A sole structure for an article of footwear includes a first plate, a fluid-filled bladder supported on the first plate, and a second plate supported on the fluid-filled bladder with the fluid-filled bladder disposed between the first plate and the second plate. The first plate ascends rearward of the fluid-filled bladder and the second plate descends rearward of the fluid-filled bladder with a posterior portion of the first plate above a posterior portion of the second plate rearward of the fluid-filled bladder. A method of manufacturing footwear sole structures includes assembling sole structures for plural ranges of footwear sizes, each of the sole structures including a fluid-filled bladder with a predetermined inflation pressure that is different for at least two of the plural ranges.

A sole structure for an article of footwear is provided. The sole structure includes an outsole having a ground-engaging surface and an upper surface formed on an opposite side of the outsole than the ground-engaging surface. A first cushion is disposed proximate to a medial side of the sole structure and includes a first fluid-filled chamber attached to the upper surface of the outsole and a second fluid-filled chamber attached to the first fluid-filled chamber and disposed between the first fluid-filled chamber and the upper. A second cushion is disposed proximate to a lateral side of the sole structure and includes a third fluid-filled chamber attached to the upper surface of the outsole and a fourth fluid-filled chamber attached to the third fluid-filled chamber and disposed between the third fluid-filled chamber and the upper. The second cushion is fluidly isolated from the first cushion.

A sole structure for an article of footwear includes a midsole having a top surface and a bottom surface opposite the top surface, the bottom surface including a first recess. A first bladder is disposed within the first recess and a first outsole member is coupled to the midsole and includes a ground-engaging surface having a first traction element and a second traction element. The first traction element is aligned with the first bladder and defines a first height relative to the ground-engaging surface, the second traction element is aligned with the first bladder and defines a second height relative to the ground-engaging surface, the second height being greater than the first height.

An article of footwear including a sole structure attached to an upper defining an internal void configured to receive a foot of a wearer is described. The sole structure includes a sole body portion having a central ridge element located in an aperture in the sole body portion. The central ridge element has a bottom surface configured to contact the ground and move vertically within the aperture. The movement of the central ridge element pushes a top surface of the ridge element attached to a portion of the upper against the foot of the wearer. The central ridge element is arranged approximately centrally between lateral and medial sides in the forefoot region of the sole structure. The central ridge element provide sensory feedback about lateral movement and to the foot of the wearer.

A sole structure for an article of footwear is provided. The sole structure includes an outsole having a ground-engaging surface and an upper surface formed on an opposite side of the outsole than the ground-engaging surface. A first cushion is disposed proximate to a medial side of the sole structure and includes a first fluid-filled chamber attached to the upper surface of the outsole and a second fluid-filled chamber attached to the first fluid-filled chamber and disposed between the first fluid-filled chamber and the upper. A second cushion is disposed proximate to a lateral side of the sole structure and includes a third fluid-filled chamber attached to the upper surface of the outsole and a fourth fluid-filled chamber attached to the third fluid-filled chamber and disposed between the third fluid-filled chamber and the upper. The second cushion is fluidly isolated from the first cushion.

An article of footwear with a sole system includes a sole member and a protruding member assembly. The sole system provides tactile sensation. Protruding members of the protruding member assembly can translate through holes in the sole member to facilitate tactile sensation.

Disclosed herein are various methods and devices for modifying the comfort and performance characteristics of a shoe. In various embodiments, the devices are soles, insole or outsoles, of a shoe comprising one or more shocks. The shocks may be defined by shock cavities positioned within one or more surfaces of a sole. In some embodiments the shock cavity may be configured to receive one or more shock cavity inserts.

A sole structure for an article of footwear is provided. The sole structure includes an outsole having a ground-engaging surface and an upper surface formed on an opposite side of the outsole than the ground-engaging surface. A first cushion is disposed proximate to a medial side of the sole structure and includes a first fluid-filled chamber attached to the upper surface of the outsole and a second fluid-filled chamber attached to the first fluid-filled chamber and disposed between the first fluid-filled chamber and the upper. A second cushion is disposed proximate to a lateral side of the sole structure and includes a third fluid-filled chamber attached to the upper surface of the outsole and a fourth fluid-filled chamber attached to the third fluid-filled chamber and disposed between the third fluid-filled chamber and the upper. The second cushion is fluidly isolated from the first cushion.

Soles for footwear and footwear are disclosed. The sole may include a midsole having a first surface. The sole may additionally include an outsole having a second surface and a plurality of first recesses. The second surface may be attached to the first surface. The first surface and the plurality of first recesses may define a plurality of chambers. One or more chambers of the plurality of chambers may include trapped air. The midsole may further include first protruding portions that extend downwardly from the first surface toward one or more first recesses of the plurality of first recesses.

Extruded components for articles of footwear and methods of making such articles of footwear are disclosed. A carrier can be formed from a first material, the carrier including an attachment surface configured to attach to an upper and a receiving surface having a plurality of receptacles. A second material can be extruded into a plurality of the receptacles to form cushioning elements of a sole.
