Abstract

A heel prosthesis is disclosed. In one embodiment, the heel prosthesis comprises a back portion, a bottom portion, a first lateral portion, and a second lateral portion. The back portion, the bottom portion, the first lateral portion, and the second lateral portion form a concave receptacle that is configured to adhere to or clip onto a heel of a person.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A heel prosthesis, comprising:
 a back portion;   a bottom portion;   a first lateral portion; and   a second lateral portion, wherein
 the back portion, the bottom portion, the first lateral portion, and the second lateral portion form a concave receptacle that is configured to adhere to or clip onto a heel of a person. 
   
     
     
         2 . The heel prosthesis of  claim 1 , wherein the back portion has a thickness profile that causes the back portion to bulge outwards from the concave receptacle. 
     
     
         3 . The heel prosthesis of  claim 1 , wherein the first lateral portion has a thickness profile that causes the first lateral portion to bulge outwards from the concave receptacle. 
     
     
         4 . The heel prosthesis of  claim 1 , wherein the second lateral portion has a thickness profile that causes the second lateral portion to bulge outwards from the concave receptacle. 
     
     
         5 . The heel prosthesis of  claim 1 , wherein the heel prosthesis is made of at least one of a polysiloxane, a polymer, or a polyamide. 
     
     
         6 . The heel prosthesis of  claim 5 , wherein a surface of the concave receptacle is lined with an adhesive material. 
     
     
         7 . The heel prosthesis of  claim 6 , wherein the adhesive material is one of a pressure-sensitive adhesive, a heat-activated adhesive, or a moisture-activated adhesive. 
     
     
         8 . The heel prosthesis of  claim 6 , wherein the adhesive material is at least one of removable, reusable, or washable. 
     
     
         9 . The heel prosthesis of  claim 1 , wherein an overall thickness of the first lateral portion is greater than an overall thickness of the second lateral portion. 
     
     
         10 . The heel prosthesis of  claim 1 , wherein an overall thickness of the first lateral portion is smaller than an overall thickness of the second lateral portion. 
     
     
         11 . An article of footwear, comprising:
 a back portion;   a bottom portion;   a first lateral portion; and   a second lateral portion, wherein
 the back portion, the bottom portion, the first lateral portion, and the second lateral portion form a concave receptacle that is configured to adhere to or clip onto a heel of a person. 
   
     
     
         12 . The article of footwear of  claim 11 , wherein the back portion has a thickness profile that causes the back portion to bulge outwards from the concave receptacle. 
     
     
         13 . The article of footwear of  claim 11 , wherein the first lateral portion has a thickness profile that causes the first lateral portion to bulge outwards from the concave receptacle. 
     
     
         14 . The article of footwear of  claim 11 , wherein the second lateral portion has a thickness profile that causes the second lateral portion to bulge outwards from the concave receptacle. 
     
     
         15 . The article of footwear of  claim 11 , wherein the article of footwear is made of at least one of a polysiloxane, a polymer, or a polyamide. 
     
     
         16 . The article of footwear of  claim 15 , wherein a surface of the concave receptacle is lined with an adhesive material. 
     
     
         17 . The article of footwear of  claim 16 , wherein the adhesive material is one of a pressure-sensitive adhesive, a heat-activated adhesive, or a moisture-activated adhesive. 
     
     
         18 . The article of footwear of  claim 16 , wherein the adhesive material is at least one of removable, reusable, or washable. 
     
     
         19 . The article of footwear of  claim 11 , wherein an overall thickness of the first lateral portion is greater than an overall thickness of the second lateral portion. 
     
     
         20 . The article of footwear of  claim 11 , wherein an overall thickness of the first lateral portion is smaller than an overall thickness of the second lateral portion.
