Midsoles for a sports shoe that comprise a ground facing component comprising a rim portion with a first inward-facing wedge-shaped elongate protrusion and a foot support component arranged slidably at least partially inside the ground facing component. The foot support component may comprise a first outward facing wedge-shaped elongate recess configured to receive the first inward-facing wedge-shaped elongate protrusion of the ground facing component such that the foot support component tilts when sliding towards the rim portion of the ground facing component.

The disclosure describes a spring device for a shoe for arrangement between an insole and an outsole. The spring device comprises a lower outsole portion and an upper insole portion, wherein the lower outsole portion and the upper insole portion are connected to each other via a curvature. At least one section of the curvature has a continuously varying radius of curvature, which increase towards the outsole portion. Both portions may be substantially parallel with respect to each other in a resting state.

An article of footwear defines a lateral side, a medial side, a forefoot region, a midfoot region, and a heel region. The article of footwear includes an upper, a first cushioning member directly coupled to the upper in the heel region, a second cushioning member directly coupled to the upper in the forefoot region, and a plate. The plate is configured as a unitary plate that extends continuously from the forefoot region to the heel region. The plate is directly coupled to each of the upper, the first cushioning member, and the second cushioning member. The plate extends through a gap that is defined between the first cushioning member and the second cushioning member.

An article of footwear includes an upper and a sole structure coupled with the upper. The sole structure defines a forefoot region, a midfoot region that corresponds with a portion of the article of footwear that is configured to encase an arch of a foot, and a heel region that is proximate and adjoining the midfoot region. The footwear also includes a first foam material and a second foam material within the sole structure. The first foam material has a density that is different than a density of the second foam material. At least one of the first and second materials is directly attached to the upper. The footwear further includes a plurality of ground contacting regions and a heel support plate that extends along a portion of the upper in the heel region.

A sole structure for a shoe is provided with a regenerative midsole having an energy storage and release device is provided with a leaf spring assembly movable between a first unloaded position and a second loaded position. A locking linkage cooperates with the leaf spring assembly to lock the leaf spring assembly in the second loaded position. The locking linkage cooperates with the leaf spring assembly so that as the locking linkage is moved to a locked position, the leaf spring assembly is moved to the second loaded position. A trigger is connected to the locking linkage. Actuation of the locking linkage based on a wearer input releases the locking linkage to an unlocked position and allows the leaf spring assembly to move to the first unloaded position and thereby return stored energy to 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.

A sole for a running shoe comprising a sole tip, a heel edge and a midsole having a base surface delimiting the midsole against the vertical direction (V) and a top surface delimiting the midsole in the vertical direction, wherein the midsole has a heel region (FB), a midfoot region (MFB) and a forefoot region (VFB) and an elastic plate. The elastic plate extends at least from the forefoot region into the midfoot region, and in the forefoot region and/or in the midfoot region has a first curvature with a vertex curved along the longitudinal direction (L) of the midsole in the direction of the top surface of the midsole. The elastic plate is formed so the first curvature is elastically bent in the direction of the base surface by the forces acting during treading and/or rolling movement, and the first curvature returns to its original shape during push-off, or wherein the elastic plate in the forefoot region and/or in the midfoot region has a first curvature curved along the longitudinal direction of the midsole in the direction of the base surface of the midsole and having a vertex. The elastic plate is configured such that the first curvature is elastically bent in the direction of the top surface by the forces acting during treading and/or during rolling movement, and the first curvature returns to its original shape during push-off.

An article of footwear that has an upper attached to a sole structure. The sole structure includes a midsole that is positioned between an insole and an outsole. The article of footwear also includes a plate that is removably received within a cavity formed within the midsole. The insole is configured to cover the plate within the cavity. The plate includes a reinforcing member that comprises carbon fiber.

An orthopedic walker is disclosed that improves comfort and shock absorption during use by incorporating a flexure zone that deflects to ease the forces caused by the heel strike portion of a patient's gait. The flexure zone is created by cutting around the heel on the bottom of the sole to allow for the heel portion to flex. The exterior shell of the walker is may be made of a formable resilient material that when combined with an attached tongue structure reduces a volume of encapsulation of the lower limb. The shell encloses a padding on the inner side that may take the form of air/bladders and/or foam, and tabs on each side selectively engage receiving tabs on the inside lateral and medial side of the base upright portions. A separate tongue structure is used to enclose the foot and is made adjustable using various methods such as slits and novel connectors.
