A sole structure for an article of footwear includes a bladder and at least one foam insert. The bladder includes an upper surface having a first portion defining a chamber and a second portion defining at least one recess adjacent to the chamber. The at least one foam insert is disposed within the at least one recess and has a top surface that is substantially flush with the first portion of the upper surface of the bladder. The first portion of the upper surface is exposed to the at least one foam insert.

A shoe comprising an upper and a sole assembly connected to the upper, the sole assembly comprising a midsole and an outsole comprising a forefoot region, a midfoot region, and a rearfoot region. The outsole comprises a first traction zone located in the forefoot region or the midfoot region of the outsole and a second traction zone located in the midfoot region or the rearfoot region of the outsole, wherein the first traction zone and/or the second traction zone have a wave-like configuration.

Described are soles for a shoe, in particular for a sports shoe, with a midsole. The midsole includes a first sole region, which includes particle foam. The midsole further includes a deformation region within the midsole, wherein the deformation region has a volume greater than that of a single expanded particle and is positioned so that it allows a sideward deformation of the material of the first sole region under a pressure load on the sole.

An inner sole structure for being mounted inside footwear for engagement by the foot comprises a middle sole part covered by a top part. The middle sole part defines has a thickness providing for supporting the foot and defines a longitudinal channel devoid of any material therein and defining an opening covered by the top sole part. When the inner sole structure is inside the footwear and engaged by the foot, the longitudinal channel is positioned under the foot of the wearer and is aligned with a longitudinal portion of the foot corresponding to a plantar fascia position of the foot to avoid tension against this foot portion. The inner sole structure comprises a support element for being mounted to an inner sole part of the footwear to be engaged by the foot. The support member is positioned to be engaged by a region of the foot corresponding to a position extending between at least near a fifth metatarsal rear end position of the foot to a heel bone position of the foot for providing stability to the foot for controlled supination.

A support structure for a shoe sole includes a support piece with elasticity, the support piece is provided at the forefoot or/and arch position of the shoe sole and is laid out along the width direction of the shoe sole, the support piece is provided with a number of raised arc sections or/and concave arc sections along the width direction of the shoe sole. Shoe soles and athletic shoes include the support structure described above, the shoe sole support structure bonded or integrally molded to the upper surface of the shoe midsole, or bonded or integrally molded between the shoe midsole and the shoe outsole, or embedded inside the shoe midsole.

Articles of footwear, systems, and methods include an upper portion, a lower portion, secured to the upper portion, the lower portion including an out-sole and an airbag assembly. The airbag assembly includes a first sheet and a second sheet forming a seal therebetween around a perimeter of the first and second sheets. The airbag assembly further includes an electronic assembly, comprising a circuit board and electrical conductors disposed on the circuit board, wherein an internal portion of the electronic assembly is disposed between the first and second sheets and within the seal formed therebetween and an external portion of the electronic assembly is disposed outside of the seal.

A golf shoe with a sole assembly having a sidewall reinforcement structure is provided. The reinforcement structure may be formed from a carbon composite or other reinforcing material. The reinforcement structure is molded into the sole assembly for reinforcing softer midsole sidewalls, and for providing increased stability and maintaining forefoot flexibility. The structure is generally U-shaped with a medial and lateral side wing and a bridge connecting the wings. The medial wing may be angled rearward to support the rearfoot, and the lateral wing may be angled forward to support the midfoot. Thus, the reinforcement structure may hold and support the medial and lateral sides of the golfer's foot as they shift their weight while making a golf shot. At the same time, the shoe has good flexibility so the golfer is able to walk and play the course and engage in other golf activities comfortably.

A sole for an article of footwear includes a cored midsole defining a top surface, a bottom surface, and a perimeter surface extending from the top surface to the bottom surface. The cored midsole defines apertures extending diagonally from the top surface of the cored midsole to the bottom surface of the cored midsole.

A sole structure for an article of footwear, the sole structure defining a footbed and a ground-engaging surface and including a chassis extending from an anterior end of the sole structure to a posterior end of the sole structure, and a bladder supported within the chassis and extending from a first end in a forefoot region of the sole structure to a second end exposed at the posterior end of the sole structure, the bladder including a first curved portion in the forefoot region and a substantially flat portion at the posterior end of the sole structure.

A method of manufacturing an article of footwear includes perforating a midsole body of a sole structure to form perforations through the midsole body, wherein the midsole body has perforated holes established by the perforations. The method includes disposing each of a plurality of proprioceptive elements of the sole structure in a different one of the perforated holes as an integral portion of the midsole body surrounded by the perforations. Each central axis of the plurality of proprioceptive elements disposed in a medial sidewall portion of the midsole body and a lateral sidewall portion of the midsole body is angled relative to a vertical axis of the midsole body and is configured to align with a direction of a lateral loading force on the midsole body at a location of the respective proprioceptive element.
