An outsole for an article of footwear includes a plantar surface and a peripheral surface surrounding the plantar surface. The outsole for an article of footwear also includes an annular cleat set including a first plurality of traction elements arranged in series about a central axis on the plantar surface. The outsole for an article of footwear further includes one or more radial cleat sets each including a second plurality of the traction elements aligned along a respective radial axis intersecting the central axis. At least one of the second plurality of the traction elements includes a peripheral cleat formed on the peripheral surface.

A separable footwear article may comprise an outsole oriented at the bottom of the footwear and configured for ground contact, the outsole comprising a first material; an upper portion releasably coupled to the outsole with thread using chain stitching, the upper portion comprising a second material different from the first material; and an insole removeably disposed adjacent the upper portion and the outsole, the insole comprising a third material different from the first material and the second material; wherein the outsole, the upper portion, and insole are capable of being separated by releasing the thread and hand pulling the thread from the footwear article.

An article of footwear includes an upper and a plate having a top surface facing the upper and a bottom surface formed on an opposite side than the top surface, the plate extending from a first end in a forefoot region to a second end in a heel region. A first cushioning element is attached to the bottom surface of the plate in the forefoot region and a second cushioning element is attached to the bottom surface of the plate in the heel region, the second cushioning element being separated from the first cushioning element by a first gap formed in a mid-foot region. One or more fluid-filled bladders are each at least partially surrounded by the first cushioning element in the forefoot region and have a top surface attached to the bottom surface of the plate.

A reinforcement device reinforcing an upper includes: a rear first portion placed between a sole and a top line in a rear end portion of the upper; a rear second portion placed in a boundary portion between the upper and the sole in the rear end portion of the upper; a lateral first portion being continuous with the rear first portion and extending toward the sole on the lateral side; a medial first portion being continuous with the rear first portion and extending toward the sole on the medial side, the medial first portion being less flexurally deformable than the lateral first portion; and a medial second portion being continuous with the rear second portion and extending toward an anterior direction from the rear second portion along the medial side boundary portion so that the medial side boundary portion is less flexurally deformable than the lateral side boundary portion.

A device configured to surround a portion of a foot-receiving cavity at a heel region of an article of footwear comprises a control bar having a center segment, a first side arm extending from the center segment, and a second side arm spaced from the first side arm and extending from the center segment. The control bar may include a series of slats. A base supports the control bar and is connected to the first side arm and the second side arm. The control bar is biased to an unstressed position with the center segment a first distance from the base, and elastically bends under an applied force to a loaded position with the center segment a second distance from the base less than the first distance. The device stores potential energy that returns the control bar to the unloaded position upon removal of the applied load.

A sole structure includes an outsole defining an inner outsole surface and an outer outsole surface opposite the inner outer surface. The inner outsole surface is spaced apart from the outer outsole surface along a first direction. The sole structure further includes a midsole disposed on the outsole and a footwear plate is directly coupled to the midsole. The footwear plate includes a composite material and includes a first plate portion, a second plate portion is connected to the first plate portion, and a third plate portion is connected to the second plate portion. The second plate portion is connected between the first plate portion and the third plate portion. The second plate portion is obliquely angled relative to the first plate portion and the third plate portion so that the first plate portion is spaced apart from the third plate portion along the first direction.

A sole structure including a midsole, an outsole, and a plate disposed between the plate and the outsole. The plate includes a first portion having an arcuate shape extending through a forefoot region and a mid-foot region, and a planar second portion connected to the first portion along a joint and extending in a first plane at an oblique angle from the joint. The plate includes a first channel extending from a first end of the plate along the first portion and in a direction toward the second portion. A second channel extends from a second end of the plate along the second portion and in a direction toward the first portion. The first channel separates the plate into a first pair of tabs formed at the first end and the second channel separates the plate into a second pair of channels formed at the second end.
