A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.

A component for a sole structure of an article of footwear that includes an upper and an insole includes an extrusion that comprises a substrate material and a deposition. The extrusion extends along a path that defines an extrusion array. The deposition includes a first helical portion defined by a first helix angle and a first helix axis.

A knitted article having a first layer and a second layer is described. The first layer is formed from a first yarn having a first shrinkage rate and the second layer is formed by a second yarn having a second shrinkage rate. The shrinkage rate of the first yarn is greater than the shrinkage rate of the second yarn when subjected to heat. Upon heat exposure, the second layer forms a raised structure. The raised structures have a length that is generally perpendicular to the lateral-to-medial course-wise direction of the knitted article.

A method of making a midsole includes selecting a plurality of yarns. At least two yarns of the plurality of yarns have different properties relative to one another. The method further includes bundling the plurality of yarns to form a bundled yarn structure and intertwining the bundled yarn structure to form a twisted yarn structure. Further, the method includes depositing the twisted yarn structure into a first mold within an autoclave and applying a supercritical fluid to the twisted yarn structure. The method further includes supercritical fluid infiltrating and saturating the twisted yarn structure, depressurizing the autoclave to cause a foaming process therein to convert the twisted yarn structure into an anisotropic foam blank, and depositing the anisotropic foam blank within a second mold that is configured as a midsole for an article of footwear.
