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. |
