Shoe system with a resilient shoe insert

Abstract

The shoe system comprises a shoe that has an upper rim section. A shoe sole is disposed inside the shoe and has a top layer. A shoe insert has a stiff first member and a resilient second member attached to the first member so that the first member is attached to the top layer of the shoe sole. The second member is movable between a compressed position immediately adjacent to the first member and an expanded position remote from the first member. The first member is disposed a first distance from the upper rim section when the second member is in the compressed position and the first member being disposed the same first distance from the upper rim section when the second member is in the expanded position.

We claim:  
     
         1 . A method of making a shoe system having a resilient shoe insert, comprising: 
 providing a shoe having an upper rim section and a shoe sole disposed inside the shoe, a shoe insert having a stiff first member and a resilient second member attached to the first member, a first compressible material being disposed between the first and second members, the compressible material having a first hardness, the first member being disposed a distance (X) from the upper rim and a distance (A) from a bottom side of the shoe sole;    putting a load (L) on the shoe;    compressing the second member towards the first member while maintaining the first member at the distance (X) from the upper rim and reducing the distance (A) to a distance (B), the distance (A) being greater than the distance (B),    removing the first compressible material; and    inserting a second compressible material having a second hardness, the second material being harder and stiffer than the first material.    
     
     
         2 . The method according to  claim 1  wherein the method further comprises removing the load (L) and expanding the shoe sole so that the second member is moved relative to the first member from the distance (B) back to the distance (A).  
     
     
         3 . The method according to  claim 1  wherein the method comprises raising a heel portion of the shoe when the load (L) is removed from the shoe.  
     
     
         4 . The method according to  claim 1  wherein the method comprises lowering a heel portion of the shoe to a height that is the same as a height of a toe portion of the shoe.
