A sole structure for an article of footwear includes a unitary cushioning component comprising a plurality of scrap foam pieces configured as a plurality of different polyhedron shapes and a resin binder securing the scrap foam pieces to one another. The sole structure may comprise a midsole including an outer shell defining a central cavity. The cushioning component may be disposed in the central cavity as a core of the midsole. A method of manufacturing an article of footwear cutting the scrap foam body into pieces, mixing the pieces with a resin binder, and compression molding the mixed pieces and resin binder in a mold to form a cushioning component of a sole structure of the article of footwear.

A sole structure for an article of footwear comprises a midsole body having a proximal surface and a distal surface. Proprioceptive elements may extend in the hole in the midsole body, and translate toward the proximal surface in the holes upon a force directed along a central axis of the hole at a distal end of the proprioceptive elements. In various embodiments, the holes may angle relative to vertical from the proximal surface to the distal surface, the holes may be defined by perforations and the proprioceptive elements may be integral portions of the midsole body, or the midsole body may have a plurality of annular holes at the proximal surface, and a plurality of annular recesses in the distal surface, and a plurality of proprioceptive elements, each centered in a different annular hole of the plurality of annular holes. Methods of manufacturing articles of footwear are described.

A shoe insole apparatus capable of buffering and massaging includes a pad part laid on a bottom surface inside a shoe and a buffering part which adheres to a portion including a central portion to a heel portion of the pad part and absorbs shock applied to a heel of a wearer, wherein the buffering part includes a body part of which a height decreases from the heel portion of the pad part toward a ball portion, a buffering groove which is positioned in an upper portion of the heel portion of the pad part, passes through the body part, and is formed in a quadrangular shape, and a plurality of buffering plates which are formed to extend to connect two inner surfaces facing each other among inner surfaces of the buffering groove and are in contact with the heel of the wearer.

A footwear construction includes a sole assembly having a convoluted lower surface with multiple rolling peaks and valleys, and first and second midsoles having different durometers to provide dynamic stability, cushion and/or traction. The second midsole can include apertures that extend into some peaks so those peaks are compressible and conform well to underfoot terrain. The sole assembly can include certain lateral or medial peaks that transition to a perimeter of the sole assembly, and that are of a truncated shape with a sidewall to provide firmness and/or rigidity to the sole assembly around the perimeter. Other peaks can be disposed inward from the lateral or medial peaks and can be of a lesser firmness so those central peaks can provide cushioning and/or macro traction capabilities. A related method of manufacture also is provided.

A plate is used for a sole that forms a part of a shoe. The plate includes a reinforcement portion composed of a composite material containing a synthetic resin and a plurality of fibers. The plurality of fibers in the reinforcement portion each have a weight average fiber length not shorter than 0.4 mm and not longer than 7.0 mm and have such an orientation property that orientations thereof are aligned in a foot length direction.

An article of footwear includes a sole structure coupled with an upper that defines a forefoot region, a midfoot region, and a heel region. The sole structure includes a plurality of pods that each have a pod body formed from a foam material that optionally has a coating disposed on an outer surface of the pod body. The sole structure includes a chassis attached to a bottom surface of each of the plurality of pods. The chassis includes a plurality of ground contacting regions and an elongated fork structure. The elongated fork structure includes a chassis stem, a first chassis leg, and a second chassis leg that each extend from the chassis stem through the heel region, the midfoot region, and the forefoot region of the sole structure. A continuous elongated groove is positioned between and extends along substantially the entire length of the first and second chassis leg.

An article of footwear comprising a sole and an upper on the sole. The sole comprises a dandelion latex foam material. The dandelion latex foam material comprises dandelion latex and at least one other natural or synthetic polymer. The dandelion latex foam material is between 20% and 80% dandelion latex.

A sole includes: a midsole main body; an elastic portion; and a pressing member. The midsole main body includes a containing portion. The elastic portion is contained in the containing portion in a compressed state. The pressing member has an elastic modulus higher than an elastic modulus of the elastic portion in the compressed state, and presses the elastic portion so that the elastic portion is maintained in the compressed state. The elastic modulus of the elastic portion in the compressed state is larger than an elastic modulus of the midsole main body.

A cushioning member for an article of footwear is provided and includes a first barrier member defining a first compartment and a second compartment and being formed from a first material. A second barrier member is attached to the first barrier member, covers the first compartment to define a first interior void, and covers the second compartment to define a second interior void. The second barrier is formed from a second material different than the first material. The cushioning member also includes a first quantity of particulate matter disposed within the first interior void and a second quantity of particulate matter disposed within the second interior void.

A sole structure for an article of footwear includes a forefoot region disposed adjacent an anterior end, a heel region disposed adjacent a posterior end, and a mid-foot region disposed intermediate the forefoot region and the heel region. The sole structure further includes fluid-filled bladder having a first segment extending along a medial side in the heel region, a second segment extending along a lateral side in the heel region, and a web area disposed between the first segment and the second segment. Additionally, the sole structure includes an outer sole member having an upper portion extending from a first end in the forefoot region to a second end in the heel region. The second end of the outer sole member is received on a first side of the web area. The outer sole member also includes a rib extending downwardly from the upper portion and defining a cavity.
