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 simplified sole structure for a baseball spiked shoe can improve cushioning properties of a heel region of the sole structure and can enhance comfort when wearing the shoe. The baseball spiked shoe includes a first midsole of a soft elastic member that is disposed at a heel central portion of the shoe, a second midsole of a soft elastic member that is disposed around and outwardly e.g. horizontally away from the first midsole via a circumferential groove therebetween and that is integrated with or unitary as one unit with the first midsole, and an outsole plate of a hard elastic member that is disposed on lower surfaces of the first and second midsoles, that has a plurality of spikes fitted thereon, and that has a hardness greater than a respective hardness of each of the first and second midsoles.

An insole having a top sheet and a base layer with three pieces that include a base layer, a forefoot pad and a midfoot-to-heel support cushion. The mid-foot/heel surface has a raised medial arch and longitudinal curvilinear indentations, a flattened mid-foot area with a metatarsal mid-foot tear-drop raised area, and a surrounding the heel pod that cups the exterior back by a heel cup. A heel pad opening goes through the entirety of the thickness of base layer of the insole body and a heel pad is affixed to the bottom surface of the base layer. There is also a supersoft heel dome and a metatarsal raised dome on the top (foot contact) surface of the insole which would be directly above the heel pod and the metatarsal midfoot area, respectively.

An insole having a top sheet and a base layer with three pieces that include a base layer, a forefoot pad made of a clear TPR gel and a mid-foot to heel cushion made of a supersoft polyurethane. The midfoot/heel surface has a raised arch with criss-crossing longitudinal curvilinear indentations, a flattened midfoot area with a metatarsal midfoot tear-drop raised area, and a heel cup that surrounds the exterior back of the heel. A heel pod opening goes through the entirety of the thickness of base layer of the insole body and a heel pad is affixed to the bottom surface of the base layer being made of a clear TPR gel or blown EVA. There is also a supersoft heel dome and a metatarsal raised dome on the top (foot contact) surface of the insole which would be directly above the heel pod and the metatarsal midfoot area, respectively.

A shoe can include support members for a plantar surface of a foot that include: (a) a heel support plate; (b) a forefoot support plate; (c) a heel securing strap component for securely engaging a heel supporting component with a wearer's heel; and (d) a unidirectional hinge, wherein the hinge allows the heel support plate to rotate internally with respect to the forefoot support plate and limit the heel support plate from rotating externally with respect to the forefoot support plate. The support member allows the shoe to twist and move with the foot, allowing the ankle to remain neutral, rather than the shoe fighting the foot's natural motion. The unidirectional nature of the hinge plate also prevents the shoe from rotating externally beyond a predetermined limit point.

A sole structure for a shoe that can reduce the burden of MP joints and a knee joint of a shoe wearer's foot during running and that can improve cushioning properties. The sole structure of the shoe includes an upper plate of a hard elastic member disposed at a forefoot region of the shoe, a lower plate of a hard elastic member disposed under and spaced away from the upper plate, and a midsole of a soft elastic member interposed between the upper plate and the lower plate. The midsole has a longitudinally extending hollow portion that is upwardly concavely curved at a lateral mid-portion of the midsole. The lower plate has a concave portion corresponding to the hollow portion of the midsole.

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.
