Shock resistant shoe

Abstract

A sole assembly for a shock resistant shoe includes a sole having a heel region and a ball region. A first cone spring, disposed within the sole, includes a large diameter terminal end and an opposing small diameter terminal end. The large diameter terminal end is disposed above the small diameter terminal end.

Having thus described the aforementioned invention, we claim:  
     
         1 . A sole assembly for an article of footwear comprising: 
 a sole having a heel region and a ball region;    a first cone spring disposed within the sole, said first cone spring including a large diameter terminal end and an opposing small diameter terminal end, said large diameter terminal end being disposed above said small diameter terminal end.    
     
     
         2 . A sole assembly in accordance with  claim 1  wherein said cone spring is located in said ball region of said sole.  
     
     
         3 . A sole assembly in accordance with  claim 2  and further comprising a wave spring located in said heel region of said sole.  
     
     
         4 . A sole assembly in accordance with  claim 1  wherein said sole defines a first vacuity and said first cone spring is disposed within the first vacuity.  
     
     
         5 . A sole assembly in accordance with  claim 1  wherein said cone spring is at least partially encapsulated in low density foam.  
     
     
         6 . A sole assembly in accordance with  claim 1  wherein said first cone spring is located in said heel region of said sole.  
     
     
         7 . A sole assembly in accordance with  claim 1  wherein said first cone spring defines a cylindrical axis substantially perpendicular to said sole.  
     
     
         8 . A sole assembly in accordance with  claim 1  and further comprising a second cone spring disposed within the sole, said second cone spring including a large diameter terminal end and an opposing small diameter terminal end, said large diameter terminal end being disposed below said small diameter terminal end.  
     
     
         9 . A sole assembly in accordance with  claim 8  wherein said second cone spring is located in said heel region of said sole.  
     
     
         10 . A sole assembly in accordance with  claim 8  wherein said sole defines a second vacuity and said second cone spring is disposed within the second vacuity.  
     
     
         11 . A sole assembly in accordance with  claim 8  wherein said first cone spring defines a cylindrical axis substantially perpendicular to said sole.  
     
     
         12 . A sole assembly for an article of footwear comprising: 
 a sole having a heel region and a ball region;    at least one cone spring disposed within the sole, said cone spring including a large diameter terminal end and an opposing small diameter terminal end, said large diameter terminal end being disposed above said small diameter terminal end.
