Functional foot cover

Abstract

A cover for a foot prosthesis comprises an opening at a top end of the cover, which extends into a cavity formed within the cover, wherein the cavity is configured to receive a prosthesis therein. A wall surrounds the cavity and has the shape of a natural human foot. The wall has an inner surface and an outer surface. The wall also has a top section, a bottom section and a rear section. The bottom section defines a sole area having a toe section, a heel section, and a metatarsal region, wherein the sole area is provided with varying levels of stiffness configured to induce a desired rollover from heel-to-toe in a lateral-to-medial direction.

1 . A prosthetic foot, comprising:
 a body having an outer surface that defines an upper portion and a sole of the prosthetic foot, the outer surface having the shape and contours of a natural human foot;   the sole having a traction surface thereon configured to increase traction of the prosthetic foot on wet or slippery surfaces.   
     
     
         2 . The prosthetic foot of  claim 1 , wherein the traction surface is formed in a pattern configured to increase traction of the foot during use. 
     
     
         3 . The prosthetic foot of  claim 1 , wherein the traction surface is molded to the sole during manufacture. 
     
     
         4 . The prosthetic foot of  claim 1 , wherein the sole comprises a toe section, a heel section, and a metatarsal region. 
     
     
         5 . The prosthetic foot of  claim 4 , wherein the traction surface covers one or more of the toe section, heel section, and metatarsal region of the sole. 
     
     
         6 . The prosthetic foot of  claim 1 , wherein the body surrounds a cavity configured to receive a prosthetic foot insert therein. 
     
     
         7 . The prosthetic foot of  claim 4 , wherein the toe section comprises five toes so that the toe section has the appearance of natural human toes. 
     
     
         8 . The prosthetic foot of  claim 7 , wherein the toe section comprises a slot between at least two of the toes, the slot configured to receive a strap of a sandal. 
     
     
         9 . A prosthetic foot, comprising:
 a body having an upper portion and a sole portion, an outer surface of the body on the upper and sole portions and extending between a rear end and a front end of the body having the shape and contours of a natural human foot such that the body has the appearance of a natural human foot;   wherein the outer surface on the sole portion has at least one area of non-slip material, said non-slip material configured to increase traction of the prosthetic foot on wet or slippery surfaces.   
     
     
         10 . The prosthetic foot of  claim 9 , wherein the area of non-slip material is located on one or more of a toe section, a heel section, and a metatarsal region of the sole portion. 
     
     
         11 . The prosthetic foot of  claim 9 , wherein the body comprises a cavity configured to receive a prosthetic foot insert therein. 
     
     
         12 . The prosthetic foot of  claim 9 , wherein a toe region of the body comprises five toes so that the toe region has the appearance of natural human toes. 
     
     
         13 . The prosthetic foot of  claim 12 , further comprising a slot between at least two of the toes. 
     
     
         14 . The prosthetic foot of  claim 13 , wherein the slot is configured to receive a strap of a sandal. 
     
     
         15 . A prosthetic foot, comprising:
 a body comprising:
 an upper portion formed as a single piece body with a sole portion, the sole portion having a toe section, a heel section, and a metatarsal region; and 
 an outer surface having the shape and contours of a natural human foot such that the body has the appearance of a natural human foot; 
   wherein the sole portion is provided with at least one area of non-slip material, the non-slip material configured to increase traction of the prosthetic foot on wet or slippery surfaces.   
     
     
         16 . The prosthetic foot of  claim 15 , wherein the body comprises an opening at a top end of the body extending into a cavity formed within the body, the cavity configured to receive a prosthetic foot insert therein. 
     
     
         17 . The prosthetic foot of  claim 15 , wherein said at least one area of non-slip material is molded to the sole portion during manufacture. 
     
     
         18 . The prosthetic foot of  claim 15 , wherein said at least one area of non-slip material is applied to the outer surface of the sole portion. 
     
     
         19 . The prosthetic foot of  claim 15 , wherein said non-slip material comprises silicone. 
     
     
         20 . The prosthetic foot of  claim 15 , wherein said at least one area comprises three areas disposed on the outer surface of the toe section, heel section, and metatarsal region of the sole portion.
