture being influenced by a multitude of factors including psychosocial influences and early intervention after acute pain. For instance poorly managed acute pain paired with psychosocial influences can lead to central sensitization of the nervous system. These neuroplastic changes (brain mapping) can then evoke discomfort from relatively innocuous stimuli leading to chronic pain hyperalgesia)(3253). It has been demonstrated that interdisciplinary management, which emphasizes functional restoration produces the best outcomes in the management of chronic pain patients (32).

equilibras™ Let us therefore look at the various qualities and benefits that equilibras™ offer in order to support chronic pain sufferers:

 

This simple looking flat•sole footbed (ebed ™) or flip•flop (eflip ™) is packed with features never seen before in a flat sole and rarely found in its entirety even in custom made orthotic foot beds. MAKEUP. It is a bilaminated polyurethane construction with an invisible inbuilt orthotic contour. contour. The upper layer is relatively soft whereas the bottom, firmer. r. This makeup gives it some unique qualities.contoured layer is firme

Essentially the sole consists of: A triple arch support. A rearfoot control (heel inversion) A midfoot locking mechanism. Windlass Win dlass locking mechanism. A dual shock absorption system Antifatigue properties (!!) (Like the anti-fatigue matting, which is now used extensively at workplaces around the world High quality sensory afferenti afferentiation ation (brain mapping). BENEFITS 5 essential qualities need to be considered in shoes when dealing with chronic pain prevention and amelioration. • • • •

Good alignment via triple arch support (76) and rearfoot control (75) preventing excess ronation/supinat ronation/supination ion Great control by inducing the foot's natural mid•foot locking mechanism well asstability facilitating locking mechanism (57,62) (5474), as creating withthe lowwindlass tissue stress. High quality sensory afferentiation leading to detailed brain mapping is crucial in the maintenance of the foot structure and in finemotor control (19). A dual shock absorption (dispersive/vertical) (dispersive/vertical) effect in line with the natural architecture of the foot (10,1 (10,11). 1). An antifatigue effect lowering cardiovascular strain and general stress (as shown in extensive research in the anti-fatigue matting used now around the world) (2428).

 All these qualities are essential are the thus prevention prevention of foot p problems roblems as well as problems throughout throughout the bodyinand minimize the risk of developing chronicc pain conditions. chroni

 

The very same qualities are also important in assisting existing chronic pain conditions by minimising a neurophysiological stress reaction of the body and leading to a feeling of well being and more energy. Furthermore the flat esole does not have to be fitted nor worn in. It is very comfortable and 4 to 10 times more durable then standard rubber or EVA products. Since polyurethane has antibacterial and antifungal properties it is also useful in minimizing foot infections especially important in chronic pain sufferers with immune depression or predisposition predisposition to sores, such as in Diabetes. No wonder when testing equilibras™ in a double blind clinical trial for neurophysiological stress reactions, subjects wearing eflips ™ performed better then the control group tested at rest and showed no neurophysiological stress reactions whatsoever (10,11). A preliminary preliminary study performed at a medical school involving trigger•points as measured by a pressure gauze algometer has also yielded very encouraging results when wearing eflip ™. The feedback from current customers has been amazing and often disbelieve at the improvements of pain just from wearing a simple flip•flop even for relative short periods of time. equilibras™  orthotic neurophysiological neurophy siological device , a footbed combining forare thean first time essential orthotic qualities with comprehensive

neurophysiological properties properties in a fashionable flatsole shoe. It is the full package and we believe the best choice to date in medical footwear designed to support health and prevent or alleviate chronic pain conditions.
