A vamp is provided, for being arranged on a sole structure and defining a cavity with the sole structure, the vamp includes a first portion, a second portion, a third portion, a fourth portion and a fifth portion; the first portion is tubular and has an opening communicating with the cavity; the first, second, third, fourth and fifth portions are configured to respectively correspond to different parts of a foot, regarding deformabilities, the second portion is greater than the first portion, the first portion is greater than the fifth portion, the fifth portion is greater than the fourth portion, and the fourth portion is greater than the third portion. A shoe body is further provided, including the vamp and the sole structure, the vamp is arranged on the sole structure to define the cavity with the sole structure for receiving the foot.

The present disclosure is directed to articles that include a cured coating that includes a matrix of crosslinked polymers and optionally a colorant (e.g., pigment particles or dye or both). The cured coating can include a matrix of crosslinked polymers. The cured coating is a product of crosslinking a coating composition comprising uncrosslinked polymers (e.g., a dispersion of uncrosslinked polymers in a carrier to form the matrix of crosslinked polymers), wherein the uncrosslinked polymers are crosslinked to form the matrix of crosslinked polymers. The matrix of crosslinked polymers can be elastomeric. The present disclosure is also directed to articles including these bladders, methods of forming these bladders, and methods of making articles including these bladders, where the bladders include the cured coating.

A last system and a method of making the last system are disclosed. The last system includes a last member and an exterior layer. The exterior layer becomes deformable when heated above a characteristic temperature. The method can include forming a braided footwear component on the last system. The exterior layer may be joined with the braided footwear component by heating the last system above the characteristic temperature.

A textile component includes a yarn which includes a thermoplastic material. A blowing agent with at least activation condition is included into the textile, either by inclusion in the yarn or impregnating in the textile after forming an un-foamed textile. Upon triggering the activation condition of the blowing agent, the blowing agent introduces a plurality of cavities, i.e. cells, into the thermoplastic material. The textile then comprises a multicellular foam area of the textile wherein the multicellular foamed area comprises a multicellular foam surrounding a core yarn. The textile, in either its un-foamed or foamed condition, can be incorporated into a variety of articles, such as an article of footwear.

An article, such as an article of footwear includes, a textile component. The textile component includes a yarn. The yarn includes a thermoplastic material and a blowing agent with an activation condition. Upon triggering the activation condition of the blowing agent, the blowing agent introduces a plurality of cavities, i.e. cells, into the thermoplastic material, creating a multicellular foam area of the textile.

A knitted component may include a first area, where the first area includes a plurality of knit loops comprising a first yarn. The knitted component may also include a second yarn at least partially inlaid within the first area of the knitted component such that the second yarn extends between at least a first loop and a second loop of the plurality of knit loops. The second yarn may have a foamable material comprising a blowing agent and a thermoplastic polymer.

A fiber bound engineered material is provided that imparts an intended characteristic at an intended relative location. A fiber layer is entangled with additional fibers in a manner to create a non-uniform engineered material. The lack of uniformity of a fiber bound engineered material may be accomplished through manipulation of the fibers and/or through fiber binding a scrim. The fiber layer binds with additional fibers through entanglement such that a mechanical connection between the entangled fibers is provided. This entanglement allows the fibers to bind without supplemental adhesives, interlacing, or connections. Variations in the fibers and/or inclusion of scrim materials prior to entanglement allows for an intended characteristic (e.g., a functional characteristic) at an intended relative location (e.g., a position determined by an article to be formed therefrom).

A last for forming an upper of an article of footwear includes an exterior surface, where the exterior surface includes a plurality of three dimensional structural surface components disposed over at least 50% of the exterior surface of the last.

An article of footwear is provided that includes a sole structure and an upper attached to the sole structure. The upper includes an exterior layer and a base layer, and the exterior layer includes a biodegradable layer and a biologically active agent capable of biodegrading the biodegradable layer.

A method of manufacturing a non-woven fabric includes the steps of: (a.) providing a substrate, wherein the substrate is air permeable in at least a portion of its surface; (b.) providing a fiber transfer device adapted to transfer fibers onto the substrate; (c.) transferring a first plurality of fibers onto the substrate; and (d.) applying a pressure differential to the air permeable portion of the substrate, wherein the strength of the pressure differential is varied across the surface of the substrate.
