An article of footwear includes a fitting system with an upper member that is supported by the upper and a strand guide that is supported by the sole structure. The strand guide is flexible and flexes in concert with the sole structure. The strand guide has a guide surface. The fitting system further includes a tensioning system with a flexible strand that is configured to bias the upper member toward the strand guide. The flexible strand has a first section coupled to the upper member and a second section extending through the sole structure. The second section abuts the guide surface. The second section is configured to slide across the guide surface as a result of flexure of the strand guide. The first section and the upper member are configured to move relative to the sole structure as a result of sliding of the second section across the guide surface.

A cushioning article includes a bladder enclosing an interior cavity and retaining a gas in the interior cavity. A tensile component is disposed in the interior cavity and includes tensile layers and a plurality of tethers connecting the tensile layers. The tensile layers are connected to an inner surface of the bladder such that the tethers span across the interior cavity. The bladder has an inwardly-protruding bond that joins an inner surface of the bladder to the tensile component, protrudes inward into the interior cavity, and partially traverses the plurality of tethers such that the bladder is narrowed at the inwardly protruding bond and the gas in the interior cavity fluidly communicates across the inwardly-protruding bond. A method of manufacturing a cushioning article is disclosed.

A sole assembly for an article of footwear includes a midsole that is formed from at least a bladder and foam midsole component. The midsole has a ground facing surface and a sidewall, and the bladder meets the foam midsole at a component boundary on the sidewall. An etching extends into both the foam midsole and the bladder. The etched channel has a depth into the sidewall of between about 2 μm and about 1000 μm and continuously extends across the component boundary.

A sole structure for an article of footwear includes an outsole defining a ground-contacting surface, a midsole disposed between the outsole and the upper, and a plate attached to the midsole and defining a recess extending in a direction away from the outsole and toward the upper, the recess including a first retainer. The sole structure further includes a first cushion having a first portion received within the recess, the first portion engaging the first retainer to maintain a desired position of the first cushion relative to the plate.

The present invention provides a method for making a sole structure with a knitted fabric and a sole structure. The method comprises steps of: placing a thermoplastic filling material in a knitted fabric, sealing an opening of the knitted fabric, placing the knitted fabric with the opening sealed in a mold, applying a heating temperature to melt the thermoplastic filling material of the knitted fabric, and restricting a shape of the knitted fabric via the mold to make a sole structure. The sole structure includes a compressible elastomer and a knitting texture wrapped around the compressible elastomer and fused with a surface of the compressible elastomer. The compressible elastomer is formed from the thermoplastic filling material after being melted and cooled. The knitting texture is formed from the knitted fabric and is capable of being directly observed from an appearance of the sole structure.

A fluid-filled chamber includes first subchamber having a substantially U-shape. The fluid-filled chamber also includes a second subchamber having a substantially U-shape and being spaced apart from the first subchamber in a direction extending along a longitudinal axis of the fluid-filled chamber.

A system and method directed for a footwear insert whereby the insert provides a more efficient and durable method for providing cushioning in footwear and utilizes a cushioning method that uses deflection as a way to provide cushioning similar to a trampoline that is durable, retains its shape over time, and has very little energy loss.

An article of footwear includes an upper and a sole structure with a sole member. The sole member can include a set of apertures that is formed along various surfaces of the sole member. The sole member can be manufactured using a customized cushioning sole system, forming generally circular patterns throughout the sole member. A user's foot morphology and/or preferences may be used to design the sole member.

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.

One or more aspects of the present disclosure provide articles of manufacture and components of articles that incorporate an optical element that imparts a structural color to the component or the article. The component comprises a thermoplastic polymeric material, and can include or be made to have a textured surface.
