Reversible insole

Abstract

A reversible insole for use inside a supportive boot, such as used for protection and support of the lower leg or foot after injury, is disclosed. The insole provides contouring on the opposite surfaces thereof which accommodates similar contours of the human foot. By alternately positioning the insole with the one surface or the other surface upward, a single insole can provide appropriate support for either the left of right foot inside an outer boot, such as a walker boot, that may be symmetrical from medial to lateral side. Such an outerboot may thus accommodate a left or right foot in a single product.

1 . A reversible insole, comprising: a body having a first surface and a second surface, the first surface having a non-linear, asymmetrical contour configured to accommodate a plantar surface contour of a left human foot, the second surface having a plantar surface contour of a right human foot, wherein the insole is reversibly positionable to orient the first surface or the second surface for contact with the human foot for supporting either the left human foot or the right human foot. 
     
     
         2 . The reversible insole of  claim 1 , wherein the insole is removably attachable to an adjacent lower surface of a walker boot. 
     
     
         3 . The reversible insole of  claim 1 , wherein the insole extends forward of distal ends of phalanges of a human foot and is foldable upwardly so as to be affixable within, or onto, a walker boot to protect and insulate a toe area of the foot. 
     
     
         4 . The reversible insole of  claim 1 , further including a horizontal oriented slot defined in a forward toe-side edge of the insole. 
     
     
         5 . The reversible insole of  claim 1 , further including a horizontal oriented slot defined in a rearward heel-side edge of the insole. 
     
     
         6 . A walker boot system, comprising:
 a walker boot configured to receive both the right foot or the left foot of a user; and   a reversible insole removably and reversibly positionable within the walker boot to receive the left foot or the right foot of the user, the reversible insole including a body having a first surface and a second surface, the first surface having a non-linear, asymmetrical contour configured to accommodate a plantar surface contour of a left human foot, the second surface having a plantar surface contour of a right human foot, wherein the insole is reversibly positionable within the boot to orient the first surface or the second surface for contact with the human foot for supporting either the left human foot or the right human foot.   
     
     
         7 . The walker boot system of  claim 6 , wherein the insole extends forward of distal ends of phalanges of a human foot and is foldable upwardly within the walker boot so as to be affixable within, or onto, the walker boot to protect and insulate a toe area of the foot. 
     
     
         8 . The walker boot system of  claim 6 , further including a horizontal oriented slot defined in a forward toe-side edge of the insole. 
     
     
         9 . The walker boot system of  claim 6 , further including a horizontal oriented slot defined in a rearward heel-side edge of the insole.
