Variable Length and Flexible Forefoot Shoe

Abstract

The invention is a shoe that has a variable length and flexible shape realized because of a flexible sectional sole and a flexible upper corresponding to the forefoot section of the user's foot. These flexible portions of the shoe permit bending of the forefoot relative to the rest of the shoe to change the length and shape of the forefoot and the length of the upper vamp of the shoe in order to allow a player to achieve maximum results in sports where feet and shoes are the player's tools, where the shoe aids in using the maximum number of sweet spots of the shoe for control, distance, and accuracy. The invention is an improvement over the prior art by allowing a user to better approximate the natural flexibility of bare feet as opposed to rigid shoes that limit a player's ability to use the natural flexibility of their feet.

1 . A shoe comprising:
 a variable total length of the shoe where changes in the total length correspond to a position of a user's forefoot;   a variable upper vamp length where changes in the upper vamp length correspond to the position of the user's forefoot;   an inelastic outsole distal forefoot;   an inelastic outsole inside proximal forefoot;   an inelastic outsole outside proximal forefoot;   a inelastic midfoot/hindfoot;   an elastic outsole interface between the inelastic outsole distal forefoot and the inelastic outsole inside and outside proximal forefoot;   an elastic outsole interface between the inelastic outsole inside and outside proximal forefoot and the inelastic midfoot/hindfoot;   an elastic upper distal forefoot;   an elastic upper proximal forefoot;   an upper midfoot/hindfoot.   
     
     
         2 . The shoe from  claim 1  with the total length at a maximum and the upper vamp length at a minimum when the user's forefoot is bent up. 
     
     
         3 . The shoe from  claim 1  with the total length at a minimum and the upper vamp length at a maximum when the user's forefoot is bent down. 
     
     
         4 . The shoe from  claim 1  wherein the upper distal forefoot is inelastic. 
     
     
         5 . A shoe comprising:
 a changing shape for ball grasping depending on a position of a user's forefoot;   an inelastic outsole distal forefoot;   an inelastic outsole inside proximal forefoot;   an inelastic outsole outside proximal forefoot;   a inelastic midfoot/hindfoot;   an elastic outsole interface between the inelastic outsole distal forefoot and the inelastic outsole inside and outside proximal forefoot;   an elastic outsole interface between the inelastic outsole inside and outside proximal forefoot and the inelastic midfoot/hindfoot;   an elastic upper distal forefoot;   an elastic upper proximal forefoot;   an upper midfoot/hindfoot.   
     
     
         6 . The shoe from  claim 5  with the changing shape for ball grasping shape upward when the forefoot is bent up. 
     
     
         7 . The shoe from  claim 5  with the changing shape for ball grasping shape downward when the forefoot is bent down. 
     
     
         8 . The shoe from  claim 5  with the changing shape for ball kicking shape downward and inward when the forefoot is bent down and the forefoot is twisted inward. 
     
     
         9 . An insole comprising:
 a compressing and stretching of an insole elastic region corresponding to a force from a user's foot;   a transmitting of the user's forefoot force and shape changes to the elastic region of the shoe;   an inelastic insole distal forefoot;   an inelastic insole proximal forefoot;   an inelastic insole midfoot/hindfoot;   an elastic distal forefoot to proximal forefoot interface;   an elastic proximal forefoot to midfoot/hindfoot interface.
