ABSTRACT:
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.
