ABSTRACT:
In the injection molding of plastic boots, a reinforced arch and heel construction is disclosed wherein a reinforced insole member, of comparatively rigid material formed in a single piece with a rigid heel portion, is incorporated into the two step process of molding the upper portion and then the sole portion of the boot. In one embodiment the reinforced member is molded to the boot upper during the first step of the molding process, and in an alternative embodiment the reinforcement member is incorporated into the boot during the second step of the molding process. A third simpler embodiment utilizes a conventional wood screw as the heel portion of the reinforcement member, and the member may be inserted after molding of the boot.
