Abstract

In safety footwear, an impact-resistant toe-cap, for example of steel, has a synthetic plastics coating by means of which it is secured to the shoe. The coating, which can incorporate a base board, has a lip which is stitched to the upper. The coating may form a peripheral flange for incorporation in a stitched welt. The coating protects the wearer against head edges of the toe-cap and protects a steel toe-cap against corrosion.

Claims

1. Safety footwear having an upper, a sole and an impact-resistant toe-portion, the said toe-portion comprising a rigid toe-cap, a toe-cap lining, an outer toe-cap cover and a flexible lip extending beyond the rear edge of the rigid toe-cap;

the toe-cap lining, the outer cover and the flexible lip being formed of synthetic plastics material as a single unit to completely enclose the rigid toe-cap in a coating of the said plastics material bonded to the toe-cap;

the toe-portion being attached by means of the flexible lip to the upper and the toe-portion being secured to the front of the sole.

2. Safety footwear as claimed in claim 1 in which the upper has an edge attached to the lip and does not cover the body of the toe-cap.

3. Safety footwear as claimed in claim 2 in which the lip is stitched to the upper.

4. Safety footwear as claimed in claim 2, 3 or 1 in which the toe-cap includes an integral base part.

5. Safety footwear as claimed in claim 4 in which the coating is in the form of a moulded unit with a peripheral flange which is fastened in the welt of the footwear.

6. Safety footwear as claimed in claim 1 further comprising a base-board, said base-board being enclosed by the coating to form an integral unit with the toe-cap.

7. Safety footwear as claimed in claim 3, 6 or 1 in which said coating is formed as a moulded unit and has a peripheral flange, said flange being fastened in the welt of the footwear.

8. Safety footwear as claimed in claim 1 in which the toe-cap is of metal.
