An object of the present invention is to provide a sole of a baseball spike shoe that improves a ball speed in a pitching motion. A sole includes a plurality of first protrusions arranged in a forefoot region of a sole body. Each of the first protrusions is formed such that its longitudinal direction extends along a foot width direction in a bottom view. When the plurality of first protrusions are projected on a virtual projection plane as viewed from a front side of the sole body, the sum of projection lengths of the plurality of first protrusions in the foot width direction is 85% or more and 100% or less of a distance of a straight line connecting in the foot width direction a side of the most medial first protrusion to a side of the most lateral first protrusion.

A sole structure that includes at least one auxetic structure and methods of making are disclosed. A sole structure includes a plate, a first cleat, and an auxetic structure. The plate has an upper surface and a lower surface. The first cleat extends from the lower surface, the first cleat having a first height and having a first tip surface. The auxetic structure has an inner surface affixed to the lower surface and having an outer surface. The inner surface is constrained by the lower surface. The outer surface is spaced closer to the lower surface than to the first tip surface.

Cleat structures, e.g., for golf shoes, may include a flat and flexible interior surface and/or a generally disk-shaped perimeter area that includes features to promote in-molding of the cleat to a footwear sole component (e.g., to permanently engage the cleat with an outsole member). Such cleats may provide a flexible and comfortable base, including a low profile, e.g., to enable formation relatively thin and/or flexible footwear sole components. Footwear sole components and articles of footwear that include one or more in-molded cleat structures of this type also are described. Molds used for in-molding procedures and methods of using the molds to make articles with in-molded components (e.g., for making footwear sole structures including one or more in-molded cleats) also are described.

Provided is a shoe that includes a sole that: (i) has a bottom surface that is adjacent to the ground in normal use, and (ii) is comprised of both a base material forming a main structure and individual leather particles attached to the base material on the bottom surface of the sole. The individual leather particles may have a median size within a range of 0.3 to 4.0 millimeters (mm). In addition, or instead, individual second particles made of a material other than leather also are attached to the base material on the bottom surface of the sole.

An article of footwear is disclosed that includes an upper, an outsole, and a midsole. The upper is configured to receive a foot, and the outsole is secured to the upper. The outsole defines a plurality of apertures extending entirely through the outsole. In addition, the outsole has a ground-engaging surface positioned at a first elevation. The midsole is positionable such that a lower surface of the midsole extends into the apertures of the outsole and is exposed by the apertures.

An article of footwear includes a sole system with a carrier member and a plurality of sensory node elements. The sensory node elements are received in recesses of the carrier member and can protrude through to the upper and/or an insole. The sensory node elements push against the foot to increase sensory perception of the surface underlying the sole system.
