An outsole includes a substantially flat reference surface formed on a lower side of the outsole, and studs projecting downward from the reference surface and each having a projection surface positioned below the reference surface. Midsole hollows are provided in a lower portion of a midsole. The midsole hollows are each defined between an upper portion of the outsole and an associated one of midsole recesses formed in a lower surface of a lower midsole at positions facing upper sides of the studs.

An article of footwear including a sole component including a baseplate having a bottom surface and at least a first ground engaging member extending substantially downward from the bottom surface of the baseplate, and a first elongate support member extending substantially downward from the bottom surface of the baseplate, abutting the first ground engaging member at a side portion, and extending horizontally from the side portion of the first ground engaging member. The ground engaging member may include a lower portion and an upper portion, the upper portion extending downward from the bottom surface of the baseplate, the lower portion being made of a different material than the upper portion. The distance that the elongate support member extends downward from the bottom surface of the baseplate is less than the distance that the ground engaging member extends downward from the bottom surface of the baseplate.

The present disclosure is directed to an article of footwear including an upper configured to receive a foot and a sole component fixedly attached to a bottom portion of the upper. The sole component may include a baseplate having a bottom surface and at least a first ground engaging member extending substantially downward from the bottom surface of the baseplate and a first elongate support member extending substantially downward from the bottom surface of the baseplate, abutting the first ground engaging member at a side portion, and extending horizontally from the side portion of the first ground engaging member. The first support member may extend horizontally away from the first ground engaging member in a direction toward a region of the sole component adjacent to a gap in the sole component.

A sole assembly may be formed by a method that includes positioning a plurality of preforms having different colors together to form a sole assembly preform and placing the sole assembly preform in a recess in a first portion of a mold assembly. The sole assembly preform is subjected to heat for a predetermined amount of time such that the plurality of preforms bond to one another to form a sole assembly.

An article comprises a cushioning assembly that comprises a first bladder element forming a first fluid chamber. The cushioning assembly further comprises a second bladder element within the first bladder element. The second bladder element forms a second fluid chamber sealed from and within the first fluid chamber. At least one reinforcement element is operatively connected to and in contact with at least one of the first bladder element and the second bladder element. The at least one reinforcement element is configured to reinforce the cushioning assembly under a load applied to the first bladder element. A method of manufacturing an article with the cushioning assembly is provided.

A sole structure for an article of footwear includes a first plate having a first surface. The first plate includes a forefoot region at an anterior end, a heel region at a posterior end, and a mid-foot region. The sole structure further includes a second plate having a second surface opposing the first surface of the first plate. The second plate has a first end attached to the forefoot region of the first plate and a second end that is spaced apart from the first surface of the first plate. A cushion is disposed between the first plate and the second plate and has a first side attached to the first surface of the first plate and a second side attached to the second surface of second plate. The cushion extends continuously from a medial side of the sole structure to a lateral side of the sole structure.

Systems and methods are disclosed including a tri-layer orthotic system having a heel portion and a forefoot portion to support respective heel and forefoot portions of a foot through at least a portion of a gait cycle. The tri-layer orthotic system can include an upper layer suspended over a mid-layer and a base layer to create a rear spring section, a mid-spring section, and a front spring section. A distal toe portion of the mid-layer can form the forefoot portion of the tri-layer orthotic system and a heel upper layer portion of the upper layer can form the heel portion of tri-layer orthotic system.

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.

Sole structures, foot support systems, articles of footwear, and/or other foot-receiving devices include: (a) a first footwear component having a ground-facing surface, wherein a forefoot portion of the ground-facing surface includes arched medial and lateral surfaces and (b) a second footwear component having an upper-facing surface, wherein a forefoot portion of the upper-facing surface includes arched medial and lateral surfaces that face (and optionally contact) the respective arched medial and lateral surfaces of the first footwear component. The first and second footwear components are movably engaged together such that: (a) the arched medial surface of the first footwear component moves with respect to and along the arched medial surface of the second footwear component and (b) the arched lateral surface of the first footwear component moves with respect to and along the arched lateral surface of the second footwear component.

A shoe sole (1) comprising an outsole (3), an insole (2) and a midsole (5) which extends between the insole (2) and the outsole (3), the midsole (5) being composed of a plurality of bars (6) which are substantially transversal and are aligned substantially longitudinally over the length of the sole, the insole (2) and the bars are composed of an elastomeric material.
