Abstract

Cleat structures, e.g., for football shoes, may include: (a) a cleat base; (b) a cleat free end; and (c) a concave side edge and at least two additional side edges extending between the cleat base and the cleat free end. Such cleats may be incorporated into sole structures (e.g., outsole components) that have one or more of: a base plate having a V-shaped support structure with lateral and medial support members extending forward from a base support area located in a heel or rear midfoot area of the outsole component; a base plate having a matrix structure with recesses or openings formed between rib elements that make up the matrix structure; and/or a base plate having a rear heel support. The cleats and base plates may be made, at least in part, as unitary, one-piece constructions, using selective laser sintering or other three-dimensional printing and/or rapid manufacturing additive fabrication techniques.
