An injection molded integral multicolor thermoplastic elastomeric foamed sole, comprising an integral sole made from thermoplastic elastomeric foaming bodies of at least two colors, and on surfaces thereof are provided grains of arbitrarily superposed injection strips; the foamed sole is made by: mixing, milling and heating thermoplastic elastomer raw materials of at least two colors, lubricants, and foaming auxiliaries to be thermoplastic elastomeric fused-masses, adding respectively gas-foaming agents at 0.2%-10% of thermoplastic elastomeric raw materials, compressive injecting gas-foaming agents respectively into thermoplastic elastomeric fused-masses, fully mixing to form thermoplastic elastomeric gas foamed polymers, and extruding foaming strips of thermoplastic elastomeric gas polymers of the at least two colors with an extrusion and injection process and/or co-extruding the foaming strips of thermoplastic elastomeric gas polymers of the at least two colors by a co-extrusion process into molds to form arbitrarily superposed strips, clamp molds, discharge gas and form.

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.

Beads may be stitched to a substrate layer and then fused to form structures including foam midsoles, foam pads, and other foam structures. Beads may be embroidered to multiple substrate layers and then folded or stacked together to form a preform used in a mold to form a midsole.

A sole for an article of footwear includes a continuous dispensed component forming a first layer and a second layer. The first layer is disposed directly on top of the second layer. The continuous dispensed component forms a medial sidewall and a lateral sidewall. The first layer includes a starting point where the continuous dispensed component is first dispensed. The continuous dispensed component continuously transitions from the first layer to the second layer at the starting point.

Footwear or other foot-receiving devices include various conforming fit, stability, and/or “locked down” feel features. The uppers (or foot-covering components) for such articles of footwear (or other foot-receiving devices) may include one or more of: (a) an upper shell defining an interior chamber, wherein the upper shell includes a plantar support surface and sidewalls extending from an outer perimeter of the plantar support surface; (b) a bootie component (e.g., formed as a sock or sock-like garment) received in the interior chamber; (c) one or more foot wrapping bands; and/or (d) an interior midsole within the bootie component. The bootie component and/or the foot wrapping band(s) may be secured to the upper shell at a location inside an outer perimeter of the plantar support surface of the upper shell and beyond the bight line between the sidewalls of the upper and the plantar support surface.

The disclosed embodiments relate to portions of an article of footwear formed from an extruded member. In certain embodiments, a sole or portion of a sole can be formed from one or more extruded members. In certain embodiments, the extruded member can be a single, continuous piece of solid material. In certain embodiments, a sole for an article of footwear can be fashioned from an extruded member formed in a controlled geometric pattern. In certain embodiments, the sole can include one or more layers.

A sole structure for an article of footwear comprises a midsole system with a plurality of cushioning units, each having multiple cushioning layers configured to work together as a system to absorb a compressive load, such as a dynamic compressive load due to impact with the ground, in stages of progressive cushioning according to the relative stiffness values of the layers. Various midsole systems disclosed include isolated cushioning units, linked cushioning units, sole layers having stanchions interfacing with the midsole system, midsole systems with sole layers having keyed and unkeyed portions overlying a bladder, and midsole systems with vertically-stacked cushioning units disposed in inverted relationship to one another.

A sole structure for an article of footwear comprises a midsole having four stacked polymeric sheets bonded to one another to define a first cushioning layer, a second cushioning layer, and a third cushioning layer. Each cushioning layer comprises a sealed chamber retaining gas in isolation from each other sealed chamber. Bonds between adjacent ones of the sheets are arranged such that the third cushioning layer is stacked directly above the first cushioning layer with the second cushioning layer bordering both the first cushioning layer and the third cushioning layer, and the sealed chamber of the second cushioning layer includes a plurality of elongated segments each extending lengthwise across a longitudinal midline of the midsole at a respective acute angle to the longitudinal midline.

The present disclosure is directed to articles that include one or more coated fiber(s) (i.e., fiber(s) with a cured coating disposed thereon), where the coating includes a matrix of crosslinked polymers and optionally a colorant (e.g., pigment particles or dye or both). The cured coating is a product of crosslinking a coating composition including uncrosslinked polymers (e.g., a dispersion of uncrosslinked polymers in a carrier, wherein the uncrosslinked polymers are crosslinked to form the matrix of crosslinked polymers). The present disclosure is also directed to articles including the coated fibers, methods of forming the coated fibers and articles, and methods of making articles including the coated fibers.
