Method and apparatus for interchangeable shoe sole

Abstract

An interlocking mechanism for a shoe 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, the shoe sole itself provide storage and/or lighting capabilities.

What is claimed is: 
     
         1 . A shoe, comprising:
 an upper sole, wherein the upper sole comprises:
 a lip for interlocking with a lower sole; and 
 an elastic member that spans a width of the upper sole for facilitating the interlocking with the lower sole. 
   
     
     
         2 . The shoe of  claim 1 , wherein the elastic member is a first elastic member, further comprising:
 a second elastic member on a medial of the upper sole.   
     
     
         3 . The shoe of  claim 1 , wherein the elastic member is a first elastic member, further comprising:
 a second elastic member on a lateral side of the upper sole.   
     
     
         4 . The shoe of  claim 1 , wherein the elastic member is in front of a mid-sole area of the shoe. 
     
     
         5 . The shoe of  claim 1 , wherein the elastic member is a retractable system that allows a front portion of the upper sole and a rear portion of the upper sole to expand or retract. 
     
     
         6 . The shoe of  claim 1 , wherein the elastic member comprises a rubber. 
     
     
         7 . The shoe of  claim 1 , wherein the lip comprises a rubber portion to seal the upper sole to the lower sole. 
     
     
         8 . A shoe, comprising:
 an upper sole, wherein the upper sole comprises an elastic member, and wherein the upper sole comprises a first lip; and   a lower sole, wherein the lower sole comprises a second lip for interlocking with the first lip of the upper sole.   
     
     
         9 . The shoe of  claim 8 , wherein the lower sole comprises a recessed compartment for storage. 
     
     
         10 . The shoe of  claim 8 , wherein the lower sole comprises a massaging component capable of massaging a user's foot. 
     
     
         11 . The shoe of  claim 8 , wherein the lower sole comprises a memory foam. 
     
     
         12 . The shoe of  claim 8 , wherein the lower sole comprises a lighting component. 
     
     
         13 . The shoe of  claim 8 , wherein the lower sole comprises a tracking component for tracking a location of the shoe. 
     
     
         14 . The shoe of  claim 8 , wherein the lower sole comprises a roller component. 
     
     
         15 . 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.   
     
     
         16 . The method of  claim 15 , wherein the first lip comprises a sealing material to prevent moisture from entering between the upper sole and the lower sole. 
     
     
         17 . The method of  claim 15 , the second lip comprises a sealing material to prevent moisture from entering between the upper sole and the lower sole. 
     
     
         18 . The method of  claim 15 , wherein the stretching comprises stretching the elastic member to facilitate the attaching of the lower sole to the upper sole. 
     
     
         19 . The method of  claim 15 , further comprising:
 stretching the elastic member to facilitate removing the lower sole of the shoe.   
     
     
         20 . The method of  claim 15 , further comprising:
 inserting a cushion into a compartment of the lower sole of the shoe to provide support for a user of the shoe.
