An article of footwear may include a sole structure fixedly attached to an upper defining an internal cavity configured to receive a foot of a wearer. The sole structure may include an exposed outer member configured to contact the ground, the exposed outer member including a first aperture, and a sensory feedback member disposed at least partially within the first aperture in the outer member, the sensory feedback member including a first end and a second end. The first end of the sensory feedback member may include a projection extending through the first aperture and configured to contact the ground. In addition, the second end of the sensory feedback member may include a plurality of flexible bristles extending through a portion of the sole structure and exposed to the internal cavity.

A sole structure for an article of footwear includes a first cushioning element, a second cushioning element, and a panel disposed within a joint formed between the first cushioning element and the second cushioning element. The first cushioning element includes a first surface and a second surface formed on an opposite side from the first surface. The second cushioning element includes a third surface and a fourth surface formed on an opposite side from the third surface. The third surface of the second cushioning element is joined to the second surface of the first cushioning element to form a joint between the first cushioning element and the second cushioning element, where the fabric panel is interposed between the first cushioning element and the second cushioning element within the joint. The panel may be a fabric panel, and more particularly, may include a mesh textile material.

A non-removable insole, that is an integral part of a shoe or other footwear article, includes at least: a top layer, a middle layer, and a bottom layer. The middle layer of the insole has apertures or cavities, that define several discrete storage chambers within the insole. Each storage chamber stores a mixture of two or more particulate materials. The mixture includes one or more materials selected from Group A, which includes natural sand, synthetic sand, artificial sand, kinetic sand, silica, quartz. The mixture further includes one or more materials selected from Group B, which includes: powdered aluminum, powdered titanium, powdered zinc, powdered magnesia, powdered silver, powdered anti-bacterial agent, powdered metal, powdered talcum, grained cork, grained coal, grained wood.

An article of footwear includes a sole structure including a chamber for receiving a pressurized fluid, the chamber having a top portion, a bottom portion, and side portions around a periphery of the chamber. The sole structure also includes a central structure located in a central portion of the chamber between opposing side portions of the chamber, such that the chamber is devoid of additional structures in a surrounding region around the central structure and extending from the central structure to the side portions of the chamber. On all sides of the central structure, a dimension of the surrounding region between the central structure and the nearest side portion is one third or more of a span across the chamber between opposing side portions.

The pressure relieving device is intended to provide users with a stress relieving support surface that is customizable. To that end, the device includes a sleeve with one or more compartments that may be individually filled and refilled with a deformable media. The deformable media further includes a mixture of both non-rigid deformable and rigid non-deformable particles that enable the device to conform to any shape when acted upon by a pressure and recover back when pressure is removed. The device may act as a footwear component for use as a shoe insole insert which may be customized by the user to relieve pain in the areas of foot where most required. Accordingly, the footwear component adapts to the user's foot pattern while standing or moving. Furthermore, the device is durable, washable and reusable, and may be used with open shoes, closed shoes or even without any shoes.

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 metarsophalangeal (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.
