A material is disclosed herein that may include a plurality of chambers. A wall, a bottom surface, and a top surface may define a chamber. The wall may have a top portion and a bottom portion where the top portion may be adjacent to the top surface, and the bottom portion may be adjacent to the bottom surface. The wall may include an elastic material, and an aerogel powder or an aerogel foam may be disposed within the chamber. This material can be incorporated into clothing and shoes, for example.

A method of making a midsole for an article of footwear includes forming a plurality of foam layers, arranging the plurality of foam layers in a mold to form the midsole, piercing the plurality of foam layers with pins, and introducing heat with the pins to bond the plurality of layers together.

Foot support systems include a fluid flow control system that facilitates movement of fluid into, out of, and/or within a sole structure and/or article of footwear, e.g., to change and/or control pressure in fluid filled bladder(s). Aspects of this technology may relate to one or more of: (a) footwear structures in which such systems are incorporated; (b) valve stem based fluid flow transfer systems; (c) solenoid based fluid flow transfer systems; (d) user input button features; (e) air filter features; (f) fluid tube to fluid distributor connection features; (g) fluid distributor to footwear connection features; (h) valve position sensor features; (i) valve transmission features; (j) pressure control algorithm features; (k) electronic communication features; (l) system sealing features; and/or (m) pressure sensor mounting features.

A sole assembly for an article of footwear includes a midsole that is formed from at least a bladder and foam midsole component. The midsole has a ground facing surface and a sidewall, and the bladder meets the foam midsole at a component boundary on the sidewall. An etching extends into both the foam midsole and the bladder. The etched channel has a depth into the sidewall of between about 2 μm and about 1000 μm and continuously extends across the component boundary.

A sole structure for an article of footwear includes a chassis and a cushioning arrangement. The chassis includes a recess formed between a first surface and a second surface facing the first surface. The cushioning arrangement includes a first cushioning element protruding from the first surface and including a first plurality of lobes and a second cushioning element protruding from the second surface and including a second plurality of lobes contacting the first plurality of lobes. At least one of the first cushioning element and the second cushioning element may include a fluid-filled bladder. A first side of each cushioning element includes a substantially planar base and a second side of each cushioning element includes the lobes formed on an opposite side from the base. The base of each cushioning element is attached to a respective one of the surfaces of the recess.

An article of footwear includes a sole structure having a chassis, an outsole, and a cushioning element. The chassis extending from an anterior end to a posterior end and includes a dock formed between the anterior end and the posterior end. The outsole extends from a first end removably coupled to the anterior end of the chassis to a second end removably coupled to the posterior end of the chassis. The cushioning element is disposed between the chassis and the outsole and includes a first portion removably engaged with the dock of the chassis. The sole structure may include a carriage removably disposed between the chassis and the outsole adjacent to the cushioning element. The carriage includes an upper frame receiving and surrounding the dock and a lower frame receiving and surrounding a portion of the outsole.

A sole structure for an article of footwear having an upper includes an outsole, a plate disposed between the outsole and the upper, and a first cushioning layer. The plate includes an anterior-most point disposed in a forefoot region of the sole structure, a posterior-most point disposed closer to a heel region of the sole structure than the anterior-most point, and a concave portion extending between the anterior-most point and the posterior-most point. The concave portion includes a constant radius of curvature from the anterior-most point to a metatarsophalangeal (MTP) point of the sole structure. The MTP point opposes the MTP joint of a foot during use. The first cushioning layer is disposed between the concave portion and the upper.

A plate for an article of footwear includes a substrate, a first strand portion attached to the substrate via first stitching, and a second strand portion disposed on the first layer. The first strand portion includes first segments that each extend between two different locations along the substrate to form a first layer on the substrate. The second strand portion includes second segments that each extend between two different locations along the substrate to form a second layer on the first layer.

Stability footwear (e.g., a pair of therapeutic shoes) may include at least one stabilizing member, stabilizer, and/or outrigger on a lateral (outer or inner) side of a shoe, substantially adjacent to a sole of a shoe. A stabilizer may be positioned proximate a surface on which the sole rests and extending anywhere from a front, substantially a toe, to a heel of a shoe. The stabilizing member, stabilizer, and/or outrigger may reduce undesired foot roll and consequential ankle injuries and/or falls, by providing additional lateral support that does not compromise mobility or performance of the user.

A sole structure for an article of footwear includes a midsole having a footbed extending from a first end to a second end disposed at an opposite end of the midsole than the first end, a first flange extending in a first direction from the first end of the footbed to a first distal end and a second flange extending in a second direction from the second end of the footbed to a second distal end, and an outsole disposed on an opposite side of the midsole than the footbed and extending from the first distal end through a mid-foot region, the outsole including a greater rigidity than the midsole.
