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.

A device for use in a shoe includes a first foot, a second foot, a third foot, a fourth foot, a first flexible leg, a second flexible leg, a third flexible leg, and a fourth flexible leg. The first flexible leg extends from the first foot and is curved. The second flexible leg extends from the second foot and is curved. The third flexible leg extends from the third foot and is curved. The fourth flexible leg extends from the fourth foot and is curved. The first flexible leg, second flexible leg, third flexible leg, and fourth flexible leg are joined together with each other at a common area. The first flexible leg, second flexible leg, third flexible leg, and fourth flexible leg are configured to store energy when a force is applied to the common area, and to return energy when the force is removed from the common area.

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.

A shoe sole (1) comprising a stability support plate (3) and a soft elastic midsole (2) having a forefoot area (VFB), a midfoot area (MFB) and a heel area (FB) is disclosed. The stability support plate is peripherally surrounded by the midsole and the midsole (2) has a clear space (21) open to the bottom side (U) of the midsole (2), which is peripherally surrounded substantially completely by the midsole (2) and is delimited by the stability support plate (3). The clear space (21) extends from the heel area (FB) over the midfoot area (MFB) into the forefoot area (VFB) of the midsole (2).

An article of footwear includes an upper and a sole coupled to the upper. The sole includes one or more elongate shape memory components that define a cavity and form a midsole.

A footwear sole structure is provided herein comprising a sole including a heel portion and a forefoot portion and at least one pivot point. Each pivot point is disposed on one of the heel portion and the forefoot portion, and is smaller, in coefficient of friction, than the sole.

A bladder for an article of footwear includes a chamber having (i) an arcuate segment extending from a first transition to a second transition, (ii) a first plurality of elongate segments extending in a first direction from the first transition to a first terminal end, and (iii) a second plurality of elongate segments spaced apart from the first plurality of elongate segments and extending in the first direction from the second transition to a second terminal end. The bladder also includes a web area connecting the arcuate segment, the first plurality of elongate segments, and the second plurality of elongate segments and extending to a terminal edge spaced apart from each of the first terminal end and the second terminal end.
