Abstract:
1. A method of manufacturing footwear comprising the steps of: inserting a rubber sheet into a mold, placing to layer a first adhesive film on the rubber sheet, and pressurizing the layered rubber sheet and first adhesive film to mold an outsole in the mold; inserting the molded outsole into a phylon mold for molding a midsole, placing to layer a second adhesive film on the first adhesive film of the outsole, placing to layer an EVA foam on the second adhesive film, placing to layer a third adhesive film on the EVA foam, and pressurizing the layered outsole, first adhesive film, second adhesive film, EVA foam, and third adhesive film to form and manufacture a shoe sole in the phylon mold; and bonding the shoe sole and an upper with each other using the third adhesive film bonded on the surface of the midsole, wherein the first and second adhesive films comprise: one composite selected from rubber series material, olefin series material, and rubber-based thermo plastic elastomer; one composite selected from polyethylene-based coupling agent and ethylene vinyl acetate-based coupling agent; and montane wax, and fatty acid esters with pentaery thritol having five to nine carbons.
