Removable footwear insert

Abstract

A removable puncture protective footwear insert with an insole with an orthotic shape that includes an arch support and a heel cup made of a cellular foam product, a multiple layer protective material where the layers are coupled together and held within the insole and a cushioning and shock absorption material that helps maintain the insole orthotic shape. The cellular foam product is PORON™ or ethylene vinyl acetate, PORON™ and ethylene acetate and the insole may be with or without a tile heel cup. The multiple layer protective material is a SWEN-FLEX® material LENZI EGISTO PS5 ES L-PROTECTION® material, or other puncture proof material. There are also two or more separate methods for manufacturing a removable footwear insert.

 an insole that includes an arch support, said insole is made of a cellular foam product that covers an entire bottom of a user's foot;   a multiple layer protective material with a plurality of layers, wherein said layers may be coupled together and held within said insole; and   a cushioning and shock absorption material that helps maintains an insole shape.   
     
     
         2 . The insert according to  claim 1 , further comprising a heel cup. 
     
     
         3 . The insert according to  claim 1 , wherein said cellular foam product is ethylene vinyl acetate. 
     
     
         4 . The insert according to  claim 1 , wherein said multiple layer protective material is a fabric. 
     
     
         5 . The insert according to  claim 1 , wherein said multiple layer protective material is a puncture proof material. 
     
     
         6 . The insert according to  claim 5 , wherein a thermoplastic hot melt film adhesive couples said insole, said multiple layer protective material, said puncture proof material, said cambrelle material and said cushioning and shock absorption material together. 
     
     
         7 . The insert according to  claim 1 , wherein a second adhesive couples said insole, said multiple layer protective material, said puncture proof material, said TC cotton material or cambrelle material and said cushioning and shock absorption material. 
     
     
         8 . The insert according to  claim 7 , wherein said second adhesive is heat activated. 
     
     
         9 . The insert according to  claim 8 , wherein said second adhesive is heat activated in the range of 140 and 400 degrees Fahrenheit. 
     
     
         10 . The insert according to  claim 1 , wherein said cushioning and shock absorption material is made of open cell urethane. 
     
     
         11 . A removable puncture protective footwear insert, comprising:
 an insole that includes an arch support and a heel cup, said insole is made of a cellular foam product that covers an entire bottom of a user's foot;   a multiple layer protective puncture proof material with a plurality of layers, wherein said layers may be coupled together and held within said insole;   a cushioning and shock absorption material that helps maintain an insole shape; and   a thermoplastic hot melt film adhesive that couples said insole, said multiple layer protective material, said puncture proof material, said cambrelle material and said cushioning and shock absorption material together.   
     
     
         12 . The insert according to  claim 11 , wherein said cellular foam product is ethylene vinyl acetate. 
     
     
         13 . The insert according to  claim 11 , wherein said multiple layer protective material is a fabric. 
     
     
         14 . The insert according to  claim 11 , wherein a second adhesive couples said insole, said multiple layer protective material, said puncture proof material, said TC cotton material or cambrelle material and said cushioning and shock absorption material. 
     
     
         15 . The insert according to  claim 14 , wherein said second adhesive is heat activated. 
     
     
         16 . The insert according to  claim 15 , wherein said second adhesive is heat activated in the range of 140 to 400 degrees Fahrenheit. 
     
     
         17 . The insert according to  claim 11 , wherein said cushioning and shock absorption material is made of an open cell urethane. 
     
     
         18 . The insert according to  claim 11 , wherein the insert is a flat protective insert without an orthopedic insole and without a flat cushion adhered to either side of the insert. 
     
     
         19 . The insert according to  claim 18 , wherein the flat protective insert is a premade orthotic insole. 
     
     
         20 . The insert according to  claim 19 , wherein the insert is made of material selected from the group consisting of polyurethane, rubber, ethylene vinyl acetate, cellular urethane foam or urethane.
