Abstract

A footwear system comprising an external chassis comprising a flexible upper attached to a molded cushion and grip component further comprising a molded midsole, a plurality of interchangeable internal cushion and fit components that fit inside the external chassis and are held in place by an interference fit, wherein the internal cushion and fit components comprise different morphologies and can be replaced by the user without the use of any tools.

What is claimed is: 
     
         1 . A footwear system comprising:
 an external chassis comprising a flexible upper attached to a molded cushion and grip component further comprising a molded midsole,   a plurality of interchangeable internal cushion and fit components that fit inside the external chassis and are held in place by an interference fit,   wherein the internal cushion and fit components comprise different morphologies and can be replaced by the user without the use of any tools.   
     
     
         2 . The footwear system of  claim 1 , wherein the user is provided with three different internal cushion and lit components.
