Footwear including sole assembly
First Claim
1. An article of footwear defining a forefoot region, a hindfoot region, and a midfoot region disposed between the forefoot region and the hindfoot region, the article of footwear comprising:
- an upper including a foot cavity;
a sole assembly oriented below the upper, the sole assembly comprising;
a non-stochastic support structure including;
a plurality of cells arranged in an ordered, repeating manner, wherein the plurality of cells are defined, at least in part, by a plurality of struts that interconnect to form a plurality of nodes disposed between and spaced apart from a top and a bottom of the non-stochastic support structure, the plurality of nodes including nodes that are each disposed at a junction of three or more struts from the plurality of struts, wherein a first strut of the three or more struts extends along a first plane and a second strut of the three or more struts extends along a second plane that is not coplanar with the first plane; and
a top plate that extends around a periphery of the non-stochastic support structure; and
a stochastic support structure including cells with random variations in location, shape, and size, wherein the stochastic support structure is manufactured separately from the non-stochastic support structure, and wherein the non-stochastic support structure defines a cavity operable to receive and support the stochastic support structure above the non-stochastic support structure.

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.

15. An article of footwear that defines a forefoot region, a hindfoot region, and a midfoot region disposed between the forefoot region and the hindfoot region, the article of footwear including a sole assembly comprising:
-
a lattice structure that is formed from a plurality of cells, wherein the lattice structure extends laterally across the sole assembly, from a medial side of the of the hindfoot region to a lateral side of the hindfoot region and from a medial side of the midfoot region to a lateral side of the midfoot region, and wherein the lattice structure includes a flange that extends inwards, from an edge of the lattice structure, over a portion of a top surface of the lattice structure; a heel support that mates with the flange and includes a frame configured to receive a heel of a wearer, wherein the heel support and the lattice structure collectively form a cavity; and a compression element that is disposed in the cavity and above the heel support, wherein the compression element extends from the hindfoot region of the article of footwear to the forefoot region of the article of footwear. - View Dependent Claims (16, 17)
