ABSTRACT:
A sport shoe or boot comprises an integral outer shoe including a plurality of shaped portions of at least two different synthetic resin materials, adjacent portions of different synthetic resin materials being interconnected in overlapping transition areas shaped to fit each other. The outer shoe is manufactured by injecting the different synthetic resin materials in plasticized condition and at staggered intervals into a mold cavity at pre-selected portions thereof, permitting the injected synthetic resin materials to harden in the mold cavity to form the integral outer shoe, and removing the outer shoe from the mold cavity.
