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. Further, a directional cleat may include sets of projections interspersed on different parts of the cleat, with each set made of different materials. Such materials may also be of different colors, to help ensure correct installation of the directional cleat on a shoe.
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 at the perimeter of the ground engaging element, wherein the projections include 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,
wherein each of the first set of projections and the second set of projections includes at least one projection oriented substantially perpendicular to the first side and at least one projection not substantially perpendicular to the first side, and wherein the coupling element is attached to the second side.
2. The removable cleat according to claim 1 , wherein a contiguous portion of the perimeter does not include a projection not substantially perpendicular to the first side and includes at least one projection from the first set and at least one projection from the second set, the contiguous portion being more than half the perimeter in length.
3. The removable cleat according to claim 1 , wherein the projections include several projections angled outwardly and extending beyond the perimeter of the ground-engaging element, wherein a contiguous portion of the perimeter does not include a projection not substantially perpendicular to the first side and includes at least one projection from the first set and at least one projection from the second set, the contiguous portion being more than half the perimeter in length.
4. The removable cleat according to claim 3 , wherein the first set of projections is longer than the second set of projections.
5. The removable cleat according to claim 4 , wherein the first material is softer than the second material.
6. The removable cleat according to claim 5 , wherein the removable cleat further includes a third material that possesses a different characteristic from the first and second materials.
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 1 , wherein two of the materials are characterized by a different color, to ease installation of the cleat in the proper direction.
9. The removable cleat according to claim 1 , wherein the first material is softer than the second material.
10. The removable cleat according to claim 9 , wherein the first set of projections is longer than the second set of projections.
11. The removable cleat according to claim 10 , wherein the removable cleat further includes a third material that possesses a different characteristic from the first and second materials.
12. The removable cleat according to claim 11 , wherein the coupling element is made of the third material.
