An outsole for a shoe including first and second sole segments that overlap at least partially. The first sole segment can include at least one stud and be arranged at least in a mid-foot portion of the outsole. The second sole segment can include at least one stud and be arranged at least in a toe portion of the outsole. In some embodiments, the outsole can include a first cushion element arranged between the first sole segment and the second sole segment and overlapping with at least one first stud of the first or second sole segment. In some embodiments, the outsole can include a second cushion element being arranged between the first sole segment and the second sole segment and overlapping with at least one second stud of the first or second sole segment. In some embodiments, the outsole may be an outsole for a football shoe.

A sole structure may include chambers and a transfer channel containing an electrorheological fluid. Electrodes may be positioned to create, in response to a voltage across the electrodes, an electrical field in at least a portion of the electrorheological fluid in the transfer channel. The sole structure may further include a controller including a processor and memory. At least one of the processor and memory may store instructions executable by the processor to perform operations that include maintaining the voltage across the electrodes at one or more flow-inhibiting levels at which flow of the electrorheological fluid the through the transfer channel is blocked, and that further include maintaining the voltage across the electrodes at one or more flow-enabling levels permitting flow of the electrorheological fluid through the transfer channel.

A sole structure for an article of footwear comprises a sole plate that has a forefoot portion with a foot-facing surface. The sole plate has at least one groove extending at least partially transversely in the foot-facing surface. The at least one groove is 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.

Presented are footwear sole structures with foot-cushioning insoles movably mounted onto impact-attenuating midsoles, methods for making/using such sole structures, and footwear fabricated with such sole structures. A multilayered sole structure assembly includes an insole movably mounted on a midsole. The midsole is formed with a first compressible material and includes opposing upper and lower midsole surfaces, multiple protrusions projecting from the upper midsole surface, and multiple pockets recessed into the upper midsole surface and interleaved with the midsole protrusions. The insole, which is formed with a second compressible material distinct from the first compressible material, includes opposing upper and lower insole surfaces, multiple protrusions projecting from the lower insole surface and interleaved with the midsole protrusions, and multiple pockets recessed into the lower insole surface and interleaved with the insole protrusions. Each midsole protrusion nests within a respective insole pocket, while each insole protrusion nests within a respective midsole pocket.

Provided is a shoe sole member formed by at least two types of polymer compositions, a first composition and a second polymer composition, including: a first part formed by the first polymer composition; a second part formed by the second polymer composition; and a third part formed by a mixture of the first polymer composition and the second polymer composition between the first part and the second part.

Airsoles or bladders for articles of footwear comprising multi-layered films are provided herein. In one aspect, the airsoles or bladders comprise a first sheet and a second sheet, wherein a first side of the first sheet faces a second side of the second sheet, wherein the first sheet and the second sheet are bonded together to form an internal cavity in a space between the first side of the first sheet and the second side of the second sheet, forming a bladder capable of retaining a gas in the internal cavity at a pressure above atmospheric pressure, at atmospheric pressure, or below atmospheric pressure; and wherein each of the first sheet and the second sheet comprise a multi-layered film comprising: a core region comprising at least 20 gas-barrier layers and a plurality of elastomeric layers, wherein the gas-barrier layers alternate with the elastomeric layers.
