A laminated waterproof footwear assembly. Where the footwear components are stitched together a gel-like sealant is placed on at least one surface of the footwear components to be joined together. A needle carrying a thread passes through the footwear components carrying the gel with it. The gel dams the hole and forms a waterproof seal.

Sealant system for waterproofing welted footwear

A molded shoe assembly having an outer sole with a heat activatable adhesive coated on one surface and absorbed in the sole surface and a release liner above the adhesive surface. The adhesvie will reactivate at a temperature of between 115 and 125 degrees F.

Film adhesive for sole attaching

A sole assembly is made by placing a release film, having a heat activatable adhesive on one side, in a mold and forming a sole in the mold. The adhesive forms an integral part of the completed sole which allows handling of the molded sole without displacing the adhesive or the release film. The molded sole is used by removing the release film, activating the adhesive and bonding the sole to an upper.

Method for forming a sole having a heat activatable adhesive adhered to

Method for waterproofing a welted footwear construction. The footwear includes an insole rib joined to an insole. The method includes applying a sealant gel to the outer surface of the insole rib and attaching a welt and an upper to the rib by stitching with a needle. The needle carries the sealing gel into and through the needle holes formed thereby forming a water impermeable seal between the welt, the upper and the rib.
