Cleats and footwear for providing customized traction
View Patent ↗A removable cleat includes a plurality of projections, dividing into sets, with each set of projections made of different materials. The cleat includes a coupling element, for attachment to a shoe, and a ground contacting element. The ground contacting element contains a plurality of projections, with the projections divided into at least two sets. The projections may be disposed about the perimeter of the ground contacting element, such that each set of projections does not extend more than half the perimeter. Additionally, some of the plurality of projections may be located interior to the perimeter. Further, each set of projections may be oriented in a particular direction with respect to a plane formed by the perimeter. Each interspersed set of projections may be made of a different material, or each projection may itself be made of a different material.
1. A removable cleat comprising:
a coupling element; and
a ground-engaging element, the ground-engaging element having a perimeter, a first and second side, and a plurality of projections attached to the first side of the ground-engaging element,
wherein the plurality of projections include at least an external set of projections at the perimeter of the ground engaging element, and an internal set of projections substantially internal to the external set of projections,
wherein the external set of projections is made of a different material from the internal set of projections,
wherein the internal set of projections is aligned between every external projection in the external set of projections.
2. The removable cleat according to claim 1 , wherein the different materials have different hardness.
3. The removable cleat according to claim 1 , wherein the internal set of projections includes at least a first set of projections made of a first material and a second set of projections made of a second material, the first set of projections interspersed with the second set of projections.
4. The removable cleat according to claim 3 , wherein the first material is softer than the second material.
5. The removable cleat according to claim 1 , wherein the external set of projections includes at least a first set of projections made of a first material and a second set of projections made of a second material, the first set of projections interspersed with the second set of projections.
6. The removable cleat according to claim 5 , wherein the internal set of projections includes at least a third set of projections made of a third material and a fourth set of projections made of a fourth material, the third set of projections interspersed with the fourth set of projections.
7. The removable cleat according to claim 6 , wherein the coupling element is made of the third material.
8. The removable cleat according to claim 5 , wherein the external set of projections includes a third set of projections made of a third material interspersed with the first set of projections and the second set of projections.
9. The removable cleat according to claim 1 , wherein at least a portion of the external set of projections borders at least a portion of the internal set of projections.
10. The removable cleat according to claim 1 , wherein the external set of projections is a different shape than the internal set of projections.
11. The removable cleat according to claim 1 , wherein the external set of projections is a different size than the internal projections.
12. The removable cleat according to claim 5 , wherein the first material is softer than the second material.
13. The removable cleat according to claim 1 , wherein the different materials are characterized by a different color.
14. The removable cleat according to claim 1 , wherein the internal projections and external projections extend perpendicular to the first side.
15. The removable cleat according to claim 1 , wherein the projections of the external set of projections extend beyond the perimeter.
16. The removable cleat according to claim 1 , wherein the cleat is configured to rotate when attached to a shoe.
17. The removable cleat according to claim 16 , wherein the cleat is able to rotate in only one direction.
