Abstract
An article of footwear includes a sole structure and an upper that is attached to the sole structure. The upper defines a cavity that is configured to receive a foot of a wearer. The upper is at least partially defined by a textile. The textile includes a first area that is substantially smooth. The first area defines a reference boundary that conforms to the cavity. The textile includes a second area. The second area includes a plurality of projection structures that project away from the reference boundary and outwardly from the cavity at varying heights. The second area includes a plurality of recess structures that recess away from the reference boundary and inwardly toward the cavity. The plurality of projection structures and the plurality of recess structures are in an alternating arrangement across the textile.
