Size adjustable shoe

Abstract

A size adjustable shoe having a heel curtain that is transformable, for example by folding, between a first position and a second position such that the size of the shoe is smaller when the heel curtain is in the first position than when it is in the second position.

I claim: 
     
         1 . A size adjustable shoe comprising:
 a sole portion and an upper portion coupled to the sole portion, the upper portion comprising a heel portion,   wherein a heel curtain is coupled adjacent a topline of the heel portion, and the heel curtain is transformable between a first position adjacent to a first surface of the heel portion and a second position adjacent to a second surface of the heel portion,   wherein an inner dimension of the shoe has a first measurement when the heel curtain is in the first position,   wherein the inner dimension of the shoe has a second measurement when the heel curtain is in the second position, and   wherein the first measurement is not equal to the second measurement.   
     
     
         2 . The shoe of  claim 1 , wherein the first surface is an inner surface of the heel portion and the second surface is an outer surface of the heel portion. 
     
     
         3 . The shoe of  claim 2 , wherein the inner dimension is length and the first measurement is less than the second measurement. 
     
     
         4 . The shoe of  claim 1 , wherein the heel curtain comprises a curtain tab and wherein the heel portion comprises a tab aperture. 
     
     
         5 . The shoe of  claim 4 , wherein, when the heel curtain is in the first position, the curtain tab extends through the tab aperture. 
     
     
         6 . The shoe of  claim 5 , wherein, when the heel curtain is in the first position, the curtain tab is coupled to a tab lock on the heel portion. 
     
     
         7 . The shoe of  claim 6 , wherein the tab lock comprises one of a button, a hook and loop fastener and a clip. 
     
     
         8 . The shoe of  claim 1 , wherein the heel curtain comprises a curtain plug and wherein the heel portion comprises a plug receptacle. 
     
     
         9 . The shoe of  claim 8 , wherein, when the heel curtain is in the first position, the curtain plug extends into a side of the plug receptacle. 
     
     
         10 . The shoe of  claim 9 , wherein, when the heel curtain is in the second position, the curtain plug extends into an opposite side of the plug receptacle. 
     
     
         11 . A size adjustable shoe comprising:
 a sole portion and an upper portion coupled to the sole portion, the upper portion comprising a heel portion,   wherein a heel curtain is coupled adjacent a topline of the heel portion, the heel curtain transformable between a first position adjacent to an inner surface of the heel portion and a second position adjacent to an outer surface of the heel portion,   wherein the heel curtain comprises a curtain plug and wherein the heel portion comprises a plug receptacle,   wherein an inner dimension of the shoe has a first measurement when the heel curtain is in the first position,   wherein the inner dimension of the shoe has a second measurement when the heel curtain is in the second position, and   wherein the first measurement is less than the second measurement.   
     
     
         12 . The shoe of  claim 11 , wherein, when the heel curtain is in the first position, the curtain plug extends into a side of the plug receptacle. 
     
     
         13 . The shoe of  claim 12 , wherein, when the heel curtain is in the second position, the curtain plug extends into an opposite side of the plug receptacle. 
     
     
         14 . A size adjustable shoe comprising:
 a sole portion and an upper portion coupled to the sole portion, the upper portion comprising a heel portion,   wherein a heel curtain is coupled adjacent a topline of the heel portion, the heel curtain transformable between a first position adjacent to an inner surface of the heel portion and a second position adjacent to an outer surface of the heel portion,   wherein the heel curtain comprises a curtain tab and wherein the heel portion comprises a tab aperture,   wherein an inner dimension of the shoe has a first measurement when the heel curtain is in the first position,   wherein the inner dimension of the shoe has a second measurement when the heel curtain is in the second position, and   wherein the first measurement is less than the second measurement.   
     
     
         15 . The shoe of  claim 14 , wherein, when the heel curtain is in the first position, the curtain tab extends through the tab aperture. 
     
     
         16 . The shoe of  claim 15 , wherein, when the heel curtain is in the first position, the curtain tab is coupled to a tab lock on the heel portion. 
     
     
         17 . The shoe of  claim 16 , wherein the tab lock comprises one of a button, a hook and loop fastener and a clip.
