A cushioning member includes a first lattice structure and a second lattice structure. The first lattice structure includes a first network of struts and nodes with voids defined between the struts and nodes. The second lattice structure includes a second network of struts and nodes with voids defined between the struts and nodes. The first network of struts and nodes is interwoven with the second network of struts and nodes such that the first network of struts and nodes extends through the voids in the second network of struts and nodes.

The present invention concerns a shoe upper comprising a woven portion, wherein the woven portion comprises a plurality of warp yarns; a plurality of weft yarns; at least one stitching yarn, wherein the stitching yarn is integrally woven into the fabric during the weaving process by laterally displacing the stitching yarn substantially along the weft direction and moving the stitching yarn in and out of at least one open reed gap in a reed.

The present disclosure is related to three-dimensionally printed articles for use in footwear and associated systems and methods. In some embodiments, a three-dimensionally printed article may comprise a closed-cell foam. The closed-cell foam may have a gradient in and/or may be a single integrated material. In some embodiments, a three-dimensionally printed article may comprise a sensor. The use of such arrangements can, according to certain embodiments, allow for the production of improved articles of footwear and/or customized articles of footwear.

A method of manufacturing a foam component includes printing a preform with a three-dimensional printer. The preform is formed from a pre-saturated mixture of a base material that is at least partially saturated with a foaming agent. The preform is foamed by heating the preform to be at or above a glass transition temperature of the base material, thereby causing the foaming agent to nucleate and expand to form the foam component. Foaming occurs at atmospheric pressure. The preform includes a preliminary lattice structure that corresponds with a final lattice structure of the foam component.

An article of footwear includes a midsole comprising a lattice structure including an upper side and a lower side. The lattice structure is comprised of a network of interconnected laths, the laths configured as parallel wave structures in multiple layers, wherein the wave structures in a first layer are transverse to the wave structures in a second layer. An upper is disposed above the midsole and an outsole is disposed below the midsole.

A system and method of manufacturing an article of footwear about a footwear last that is shaped to approximate a human foot for the type of footwear being manufactured. Layers of material may be deposited on or in proximity to first and second zones of the footwear last, which may be rotated relative to a nozzle that deposits the material. For instance, the material may be deposited on a substrate provided on the footwear last.
