An article comprises a cushioning assembly that comprises a first bladder element forming a first fluid chamber. The cushioning assembly further comprises a second bladder element within the first bladder element. The second bladder element forms a second fluid chamber sealed from and within the first fluid chamber. At least one reinforcement element is operatively connected to and in contact with at least one of the first bladder element and the second bladder element. The at least one reinforcement element is configured to reinforce the cushioning assembly under a load applied to the first bladder element. A method of manufacturing an article with the cushioning assembly is provided.

A sole structure for a shoe that can secure cushioning properties and obtain a ground surface information is disclosed. The sole structure includes a first midsole having a plurality of first protrusions on a foot-sole-contact side, an outsole having a plurality of second protrusions on a ground surface side, and a second midsole disposed at a part of a region between the first midsole and the outsole and having a lower compressive rigidity than the first midsole. At least a part of the plurality of first protrusions of the first midsole is located at a position corresponding vertically to at least a part of the plurality of second protrusions of the outsole.

An outsole includes a substantially flat reference surface formed on a lower side of the outsole, and studs projecting downward from the reference surface and each having a projection surface positioned below the reference surface. Midsole hollows are provided in a lower portion of a midsole. The midsole hollows are each defined between an upper portion of the outsole and an associated one of midsole recesses formed in a lower surface of a lower midsole at positions facing upper sides of the studs.

The present invention is directed toward cushioning for a sole structure for an article of footwear. The cushioning is three-dimensionally (3D) printed cushioning formed from a plurality of cells. Each cell in the plurality of cells includes a lattice of elongate structures that extend symmetrically around an offset axis. The elongate structures of adjacent cells in the plurality of cells connect so that the plurality of cells form a unitary structure and, as the elongate structures of each cell are compressed by a compressive force, the elongate structures of each cell create a lateral shear. As the compressive force is released, the elongate structures return to a rest position, exerting a restorative force on the insole and/or upper of an article of footwear in which the cushioning is included.

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 comprises a midsole including a first cushioning layer, a second cushioning layer, and a third cushioning layer. The first cushioning layer has a central portion, and a peripheral portion surrounding the central portion. The first cushioning layer, the second cushioning layer, and the third cushioning layer are stacked with the second cushioning layer directly overlying the peripheral portion of the first cushioning layer, and the third cushioning layer overlying the second cushioning layer and directly overlying the central portion of the first cushioning layer. The first cushioning layer has a domed lower surface extending away from the second cushioning layer and the third cushioning layer and substantially centered under the central portion.

A sole structure for an article of footwear comprises a sole plate that has a foot-facing surface with a forefoot portion, and a ground-facing surface opposite from the foot-facing surface. The sole plate has a plurality of grooves extending at least partially transversely relative to the sole plate in the forefoot portion of the foot-facing surface, and a plurality of ribs protruding at the ground-facing surface, extending at least partially transversely relative to the sole plate, and underlying the plurality of grooves. At least some grooves of the plurality of grooves are configured to be open when the sole structure is dorsiflexed in a first portion of a flexion range, and closed when the sole structure is dorsiflexed in a second portion of the flexion range that includes flex angles greater than in the first portion of the flexion range.
