Abstract

In a outsole for sports shoes, each of a multiplicity of tapered anti-slip cleats is provided over its periphery with a plurality of spaced substantially parallel longitudinal ribs. The blunt tread face of each cleat may have an oblique portion, the oblique portions of at least most of the cleats between the heel and shank being inclined forwardly and those of at least most of the cleats between the toe and shank being inclined rearwardly.

Claims

1. An outsole for a sports shoe made from a resiliently deformable material and comprising a multiplicity of deformable frustoconical cleats distributed over the tread side of the outsole and integral therewith, wherein the peripheral surface of the cleats is provided with a multiplicity of axially parallel fine longitudinal ribs and grooves, said ribs and grooves extending over the entire axial length of the cleats.

2. The outsole of claim 1, wherein said cleats are joined to said tread side by a disc-like raised portion.

3. The outsole of claim 2, wherein the fine longitudinal ribs extend up to the circular edge of said disc-like raised portion.

4. The outsole of claim 1, wherein said longitudinal grooves are of constant width.

5. The outsole of claim 1, wherein said cleats have a tread face inclined to the tread side of said outsole.

6. The outsole of claim 5, wherein said tread face of the cleats adjacent the edge of the outsole extends outwardly and upwardly.

7. The outsole of claim 5, wherein the inclined tread faces of at least the majority of cleats at the rear of the outsole up to the shank are inclined forwardly and that of at least the majority of the cleats at the front of the outsole up to the shank are inclined rearwardly.

8. An outsole for a sports shoe made from a resiliently deformable material and comprising a multiplicity of deformable cleats distributed over the tread side of the outsole and integral therewith, the cleats having a base joined to the tread side of the outsole, a peripheral substantially frustoconical face and a tread face, said tread face having a first tread face portion extending substantially parallel to said base, and a second tread face portion extending obliquely toward said base, thereby forming a tip of each cleat of additional deformability.

9. The outsole of claim 8, wherein said cleats adjacent the edge of the outsole have the form of an outwardly directed oblique frustum of a cone.

10. An outsole according to claim 8, wherein the oblique tread face portions of at least the majority of the cleats at the rear of the outsole are inclined forwardly and wherein the oblique tread face portions of at least the majority of the cleats at the front of the outsole are inclined rearwardly.
