Abstract
A rubber footwear product and method of making such products is provided. The rubber footwear product includes a molded rubber midsole having an integrally formed raised rubber welt portion around its periphery. By molding in a compression mold, injection mold, or the like, the midsole and welt may be formed in a variety of designs and will be accurately formed in the desired size and shape. The molded midsole is made of substantially cured rubber, and is secured to an uncured rubber upper by applying an uncured rubber coating onto the midsole and then vulcanizing to form a unitary rubber footwear subassembly. To this subassembly may separately be secured a variety of compositionally different outsoles made of various materials, and having various colors, designs, and specific utilities. The outsole may be attached to the subassembly by vulcanization, by conventional shoemaking cementing processes using adhesive compositions, or by injection molding directly onto the molded midsole.
