Abstract

A non-cupping heel cushion for a shoe with one or more upper terraces with internal cavities with following lower terraces having a larger area than the one above wherein the upper terraces are subsumed sequentially by the lower larger terraces.

I claim:

         4 . The non-cupping cushion of  claim 1  wherein the terraces are elliptical, oblique terraces.  
     
     
         5 . The non-cupping cushion of  claim 1  wherein the terraces are formed of elastic material with a durometer strength selected according to the amount of pressure to be applied.  
     
     
         6 . The non-cupping cushion of  claim 1  wherein the upper terrace includes a cavity.  
     
     
         7 . The non-cupping cushion of  claim 1  wherein the at least one lower terrace includes a cavity.
