A sole structure for an article of footwear includes a chassis including a footbed having an interior surface and an outer surface formed on an opposite side from the interior surface, the interior surface defining one or more sockets. The sole structure also includes one or more haptic elements each having a bottom surface received within a respective one of the one or more sockets and a top surface protruding from the interior surface of the chassis, each of the one or more haptic elements having a different hardness than the footbed.

A spine for an article of footwear includes a base extending from a first end to a second end. The spine also includes a sidewall extending transversely from the base from the first end to the second end. The sidewall has a plurality of sidewall supports including a forefoot sidewall support at the first end, a heel sidewall support at the second end, and a mid-foot sidewall support disposed between the first end and the second end and defining a maximum height of the sidewall.

The present invention is directed toward an article of footwear having a sole structure effective to increase traction on a support surface. The article of footwear includes a sole structure comprising a first sole structure and a second sole structure. The article of footwear includes a forefoot region, midfoot region, and hindfoot region. The first sole structure is disposed in the forefoot and hindfoot regions. The second sole structure is disposed in the midfoot region. An extension of the second sole structure that extends through the forefoot region is substantially covered by the first sole structure. A plurality of lugs extend downwardly from the bottom surface of the first sole structure. At least one lug extends downwardly from the extension of the second sole structure through the first sole structure. The first sole structure and the second sole structure have different durometers.

There is provided a sole for footwear with a bottom surface comprising: a primary surface and one or more positioning face, wherein: the one or more positioning faces are at an angle to the primary surface; engaging a ground with the primary surface causes a wearer of the footwear to take a natural stance; engaging the ground with the one or more positioning faces causes the wearer to take one or more athletic stances; and the wearer switches between the natural stance and the one or more athletic stances by shifting their weight.

A sole structure for an article of footwear may have a midsole system that includes a sole plate having a forefoot region and a midfoot region. The sole plate may have a foot-facing surface and a ground-facing surface opposite to the foot-facing surface. The sole plate may define a through hole extending from the foot-facing surface to the ground-facing surface in the forefoot region. The through hole may be closer to a medial edge of the sole plate than to a lateral edge of the sole plate. The sole plate may have ridges extending longitudinally in the midfoot region and in the forefoot region. The ridges may have crests at least some of which may extend non-parallel with one another in a longitudinal direction of the sole plate.

A shoe includes a sole and an upper secured to the sole. The sole has an outsole, a molded chassis, a forefoot cushion, and a heel cushion. The medial midfoot region of the outsole is devoid of the outsole such that the chassis member is visible as viewed in a bottom plan view. The molded chassis has a forefoot opening and a heel opening, with both the forefoot opening and the heel opening being through openings extending through the molded chassis. The forefoot opening is in one or more of the toe region and the ball region of the sole, and the heel opening is in the heel region of the sole. The forefoot cushion is in the forefoot opening, and the heel cushion is in the heel opening. The molded chassis is coupled to the outsole and coupled to the upper.

A convertible shoe may include a sole and a plurality of interchangeable heel portions, each selectively attachable to the sole. The heel portions may each include a mounting surface configured to interface with a heel receiver of the sole. The heel receiver may include a fixed hook and a movable hook, with the movable hook being operable by an actuator coupled to a bottom surface of the sole. In some examples, an upper is secured to the sole of the shoe by one or more clamping plates. In some examples, the sole of the shoe is configured to be biased into a default bend corresponding to a high-heeled state even when a low heel is attached to the heel receiver.

A supporting member in a sole for an article of footwear comprising at least a vertical sub-member extending in both a vertical direction and a longitudinal direction that extends along a toe region to a heel region of the sole. Located within or adjacent to a cushioning member, the vertical sub-member has a curvature along the longitudinal direction wherein the curvature is configured to reduce flexion of the cushioning element and/or improve the durability of the supporting member. The supporting member further comprises a horizontal sub-member extending from a sidewall of the vertical sub-member in a latitudinal direction of the sole and being angled away from the vertical sub-member and at least a portion of the vertical sub-member being coextensive with the vertical sub-member.

An article of footwear including an upper and a sole assembly configured to provide broad base structural support and stability to a wearer's foot to promote pain prevention in the wearer. The footwear can include a midsole including a stability bridge that enhances torsional rigidity in an arch region, a bifurcated rigid central shank disposed in the arch region under the stability bridge that is visible to a viewer of the footwear and an outsole disposed below the midsole and the bifurcated central shank. The outsole can include a ladder tread section, disposed below the bifurcated central shank, that less than 5 mm above a lowermost surface of the remainder of the outsole so that the outsole includes a substantially flat ground contacting surface to promote stability. The outsole also can include an upwardly curved rearmost heel strike tread, and heel and/or forefoot impact absorption comfort pods in associated midsole voids.

Sole structures for articles of footwear, including athletic footwear, include a relatively soft and lightweight foam midsole component partially covered by at least one more rigid and/or dense cage (protective) component(s) and/or other protective component(s).
