Definitions

  • the present invention relates to footwear having stabilising systems for fully supporting the wearer's feet.

  • the vertical energy transferred through the ankle joint at the 'heel strike' of the foot - can be many as much as 8 times greater than the body weight.
  • the resultant damage can be lower back pain, knee pain, hip displacement, overall muscle trauma and foot and ankle conditions such as; Plantar fasciitus, fallen arches, corns, callous pain and potential bunion problems.
  • a sole for an in-house shoe comprising a resiliently deformable heel pad which, in use, locates in a recess in a base of the shoe so as to be flush with the upper surface thereof, a support layer extends are least partially over the upper surface of the base so as to overlie the heel pad, and a removable insole which overlies the support layer and any exposed upper surface of the base.
  • a sole in accordance with the invention has the advantage that the control of the Arch contour of the 'insole' during the 3 phases of each step (ie Heel Strike, Mid Stance and Toe Off), combined with the support layer and the 'heel pad' to support and cushion the Plantar surface of the foot, within the guidelines of the outer shell - dramatically slows down the progression of the damaging transitional forces of 'shear' and 'load' - from 'Heel strike' to 'toe off .
  • This combination of the 3 or 4 sections is the 'key' USP - that no prior art system replicates.
  • the system further includes an outer shell forming the base of the sole and having a recess in its upper surface in the area of the heel in which the deformable heel pad locates.
  • the support layer is formed from PVC or a polyurethane or similar material and the insole is made out of polyurethane material and has a lower durometer than the support layer.
  • the support layer preferably extends only partially across the base, in particular 3 A of the way thereacross, supporting the heel and the Plantar surface of the foot, i.e. cradles the arch and maintains the Calcaneous (heel) in the correct position for healthy walking.
  • the heel pad is preferably made out of a gel material, in particular a bio-gel material.

  • the support layer is preferably profiled to support the instep of the foot and also curves upwards around the rear portion of the foot.
  • the back half of the support layer is pitched upwards at substantially 2 degrees in a low heel format for providing effective support for wears of low heel shoes.
  • the support layer is pitched upwards at a greater angle, in particular substantially 6 degrees, in order to provide effective support for persons having a shorter Achilles, such as wearers of high heels.

  • An absorbency Heel Pad 2 sits flush in a heel cup 3 formed in the outer shell 1 and acts as an additional fat Pad under the wearer's heel, dissipating the 'downward' force into a less damaging dispersed energy on impact at heel strike.
  • the exo-skeleton is not essential to the implementation of the invention. It acts as a complete support cradle for the FST support mechanism with a built in 'toe spring'.
  • the Heel Pad 2 may be made out of a Silicon or Bio-Gel type of material and is resiliently deformable, with a 100% memory status allowing the material to cushion, off load and return to its normal shape during the 3 phases of each step during walking.
  • a three quarter Comfort stabilizer 4 sits above the Heel Pad 2 and acts as the integral support to the Plantar surface of the foot i.e. cradles the arch and maintains the heel in the correct position for healthy walking around the house.

  • outer shell 1 is profiled to extend around the sides of the wearer's foot, enclosing the other layers and supporting the lowers part of the foot during movement.
  • outer shell 1 includes a profiled section 10 which engages and supports the instep of the foot as shown in Figure 5b.
  • the outer shell 1 furthermore has a recess formed on its inner flat surface Ib in the area of the heel forming a heel cup 3 in which is received the heel pad 2 as illustrated in Figure 4, which is formed preferably from a gel cushioning material, in particular it is a Bio Gel pad which offers complete comfort and a feeling of enhanced propulsion during every step taken.
  • the comfort stabiliser 4 is locates over the heel pad 2 and extends across the inner foot support surface Ib of the outer shell 1.
  • the foot bed 5 locates on top of the comfort stabiliser so as to form the insole on which the bottom of the wearer's foot engages.
  • the foot bed 5 is generally flat towards the front end which underlies the toes, but is contoured towards the rear to extend partially around the sides and also partially up the back of the heel of the foot and also support the instep of the foot.
  • the outer shell 1, heel pad 2 and comfort stabiliser 4 are all adhered together using an suitable means, whereas the foot bed 5 is removeable and in particular may be moulded in order to properly support the particular users foot.
  • FIG. 7 to 9 there is shown a second embodiment of the invention for feet have shortened Achilles, e.g. women who wear high heels.
  • the basis construction of the system is the same as for the first embodiment except that the comfort stabiliser 14 and foot bed 15 are raised at the heel as shown in Figures 7b and 8a so as to provide additional support to the wearer.
  • the 'F-S-T' system of the invention is a system of cushioning and support built into the inner and outer sole of the slipper - offering the transfer of Kinetic energy during the gait cycle - within a controlled and supportive environment.
  • F-S-T encompasses the latest material technology available - allowing the negative forces of 'shock' to be converted into to a positive propulsive kinetic energy.
  • the F-S-T is a combination of 4 parts:
  • the F-S-T slipper will come with it's own removable foot beds - that complements and work in tandem with the F-S-T system. Version are provided either for normal foot type (Figure 4b) or specific for high heel shoe wearers (Figure 4c)- visualised in this document as two parts - the actual final design is one unit as an integral design. This attribute will be a unique USP, allowing the wearer to always have the correct cushioning and support in the house, without aggravating the Achilles tendon.
  • the F-S-T slipper has an additional 'gel' cushioning mechanism that is placed under the innersole units and within the base of the outer heel as shown in Figure 4a.
  • This Bio Gel - pad offers complete comfort and a feeling of enhanced propulsion during every step taken.
  • a three quarter 'Stabilizer' sits beneath the 'Heel Pad' and acts as an integral support to the Plantar surface of the foot ie; cradles the arch and maintains the Calcaneous (heel) in the correct position for healthy walking around the house. See Figure 8c.
  • the stabilizer offers shock dissipation and absorption - while at the same time controlling the rotational forces during gait, stabilizing both the mid and hind foot during walking.
  • PART FOUR The F-S-T Slipper has the exterior shell design that works as an 'exoskeleton' support for the slipper - offering an outer shell to house the component elements and protect and support the foot in its entirety during wear (Figure 5b).
  • the foot bed has an anatomical design to ensure 100% pro-prioceptive contact at all times.
  • AU materials used are chosen for their absorption and shock attenuation qualities
  • Air holes in the forefoot - ensure improved airflow around the foot at all times, while additional cushioning underneath the lateral calcaneous (outside heel - heel strike), the l st /2 nd /3rd metatarsals (Balls of foot - toe-off), guarantees comfort at every phase of gait.
  • AU inner materials are chosen to prevent skin irritation and encourage circulation without slippage or friction
  • F.S.T - with the option of 3 or 4 parts - can be utilized in any style of inhouse footwear and outdoor footwear (in the future) a.
  • the VA stabilizer (PART 3), enables complete flexibility within style or usage of footwear and will be applicable with slippers, shoes, boots and also performance footwear - such as trainers b.
  • the full length Exo-skeleton addition (PART 4), is more specific to a certain style of footwear, be it in-house or outdoor. Described essentially as a rigid 'CLOG' effect on the footwear.
  • Heel absorber could be manufactured from special 'BIO-GEL' compounds for shock dissipation.
