Abstract
An article of footwear has an upper and a sole structure. The upper includes a base layer and one or more tensile strands. The sole structure includes an auxetic element operable to expand in two orthogonal horizontal directions in response to a tension applied in one of the directions. Each tensile strand has at least one end secured in fixed position relative to a peripheral region of the sole structure.
Claims14
An article of footwear comprising:
- an upper adapted to receive a foot of a wearer;
- a sole structure comprising:
- an upper surface and an opposing ground-contacting surface, the upper surface directly secured to the upper;
- a plurality of apertures extending from at least one of the upper surface or the ground-contacting surface, and a plurality of sole portions disposed between adjacent ones of the plurality of apertures;
- a lateral sidewall and a medial sidewall each extending upward in contact with the upper and such that the upper is partially disposed between the lateral sidewall and the medial sidewall;
- the upper comprising:
- a base layer and a plurality of tensile strands, each tensile strand having a first end and a second end, a portion of each tensile strand between the first end and the second end being separate from the material of the base layer and lying adjacent to a surface of the base layer;
- and
- wherein the first end of each tensile strand is affixed to the sole structure;
- and
- wherein a tension applied through each of the plurality of tensile strands induces a deformation of the sole structure such that the lateral sidewall and the medial sidewall are drawn toward each other, and such that at least a portion of the plurality of apertures experience a dimensional expansion.
