ABSTRACT:
This invention relates to a safety shoe of the type having an upper with a box toe cap in the toe portion thereof and an outer sole of relatively yielding, resilient and flexible material secured to the upper and having a supporting plate of relatively rigid material embedded in and surrounded by the material of the outer sole and having a configuration similar to the generally U-shaped configuration of the lower edge of the safety box toe and being disposed beneath said lower edge in registry therewith so as to impart additional support thereto when a blow or force is applied to the toe cap.
In a preferred embodiment of the invention the supporting plate is formed of a relatively rigid, hard, polymeric material and has a plurality of apertures formed therein into which the material of the outer sole extends to help anchor the supporting plate in position.
