A sole structure includes a main body formed of a first material and at least one insert formed of a second material. The main body defines first portion of a ground-engaging surface including a first channel defined by a first segment extending along a first axis and a second segment extending along a second axis transverse to the first axis. The one or more inserts are received in sockets formed in the main body. The at least one insert defines a second portion of the ground-engaging surface and has a second channel including a third segment extending along a third axis parallel to the first axis and a fourth segment extending along a fourth axis transverse to the third axis and substantially parallel to the second axis. One of the first channel and the second channel defines an interface between the main body and the insert.

A sole structure for an article of footwear comprises a midsole system with a plurality of cushioning units, each having multiple cushioning layers configured to work together as a system to absorb a compressive load, such as a dynamic compressive load due to impact with the ground, in stages of progressive cushioning according to the relative stiffness values of the layers. Various midsole systems disclosed include isolated cushioning units, linked cushioning units, sole layers having stanchions interfacing with the midsole system, midsole systems with sole layers having keyed and unkeyed portions overlying a bladder, and midsole systems with vertically-stacked cushioning units disposed in inverted relationship to one another.

An article of footwear with a traction system. The traction system includes a plurality of traction elements of various heights on the outsole that undergo rotation within the penetrated substratum while avoiding damage from digging the surface while walking. The plurality of traction elements has a shortened height at pivot points of a foot and a lengthened height away from the pivot points of the foot.

A sole arrangement for an article of footwear with a gradient depth value is provided. In one aspect of the disclosure, the sole arrangement extending from an end of a posterior area of the sole arrangement to an end of an anterior area of the sole arrangement, wherein the posterior area of the sole arrangement being formed under a heel area and the anterior area of the sole arrangement being formed under a forefoot area of a foot. The sole arrangement having an upper facing surface and a ground engaging surface, wherein the upper facing surface being on an opposite side of the sole arrangement than the ground engaging surface. The sole arrangement having a maximum posterior depth value. The sole arrangement having a maximum anterior depth value. The maximum posterior depth value may be smaller than the maximum anterior depth value by a first margin.

A shoe sole includes a rear bottom surface part and a toe portion. The rear bottom surface part is formed to extend from a rearfoot portion to a midfoot portion and, when the shoe sole is placed on a flat virtual surface, the rear bottom surface part is in contact with the virtual surface. A height of the toe portion from the virtual surface is set to 170% or greater and 250% or less with respect to a thickness dimension in the rear bottom surface part.

Described herein are systems and devices for providing an orthopedic walking brace having a housing and a sole with a curved distal surface. The housing is configured to encompass and immobilize a patient's ankle against flexion. The distal surface of the sole has a posterior region, a mid region, and an anterior region. The posterior region is configured to lie under a heel portion of the patient's foot and has a first anterior-posterior (AP) curvature that increases from a posterior side of the posterior region toward a middle portion of the posterior region and decreases from the middle portion of the posterior region toward the mid region. The mid region is configured to lie under a center portion of the patient's foot. The anterior region is configured to lie under an anterior metatarsal and toe portion of the patient's foot and has a second AP curvature.

A sole includes an outer sole assembly including a plurality of outer sole members spaced apart from each other by a plurality of gaps. In addition, the sole includes a middle sole assembly defining a plurality of grooves, and an intermediate layer comprising an elastomer. The intermediate layer is disposed between the outer sole assembly and the middle sole assembly. The intermediate layer connects the middle sole assembly to the outer sole assembly. The intermediate layer is more elastic than each of the plurality of outer sole members. The intermediate layer is more elastic than the middle sole assembly. At least one of the gaps is vertically aligned with one of the grooves.

A sole arrangement for an article of footwear with a gradient depth value is provided. In one aspect of the disclosure, the sole arrangement extending from an end of a posterior area of the sole arrangement to an end of an anterior area of the sole arrangement, wherein the posterior area of the sole arrangement being formed under a heel area and the anterior area of the sole arrangement being formed under a forefoot area of a foot. The sole arrangement having an upper facing surface and a ground engaging surface, wherein the upper facing surface being on an opposite side of the sole arrangement than the ground engaging surface. The sole arrangement having a maximum posterior depth value. The sole arrangement having a maximum anterior depth value. The maximum posterior depth value may be smaller than the maximum anterior depth value by a first margin.

A sole arrangement for an article of footwear with a gradient depth value is provided.

The sole arrangement having an upper facing surface and a ground engaging surface, wherein the upper facing surface being on an opposite side of the sole arrangement than the ground engaging surface. The sole arrangement having a maximum posterior depth value. The sole arrangement having a maximum anterior depth value. The maximum posterior depth value may be smaller than the maximum anterior depth value by a first margin.

A heel clamp, or posterior component, for an article of footwear is provided. The heel clamp may comprise a posterior component height value measuring a height value from a lowest point under the heel of the foot on an upper facing surface to a top of the posterior component. A lateral component and a medial component of the heel clamp may include a predetermined height value or an extension height value. The lateral component may be extending into or through an area in-between a lateral malleolus bone of the foot and an Achilles tendon of the foot, the medial component may be extending into or through an area in-between a medial malleolus bone of the foot and the Achilles tendon of the foot, and the intermediate component may be extending to an area of an end of a top of a calcaneus bone of the foot.
