Abstract
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.
