Method for interchangeable shoe sole

Abstract

A method for interlocking a shoe sole can provide the ability for the shoe sole to be attached or removed. For example, a shoe wearer may want the ability to change his or her shoe soles for aesthetic purposes. The shoe sole can also comprise additional functionality for the shoe wearer. For example, a method of also using the shoe sole as storage is discussed herein.

What is claimed is: 
     
         1 . A method, comprising:
 stretching an elastic member of an upper sole of a shoe from a first position to a second position, wherein the upper sole of the shoe comprises a first lip;   attaching a lower sole of the shoe to the upper sole of the shoe by inserting a second lip of the lower sole into a recess formed by the first lip of the upper sole; and   releasing the upper sole of the shoe to facilitate an interlocking of the upper sole to the lower sole as a result of the elastic member returning to the first position.   
     
     
         2 . The method of  claim 1 , wherein the first lip comprises a sealing material to prevent moisture from entering between the upper sole and the lower sole. 
     
     
         3 . The method of  claim 3 , the second lip comprises a sealing material to prevent moisture from entering between the upper sole and the lower sole. 
     
     
         4 . The method of  claim 3 , wherein the stretching comprises stretching the elastic member to facilitate the attaching of the lower sole to the upper sole. 
     
     
         5 . The method of  claim 4 , further comprising:
 stretching the elastic member to facilitate removing the lower sole of the shoe.   
     
     
         6 . The method of  claim 5 , further comprising:
 inserting a cushion into a compartment of the lower sole of the shoe to provide support for a user of the shoe prior to attaching the lower sole of the shoe to the upper sole of the shoe.   
     
     
         7 . The method of  claim 6 , further comprising:
 storing an object in the lower sole of the shoe prior to attaching the lower sole of the shoe to the upper sole of the shoe.   
     
     
         8 . The method of  claim 5 , further comprising:
 inserting a hot pack into a compartment of the lower sole of the shoe to generate heat for a user of the shoe.   
     
     
         9 . The method of  claim 5 , further comprising:
 inserting a cold pack into a compartment of the lower sole of the shoe to generate cold for a user of the shoe.   
     
     
         10 . The method of  claim 8 , further comprising:
 inserting an odor eater into a compartment of the lower sole to reduce a shoe odor.   
     
     
         11 . A method, comprising:
 stretching an elastic member of an upper sole of a shoe from a first position to a second position, wherein the upper sole of the shoe comprises a retractable locking mechanism;   attaching a lower sole of the shoe to the upper sole of the shoe by retracting the retractable locking mechanism allowing the lower sole to be inserted into a recess of the upper sole; and   releasing the retractable locking mechanism to facilitate an interlocking of the upper sole to the lower sole as a result of the elastic member returning to the first position.   
     
     
         12 . The method of  claim 11 , wherein the retractable locking mechanism comprises a sealing material to prevent moisture from entering between the upper sole and the lower sole. 
     
     
         13 . The method of  claim 13 , the upper sole comprises a sealing material to prevent moisture from entering between the upper sole and the lower sole. 
     
     
         14 . The method of  claim 13 , wherein the stretching comprises stretching the elastic member to facilitate the attaching of the lower sole to the upper sole. 
     
     
         15 . The method of  claim 14 , further comprising:
 stretching the elastic member to facilitate removing the lower sole of the shoe.   
     
     
         16 . The method of  claim 14 , further comprising:
 inserting a cushion into a compartment of the lower sole of the shoe to provide support for a user of the shoe prior to attaching the lower sole of the shoe to the upper sole of the shoe.   
     
     
         17 . The method of  claim 16 , further comprising:
 storing a key in the lower sole of the shoe prior to attaching the lower sole of the shoe to the upper sole of the shoe.   
     
     
         18 . The method of  claim 17 , further comprising:
 inserting a hot pack into a compartment of the lower sole of the shoe to generate heat for a user of the shoe prior to attaching the lower sole of the shoe to the upper sole of the shoe.   
     
     
         19 . The method of  claim 18 , further comprising:
 inserting a cold pack into a compartment of the lower sole of the shoe to generate cold for a user of the shoe prior to attaching the lower sole of the shoe to the upper sole of the shoe.   
     
     
         20 . The method of  claim 19 , further comprising:
 inserting an odor eater into a compartment of the lower sole to reduce a shoe odor prior to attaching the lower sole of the shoe to the upper sole of the shoe.
