Dynamic Insole

Abstract

A dynamic insole that flexes and returns as the plantar fascia flex and return, comprising a medial first windlass-shaped front cutout for great toe phalanges and a lateral second diagonal-shaped front cutout for fourth and fifth toe phalanges, further comprising medial and lateral upwardly-curved side walls wherein a medial side wall comprises a lobe, and made from a first material having a hardness value between 40 Shore A and 90 Shore A.

I claim: 
     
         1 . A dynamic insole comprising an insole proximal end to be worn adjacent a wearer's leg, an insole distal end, an insole upper surface, an insole lower surface and insole thicknesses, and insole edges where the form-fitted insole upper surface and the insole lower surface meet, wherein the insole further comprises:
 a form-fitted insole upper surface that is fitted to contours of a wearer's foot;   a first material having a hardness between 40 Shore A and 90 Shore A which enables the insole under a weight of a wearer's foot to deflect downwards from an original position and then return back to the original position;   insole thicknesses tapering down into the insole edges;   a medial arch support;   a deep heel cup;   a flat heel portion in the insole lower surface;   a medial upwardly-curved side wall and a lateral upwardly-curved side wall for cradling a foot;   a lobe for widening the insole, wherein the lobe extends from the medial upwardly-curved side wall;   a first windlass-shaped cutout at the insole distal end that reveals metatarsal heads I and II;   a second diagonal-shaped cutout for fourth and fifth toe phalanges that reveals metatarsal heads III, IV and V; and   an insole distal end tongue between and formed by the first and second cutouts, the insole distal end tongue comprising a flat lower surface.   
     
     
         2 . The insole of  claim 1 , wherein the first material is dual-density ethylene-vinyl acetate foam. 
     
     
         3 . The insole of  claim 1 , wherein the first material has a hardness value of 45 Shore A.
