A medical shoe having a plurality of outsole projections is provided. The medical shoe may include a sole assembly configured to support a foot, and a frame surrounding the sole assembly. The sole assembly may include a midsole portion forming a substantially planar surface for supporting the foot and an outsole portion including the plurality of outsole projections extending from the midsole portion. The frame may include a plurality of through holes corresponding to the plurality of outsole projections. The plurality of outsole projections may extend through the plurality of through holes so as to form a ground contacting surface. The plurality of outsole projections may also be provided in a symmetrical pattern. The sole assembly may be secured to the frame by a self-locking fit between the sole assembly and the frame.

Provided is a non-skid shoe capable of absorbing shock including: an outsole; a plurality of accommodation grooves formed on the outsole, the accommodation groove including a groove portion, and a penetrated portion extending from the groove portion and penetrating the outsole; a support member which is accommodated in the respective accommodation grooves, and includes a support portion disposed in the groove portion, a first guide portion formed at a center of the support portion, and a second guide portion extending from the first guide portion and penetrating a bottom surface of the support portion; a movable member which is disposed in the respective support members, and includes a latch portion and a protruding portion; a pressing member engaged to an upper portion of the first guide portion; a resilient member disposed in the first guide portion; and a midsole engaged to the top surface of the outsole.

A footwear sole structure includes a midsole having a ground-facing surface with a forefoot region, a midfoot region, and a heel region. The midsole defines downwardly-extending protrusions at the ground-facing surface distributed over the midfoot region and the heel region, each of the downwardly-extending protrusions having a convex outer surface. A height of the midsole is greatest at the midfoot region. The sole structure may also include an outsole covering at least a portion of the ground-facing surface of the midsole, and a height of the sole structure may be greatest at the midfoot region.

Ski boot sole (10), characterized in that it comprises: a plate (11) made of a composite material comprising reinforcing ribs (20); rear (30) and front (40) components extending under the plate (11) and forming gripping tread patterns (35, 45).

Extruded components for articles of footwear and methods of making such articles of footwear are disclosed. A carrier can be formed from a first material, the carrier including an attachment surface configured to attach to an upper and a receiving surface having a plurality of receptacles. A second material can be extruded into a plurality of the receptacles to form cushioning elements of a sole.

A sole structure for an article of footwear, the sole structure including a forefoot region and a heel region. The sole structure further includes a chassis plate, an outsole plate extending from the forefoot region to the heel region, the outsole plate including a recess disposed in a top surface, wherein the outsole plate is disposed below the chassis plate, and a cushioning element disposed within the recess.
