Abstract

This invention concerns a sole element for a cleated article of footwear, in particular for a football shoe. The sole element includes a composite element with an anisotropic bending property. The sole element further includes a polymer element, and the polymer element at least partially covers the composite element of the sole element.

First claim

What is claimed is:

1. A sole element for a cleated article of footwear, comprising:
a composite element with an anisotropic bending property; and
a polymer element having a top surface and a bottom surface that is dorsally curved away from a portion corresponding to a ball of a wearer's foot to a toe end such that the bottom surface is convex in a ground facing direction, wherein the polymer element is over-injected onto the composite element and that at least partially covers the composite element,
at least one opening formed in the bottom surface of the polymer element configured to expose at least a part of the composite element, and
wherein the sole element has a first bending stiffness in a first direction and a second bending stiffness that is lower than the first bending stiffness in a second direction, opposite the first direction.

2. The sole element of claim 1 , wherein the first direction comprises an upward direction away from a ground surface and the second direction comprises a downward direction toward the ground surface.

3. The sole element of claim 1 , wherein the polymer element comprises a polyamide.

4. The sole element of claim 1 , comprising a forefoot region, a midfoot region, and a heel region, wherein the composite element is arranged only in the forefoot region.

5. A shoe comprising:
the sole element of claim 1 ; and
an upper attached to the sole element.

6. The sole element according to claim 1 , wherein the polymer element comprises at least one stud dome for carrying a stud tip, wherein the stud dome and the stud tip do not overlap with the composite element.

7. The sole element according to claim 1 , wherein the polymer element is over-injected over the composite element.

8. The sole element according to claim 1 , further comprising an insole board that is attached to the polymer element.

9. The sole element according to claim 1 , wherein the sole element and/or the composite element comprise a non-linear bending stiffness.

10. The sole element according to claim 1 , wherein a rear portion of the composite element is wider than a front portion of the composite element.

11. The sole element according to claim 1 , wherein the composite element further comprises a slit, wherein the slit is arranged substantially along a longitudinal direction of the sole element.

12. A shoe comprising a sole element according to claim 1 .
