ABSTRACT:
This invention is directed to a mold for injection molding a sole onto an upper made of textile, vinyl, suede, leather, or any other suitable materials in which the lower periphery of the sole slopes downwardly and inwardly and forms a downwardly extending continuation of the peripheral face of the bumper. The mold is capable of using a single sole plate to produce a shoe in which the bumper and integral first sole part is formed of one color, a second sole part is formed of another color and the periphery of the second sole part is visible from the sides and ends of the shoe beneath the bumper. The upper surface of the sole plate of the mold includes an upstanding peripheral fin. The sole plate is capable of producing a skid-resistant surface on the bottom of the second sole part.
