A cushioning device comprising a sticky surface, the device comprising a gel material bound to a thermoplastic film material having a polarity compatible with the gel material, wherein the thermoplastic film material further comprises a pressure sensitive adhesive located on a surface of the film material opposite to the surface that is bonded to the gel material.

Claims

exact text as granted — not AI-modified
1 .- 58 . (canceled) 
     
     
         59 . A method for providing enhanced adhesion performance of a heel cushioning device in a shoe, which method comprises attaching to the inside of a shoe opposite the heel of a user a polyurethane gel cushioning device comprising an adhesive surface, the device comprising a layer of polyurethane gel material having an upper and lower surface and two layers of thermoplastic polyurethane film material, each layer of said thermoplastic polyurethane film material comprising upper and lower surfaces, wherein the upper surface of the polyurethane gel material is bonded with the lower surface of one of said layers of thermoplastic polyurethane film material and the lower surface of the polyurethane gel material is bonded with the upper surface of the other of said layer of thermoplastic polyurethane film material, wherein at least one of the layers of thermoplastic polyurethane film material comprises a pressure sensitive adhesive on a surface opposite the surface bonded to the polyurethane gel material thereby providing the adhesive surface of the heel cushioning device, wherein the adhesive surface of the heel cushioning device is positioned to attach the heel cushioning device to the inside of the shoe. 
     
     
         60 . The method of  claim 59 , wherein the pressure sensitive adhesive comprises acrylic adhesives, methacrylate adhesives, rubber-based adhesives, 
     
     
         61 . The method of  claim 59 , wherein the pressure sensitive adhesive is an adhesive based on styrene copolymers or silicones and combinations thereof. 
     
     
         62 . The method of  claim 61 , wherein the styrene copolymers comprise styrene-isoprene-styrene (SIS), styrene-ethylene-butylene-styrene (SEBS), styrene-butadiene-styrene (SBS) copolymers with at least one tackifier, or combinations thereof. 
     
     
         63 . The method of  claim 59 , wherein the acrylic adhesive comprises ethylene ethyl acrylate (EEA), ethylene methyl acrylate (EMA) copolymers, or combinations thereof. 
     
     
         64 . The method of  claim 59 , wherein the pressure sensitive adhesive has a thickness of between about 0.0125 mm and about 0.25 mm. 
     
     
         65 . The method of  claim 59 , wherein the polyurethane gel material has a Shore 00 hardness of between about 10 and about 80 
     
     
         66 . The method of  claim 59 , wherein the polyurethane gel material has a Shore 00 hardness of between about 30 and about 60. 
     
     
         67 . The method of  claim 59 , wherein the polyurethane gel material has a Shore 00 hardness of Shore 00 hardness of about 50. 
     
     
         68 . The method of  claim 59 , wherein the polyurethane gel material has a thickness of between 0.3 and 3 mm. 
     
     
         69 . The method of  claim 59 , wherein the thermoplastic polyurethane film material has a Shore A hardness of between about 40 to about 95. 
     
     
         70 . The method of  claim 59 , wherein the thermoplastic polyurethane film material has a thickness of between 0.025 mm and 0.25 mm. 
     
     
         71 . The method of  claim 59 , wherein said thermoplastic polyurethane film material has a thickness of at least 0.025 mm. 
     
     
         72 . A method for providing enhanced adhesion performance of a cushioning device in a shoe, comprising providing a cushioning device comprising a gel material comprising top and bottom surfaces and at least one layer of thermoplastic film material comprising a top and bottom surface bonded to one or both of said top and bottom surfaces of said gel material, wherein at least one of said at least one layer of thermoplastic film material comprises a pressure sensitive adhesive opposite to the surface contacting said gel material thereby providing an adhesive surface of the cushioning device, wherein the adhesive surface of the device is positioned so as to attach the device to the inside of the shoe. 
     
     
         73 . The method of  claim 72 , wherein the gel material is a polyurethane gel material. 
     
     
         74 . The method of  claim 72 , wherein the thermoplastic film material is a polyurethane material. 
     
     
         75 . The method of  claim 72 , wherein the gel material is SEBS gel material. 
     
     
         76 . The method of  claim 72 , wherein the thermoplastic film material is SEBS material. 
     
     
         77 . The method of  claim 72 , wherein the pressure sensitive adhesive comprises acrylic adhesives, methacrylate adhesives, rubber-based adhesives, 
     
     
         73 . The method of  claim 72 , wherein the pressure sensitive adhesive is an adhesive based on styrene copolymers or silicones and combinations thereof. 
     
     
         74 . The method of  claim 73 , wherein the styrene copolymers comprise styrene-isoprene-styrene (SIS), styrene-ethylene-butylene-styrene (SEBS), styrene-butadiene-styrene (SBS) copolymers with at least one tackifier, or combinations thereof. 
     
     
         75 . The method of  claim 72 , wherein the acrylic adhesive comprises ethylene ethyl acrylate (EEA), ethylene methyl acrylate (EMA) copolymers, or combinations thereof.
