ABSTRACT:
A toe protector, or a metatarsal protector, or a combined toe and metatarsal protector for safety footwear are molded from plastics material either integrally or separately and then attached to one another for storage and incorporation into the finished footwear. Each part of the respective protector comprises a generally U-shaped body provided at the central part of its top outer surface with two mutually facing, spaced surfaces extending outward therefrom and bounding between them a central part of the top portion. A force receiving plate overlies the respective central part with its lower surface spaced from the central part, is of concave shape toward the central part, and has two spaced edges engageable with the two surfaces. In an integral structure the adjacent surfaces and edges are constituted by corresponding integral junctions. Crushing and impact forces applied to the plate member press it toward the central part with conversion of such crushing and impact forces to corresponding butting forces distributed along the surfaces and compression forces in the sides of the U. The force receiving plate member may comprise a thin molded sheet of plastics material or a thin formed sheet of metal. Each protector body part and force receiving plate member may be divided along its length by transversely extending slots to increase its longitudinal flexibility so as to accommodate the action of walking.
