Reusable custom insoles

Abstract

A reusable, customizable shoe-insole having malleable support material configured to assume a first arch-support structure and a first metatarsal-support structure responsively to application of foot pressure of a first user and maintain the first arch-support structure and the first metatarsal-support structure during the absence of foot pressure and assume a new arch-support structure and a new metatarsal-support structure responsively to each new application of foot pressure of additional users.

What is claimed is: 
     
         1 . A custom, reusable shoe insole comprising:
 an insole base; and   a malleable, arch-support material supported by the insole base, the arch-support material configured to assume a first arch-support structure responsively to application of foot pressure of a first user on the arch-support material and to maintain the first support-structure until foot pressure of a second user is applied to the first arch-support structure,   wherein the arch support-structure corresponds to arch geometry between a heel bone and at least one metatarsal head of each of the first and second users.   
     
     
         2 . The custom reusable shoe insole of  claim 1 , wherein the arch-support material is disclosed inside an airtight polymeric encasement. 
     
     
         3 . The custom reusable shoe insole of  claim 2 , wherein the arch-support material has a mass of about 15 to 25 grams 
     
     
         4 . The custom reusable shoe insole of  claim 2 , wherein the arch-support material includes malleable clay. 
     
     
         5 . The custom reusable shoe insole of  claim 4 , wherein the arch-support material includes polydimethylsiloxane. 
     
     
         6 . The custom reusable shoe insole of  claim 2 , wherein the polymeric encasement is constructed from a polymer selected from the group consisting of polyvinyl chloride, polypropylene, and polyethylene. 
     
     
         7 . The custom reusable shoe insole of  claim 2 , further comprising a padding layer covering the encasement. 
     
     
         8 . A custom, reusable shoe insole further comprising:
 a malleable, metatarsal-support material supported by the insole base, the metatarsal-support material configured to assume a first metatarsal-support structure responsively to application of the foot pressure of the first user on the metatarsal-support and to maintain the first metatarsal-support structure until foot pressure of the second user is applied to the first metatarsal-support structure.   
     
     
         9 . A method of constructing a custom, reusable shoe insole, the method comprising:
 providing an insole base; and   causing a malleable arch-support material to be supported by the insole base so as to enable the arch-support material to assume a first customized arch-support structure responsively to application of foot pressure of a first user on the arch-support material and to maintain the first customized arch-support structure until foot pressure of a second user is applied to the first arch-support structure,
 wherein the first customized arch-support structure is bound in part by a heel bone and at least one metatarsal head. 
   
     
     
         10 . The method of  claim 9 , wherein the arch-support material is disclosed inside an airtight polymeric encasement. 
     
     
         11 . The method of  claim 9 , wherein the arch-support material has a mass of about 30 to 40 grams. 
     
     
         12 . The method of  claim 11 , wherein the arch-support material includes malleable putty. 
     
     
         13 . The method of  claim 12 , wherein the arch-support material includes polydimethylsiloxane. 
     
     
         14 . The method of  claim 11 , wherein the polymeric encasement is constructed from a polymer selected from the group consisting of polyvinyl chloride, polypropylene, and polyethylene. 
     
     
         15 . The method of  claim 11 , further comprising:
 causing a malleable metatarsal-support material to be supported by the insole base so as to enable the metatarsal-support material to assume a first customized metatarsal-support structure responsively to application of the foot pressure of a first user on the metatarsal-support material and to maintain the first customized metatarsal-support structure until foot pressure of the second user is applied to the first metatarsal-support structure.   
     
     
         16 . The custom reusable shoe insole of  claim 15 , further comprising a padding layer covering the encasement. 
     
     
         17 . The custom reusable shoe insole of  claim 16 , wherein the padding layer includes slow rebound foam.
