The auxetic layer includes an auxetic structure defining a repeating pattern of shapes, with each of the shapes defined by perimeter walls and an interior recess. The auxetic layer includes a first region and a second region. Each interior recess in the first region provides a void exposing the base layer, and each interior recess in the second region is at least partially filled with a recess material.

Abstract: 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.

Abstract: A method of making a shoe includes printing a midsole having a platform and a lattice structure. The platform and lattice structure are integrally formed by printing a first surface of the platform to conform to a sole of a foot of a user and, in association therewith, printing the lattice structure on a second surface of the platform opposite the first surface of the platform. The method also includes positioning the midsole substantially within an outsole such that the lattice structure is substantially facing the outsole and the platform is substantially facing an upper.

Abstract: The present invention is directed toward cushioning for a sole structure for an article of footwear. The cushioning is three-dimensionally (3D) printed cushioning formed from a plurality of cells. Each cell in the plurality of cells includes a lattice of elongate structures that extend symmetrically around an offset axis. The elongate structures of adjacent cells in the plurality of cells connect so that the plurality of cells form a unitary structure and, as the elongate structures of each cell are compressed by a compressive force, the elongate structures of each cell create a lateral shear.

Abstract: An article of footwear includes an upper and a sole assembly. The sole assembly includes a unitary, open-celled structure. Specifically, the sole assembly includes a lattice structure having an interconnected network of struts and nodes that cooperate to define voids. The struts and nodes are configured to generate predetermined support and flexure properties within the network. The lattice may be configured as a conformal lattice, being contoured to receive accessories or complementary support structures. The sole assembly may further include an insert formed of compression material (e.g., foam). In operation, the lattice and foam insert cooperate to provide stability and cushioning to the article of footwear.

Abstract: An article of footwear includes a midsole, an upper disposed above the midsole, and an outsole disposed below the midsole. The midsole includes a lattice structure having an upper side and a lower side, wherein the upper side is a user-facing side and the lower side is a ground-facing side. A first platform is integrally formed into the upper side of the lattice structure. A second platform is integrally formed into the lower side of the lattice structure. The lattice structure extends from the first platform to the second platform.

Abstract: A vent structure and a method of forming a vent from a vent structure are described herein. The vent structure includes a first elongate member, a second elongate member, and a set of ribs extending between the first elongate member and the second elongate member. The first elongate member is configured to be attached to a first side of an opening formed in an article of apparel and the second elongate member is configured to be attached to a second side of the opening, the second side being opposite the first side. Collectively, the first elongate member, second elongate member, and the set of ribs bias the first side and the second side to an open configuration that exposes and expands the opening.
