A sole structure for an article of footwear includes a plate made of a polymeric material and a plurality of cleats each made of a metallic material. Each of the cleats is overmolded onto the plate. Each of the cleats includes an internal portion and an external portion coupled to the internal portion. The external portion is disposed outside the plate. The internal portion is disposed inside the plate. The internal portion includes a lattice framework. The lattice framework defines a plurality of holes. The plate partly extends through the holes of the lattice framework to secure the plurality of cleats to the plate.

Ground-engaging components for articles of footwear include: (a) an outer perimeter boundary rim that at least partially defines an outer perimeter of the ground-engaging component, wherein the outer perimeter boundary rim defines an open space at least at a forefoot support area of the ground-engaging component, wherein the outer perimeter boundary rim is shaped such that the outer perimeter of the ground-engaging component tapers or curves inward moving from a forefoot support area to an arch support area, and wherein a narrowest dimension from a lateral side edge to a medial side edge of the outer perimeter boundary rim is located in a heel support area of the ground-engaging component; and (b) a support structure extending into or at least partially across the open space. The ground-engaging component may have a narrower width dimension in a central heel or rear heel support area than in the arch support area.

Ground-engaging components for articles of footwear include: (a) an outer perimeter boundary rim that at least partially defines an outer perimeter of the ground-engaging component, wherein the outer perimeter boundary rim defines an upper-facing surface and a ground-facing surface opposite the upper-facing surface, wherein the outer perimeter boundary rim defines an open space at least at a forefoot support area of the ground-engaging component; and (b) a matrix structure extending from the outer perimeter boundary rim (e.g., the ground-facing surface and/or the upper-facing surface) and across the open space at least at the forefoot support area to define an open cellular construction with plural open cells across the open space at least at the forefoot support area, wherein a plurality (e.g., at least a majority) of the open cells have curved perimeters with no distinct corners.

Various embodiments of a system and associated method for a micro-adjustable traction element are disclosed herein. The micro-adjustable traction element system includes an outsole for positioning along a substrate of a shoe. The outsole secures a traction element to the outsole while enabling positional micro-adjustment of the traction element along the outsole. In one embodiment of the micro-adjustable traction element system, for each traction element positioned along the outsole, the outsole includes a receiver element configured for variable positioning within a pocket of the outsole to receive the traction element.

A self-cleaning sport shoe includes a traction member or plurality thereof, extending downward from the bottom of the shoe to traction the playing field surface below upon contact. The self-cleaning sport shoe incorporates a compressible cleaning structure, smaller in size and less cumbersome than existing cleaning type cushions and which is symbiotically mated, when applicable, to a concave reservoir located in the sport shoe outer sole, and in certain instances of design both the outer sole and accommodatingly shaped mid sole as well. As the structure is compressed and expanded, debris that might otherwise remain attached is discarded. This concave reservoir appreciably enhances the cleaning ability of its compressible cleaning structure and the shoe as a whole.

Ground-engaging components for articles of footwear include an outer perimeter boundary rim that at least partially defines an outer perimeter of the ground-engaging component, wherein the outer perimeter boundary rim defines an upper-facing surface and an opposite ground-facing surface. The outer perimeter boundary rim defines an open space at least at a forefoot support area of the ground-engaging component. A matrix structure extends from the outer perimeter boundary rim (e.g., the ground-facing surface and/or the upper-facing surface) and across the open space at least at the forefoot support area to define an open cellular construction with plural open cells across the open space at least at the forefoot support area. The matrix structure defines one or more sets of adjacent open cells, the set(s) including at least three open cells that are substantially aligned in the forefoot support area along a line extending in a forward medial-to-rear lateral direction.

An article of footwear may include an upper, a sole, and a removable cleat member. The sole may include at least one base member disposed in the sole, the base member including a fastener receiving portion, the fastener receiving portion may include at least one female thread. The cleat member may include a cleat body having a ground-engaging end and an opposite fastening end. A fastening portion is configured to extend from the fastening end of the cleat body. The fastening portion may engage with the fastener receiving portion of the base member, the fastening portion including a post and the thread including a draft angle. The thread of the cleat member may be configured to engage with the female thread of the base member.

A traction element arrangement for a sole structure of an article of footwear is described. Traction elements of a first group are associated with a lateral side of the sole structure. Traction elements of a second group are associated with a medial side of the sole structure. Traction elements of the second group include medial rotational traction elements that have a plurality of stud elements arranged in a circular grouping. Stud elements may be aligned laterally across the sole structure with traction elements of the first group. Stud elements may be aligned longitudinally across the sole structure to be arranged in different configurations along an outside medial side or an inside medial side.

An article of footwear (100), apparel (500, 600), and/or sporting equipment (300, 400), and methods of manufacturing thereof, having a hydrogel present on at least a portion of an externally-facing side of the article. The hydrogel is effective in reducing soil accumulation on the article, and/or for reducing soil adhesion to the article.

A traction cleat assembly for a golf shoe includes a hub and removable cover affixed to the hub body in a fixed position with mated sealing engagement between the hub and removable cover defining a, the hub body including a minor driven fitting comprising one of a female fitting and male fitting defined in the hub bottom surface, and the cover top surface including a minor driving fitting for mating engagement with the minor driven fitting to define mated engagement therebetween.
