Layered sole structure for an article of footwear

A sole structure can include provisions for improving the cushioning characteristics and stability of an article of footwear. The sole structure may include multiple layers with specialized structural properties designed to integrate regions of stiffness with cushioning layers. In some cases, the sole structure can include at least two independent stability layers that differ in stiffness.

SOLE STRUCTURE FOR ARTICLE OF FOOTWEAR

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.

A material is disclosed herein that may include a plurality of chambers. A wall, a bottom surface, and a top surface may define a chamber. The wall may have a top portion and a bottom portion where the top portion may be adjacent to the top surface, and the bottom portion may be adjacent to the bottom surface. The wall may include an elastic material, and an aerogel powder or an aerogel foam may be disposed within the chamber. This material can be incorporated into clothing and shoes, for example.

FOOTWEAR WITH FLUID-FILLED BLADDER
20210368920 · 2021-12-02 · ·

An article of footwear has a sole structure that includes a bladder having stacked polymeric sheet secured to one another at a peripheral bond and defining a first sealed chamber between the first and second polymeric sheets, a second sealed chamber between the second and third polymeric sheets, and a third sealed chamber between the third and fourth polymeric sheets, each of the first, second, and third sealed chambers retaining fluid in isolation from one another. Different patterns of bonds secure adjacent ones of the polymeric sheets to one another, resulting in different geometries of the sealed chambers. The sealed chambers are configured (e.g., by pressure, shape, position, and/or size) to elastically deform to provide a desirable cushioning experience.

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.

SOLE HAVING CARBON FIBER AND METHOD OF MANUFACTURING THE SAME
20220175085 · 2022-06-09 · ·

A sole includes a bottom layer and a carbon fiber layer. The bottom layer has at least two engaging portions. The carbon fiber layer is penetrated by at least two fitting holes. The at least two engaging portions are engaged with the at least two fitting holes, respectively. The diameter of the at least two fitting holes, which is close to the bottom layer, is less than the diameter of the at least two fitting holes closed to a upside surface of the carbon fiber layer. The at least two engaging portions undergo an injection process so as to be coupled to the at least two fitting holes, respectively, thereby reducing greatly the chance of injury which might otherwise happen to users as a result of separation of the bottom layer and the carbon fiber layer of the sole while the users are running quickly.

INJURY-PREVENTING COMPRESSION SHOE
20220175084 · 2022-06-09 ·

An injury-preventing compression shoe is disclosed. The injury-preventing compression shoe includes an upper sock portion attached to a lower sole portion. The upper sock portion includes a compressible, breathable sock-shaped sleeve. The shoe also includes a heel backing support, a carbon fiber midsole orthotic piece, and a foam edging attached around the sole portion to prevent foot deviation over the edges of the sole portion. The injury-preventing compression shoe is useful for reducing sports related injuries while improving performance.
