Abstract

The invention relates to an outsole (1) for sports shoes (2) comprising nock-type elements arranged in the front sole area (3) and heel area (4), said nock-type elements extending in a conically tapered manner fro the base (6) thereof to the contact surface (7). The aim of the invention is to improve said outsole, in order to enable improved contact of the feet when they are placed on the ground, even when the ground is moderately hard. This is achieved by reducing the height (h_red) of at least one nock-type element (5′) in the sole edge area (12) of the heel area (4) in relation to the average height (h_norm) of the other nock-type elements (5″) in said area.

Claims

1. Outsole (1) for sports shoes (2), in particular football shoes, with studs (5) tapering conically from their base (6) to their contact surface (7) moulded in the front sole region (3) and heel region (4), characterised in that the height (h_red) of at least one stud (5′

) in the sole edge region (12) of the heel region (4) is reduced compared to the average height (h_norm) of the other studs (5″

) in this region.

2. Outsole according to claim 1, characterised in that the studs (5′

) which are reduced in height exhibit a maximum of 60%, preferably a maximum of 30% of the average height (h_norm) of the studs (5″

) which are not reduced in height.

3. Outsole according to claim 1 or 2, characterised in that all the studs (5′

) in the sole edge region (12) of the heel region (4) lying in an angle range (α

) of 30°

to 135°

, preferably 60°

to 120°

of an imaginary circle (8) defining the end region of the heel region (4), are reduced in height.

4. Outsole according to one of claims 1 to 3, characterised in that the base (6) of the moulded studs (5) exhibits an elongated cross-section, in particular a cross-section similar to the shape of an ellipse.

5. Outsole according to one of claims 1 to 4, characterised in that the longitudinal axis (9) of the studs (5) moulded in the sole edge region (12) in the front sole region (3) runs in the direction of the sole edge (12).

6. Outsole according to one of claims 1 to 5, characterised in that the longitudinal axis (9) of the studs (5) moulded in the sole edge region (12) in the heel region (4) runs transversely to the direction of the sole edge (12).

7. Outsole according to one of claims 1 to 6, characterised in that the longitudinal axis (9) of the base (6) of one or more of the inner studs (5′

″

) surrounded by the studs (5) in the sole edge region (12) runs in the direction of the sole longitudinal axis (10).

8. Outsole according to one of claims 1 to 7, characterised in that the height of the studs (5) in the sole edge region (12) of the front sole region (3) is less than the height of the studs (5″

) which are not reduced in height in the sole edge region (12) of the heel region (4).

9. Outsole according to one of claims 1 to 8, characterised in that in the front sole region (3) there are inner studs (5′

″

) which are surrounded by studs (5) in the sole edge region (12), the height of the inner studs (5′

″

) being less than the height of the studs (5) in the sole edge region (12).

10. Outsole according to claim 9, characterised in that in the middle front sole region (3) three or more studs (5′

″

) are arranged next to one another over the sole width (11).

11. Outsole according to claim 9 or 10, characterised in that the studs (5′

″

) arranged next to one another are arranged offset in relation to one another relative to the sole longitudinal axis (10).

12. Outsole according to one of claims 1 to 11, characterised in that the stud contact surface (7) of the studs (5) runs from the sole edge to the sole longitudinal axis (10) with decreasing stud height.
