Toe-fortifiable footwear and toe-fortifiable insole member of footwear

Abstract

Toe-fortifiable footwear includes a sole portion and a step formation member of a constant thickness attached to an inside of the footwear. The step formation member has a forward end part that forms a step part for having an insole surface of the footwear divided into a first insole surface part for toes and a second insole surface part constituting a top surface of the step formation member for a plantar surface exclusive of the first insole surface. The first and second insole surface parts differ in height by the constant thickness. The step formation member may be used as a separate toe-forcible insole member.

1 . Toe-fortifiable footwear having an insole surface that has a step part for dividing the insole surface into a first insole surface part for toes and a second insole surface part for a plantar surface having a height larger than the first insole surface part. 
     
     
         2 . Toe-fortifiable footwear comprising a sole portion and a step formation member of a constant thickness attached to an inside of the footwear, the step formation member having a forward end part that forms a step part for having an insole surface of the footwear divided into a first insole surface part for toes and a second insole surface part constituting a top surface of the step formation member for a plantar surface exclusive of the first insole surface, which insole surface parts differ in height by the constant thickness. 
     
     
         3 . Toe-fortifiable footwear according to  claim 2 , wherein the forward end part of the step formation member is tapered to make the step part tapered. 
     
     
         4 . Toe-fortifiable footwear according to  claim 2 , wherein the forward end part of the step formation member is formed into a shape in conformity with a contour of toe root joints. 
     
     
         5 . Toe-fortifiable footwear according to  claim 2 , wherein the step formation member is formed of an elastic material having a cushioning property including rubber and plastic. 
     
     
         6 . A toe-fortifiable insole member having a constant thickness, detachably attached to an inside of footwear and having a forward end part that forms a step part for having an insole surface of the footwear divided into a first insole surface part for toes and a second insole surface part constituting a top surface of the insole member for a plantar surface exclusive of the first insole surface, which insole surface parts differ in height by the constant thickness of the insole member. 
     
     
         7 . A toe-fortifiable insole member according to  claim 6 , wherein the forward end part is tapered to make the step part tapered. 
     
     
         8 . A toe-fortifiable insole member according to  claim 6 , wherein the forward end part is formed into a shape in conformity with a contour of toe root joints. 
     
     
         9 . A toe-fortifiable insole member according to  claim 6 , wherein it is formed of an elastic material having a cushioning property including rubber and plastic.
