The unique and patented* shape of Footbionics is somewhat radical by orthotic standards. In fact it goes completely against the current grain of using a flat based orthotic like nearly every other device on the market. It was no surprise in perfecting our design, that the curved underside is similar in shape to the human foot, and also the "prescription orthotic" shell commonly used by podiatrists. This shape is the critical element in the success of our product.
Hemispherical Heel Cup
This is one our trademark features. The heel cup is almost hemispherical providing exceptional cushioning and customisation options for the practitioner. Upon loading the heel cup will compress downward and flatten slightly providing a cushioning effect.. This unique design is extremely comfortable as it will accommodate varying heel shapes with ease. Being rounded allows the concave shape to cup the heel literally. Despite being rounded the orthotic is supported by the shoe itself to maintain exceptional stability. Modifications to the heel region are limitless. This is just like working with a prescription orthotic shell. Foam can be added to the heel region to provide more subtle support, or more aggressively to improve foot alignment.
Footbionics arch profiles are supportive yet not aggressive. Our models therefore are tolerated exceptionally well. The importance of the windlass mechanism in foot function has ensured that our design avoided excessive medial blocking in the arch region. The underside of the arch region is upwardly contoured in both the transverse and sagittal planes. This allows the orthotic to flex downward slightly under load for the perfect fit and feel. This also helps to reduce plantar fascial stress from the medial arch. This rounded shape allows for accommodation of the midfoot by cupping this area nicely. On weightbearing there is slight deformation however the orthotic is supported by the shoe itself therefore maintaining orthotic stability.
Arch Declination Angle
One of the issues with many orthotic devices is the irritability caused from the distal arch. In addition to this blocking the medial column of the foot is theorised to have negative functional consequences. Our declination angle is high to avoid arch pressure and allow for the 1st metatarsal to plantarflex. Despite the relatively high arch appearance the wearer will often feel little pressure in this area.
The rounded arch contours allows the practitioner to subtly add posting or fills to a curved device without effecting the orthotic as a whole. Filling in the gaps certainly provides the practitioner with much more versatility in device customisation. The concave underside of the orthotic ensures however that the practitioner can easily modify the product with the use of the footbionics Quick Kit pre-moulded additions. Nothing could be simpler in using these Footbionics rearfoot, arch and forefoot additions that are seamless and offer instant motion control.
We have really pushed the boundaries in our Footbionics design and look forward to continue our lead in taking orthoses to another level.
