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.

Claims

1. An upper for an article of footwear having a sole structure, the upper comprising:

a smooth area disposed at a throat of the upper; and

a textured area disposed adjacent to the smooth area and including a first row of alternating projections and recesses that extends across the upper in a first direction substantially parallel to a longitudinal axis of the upper and between the throat of the upper and a distal end of the upper, each projection extending away from a foot-receiving cavity of the upper to a respective apex and defining a respective height between a co-extensive reference boundary of the smooth area and the respective apex, and each recess extending toward the cavity to a respective nadir and defining a respective depth between the co-extensive reference boundary of the smooth area and the respective nadir.

2. The upper of claim 1, wherein the height of at least one projection in the first row is different than the heights of the remaining projections in the first row.

3. The upper of claim 1, wherein the heights of the projections in the first row gradually increase as the projections extend further away from the throat of the upper and toward the distal end of the upper.

4. The upper of claim 1, wherein the depth of at least one recess in the first row is different than the depths of the remaining recesses in the first row.

5. The upper of claim 1, wherein the depths of the recesses in the first row gradually increase as the recesses extend further away from the throat of the upper and toward the distal end of the upper.

6. The upper of claim 1, wherein the textured area further includes a second row of alternating projections and recesses extending across the upper in a second direction substantially perpendicular to the first direction and between the throat of the upper and the sole structure at one of a medial side of the upper and a lateral side of the upper, each projection of the second row of alternating projections and recesses extending away from the cavity to a respective apex and defining a respective height between the co-extensive reference boundary and the respective apex, and each recess of the second row of alternating projections and recesses extending toward the cavity to a respective nadir and defining a respective depth between the co-extensive reference boundary and the respective nadir.

7. The upper of claim 6, wherein the projections in the second row of projections comprise a first projection and a second projection disposed closer to the sole structure than the first projection, the second projection defining a greater height than the first projection.

8. The upper of claim 7, wherein the textured area further includes a third row of alternating projections and recesses extending across the upper in a third direction substantially perpendicular to the first direction and between the throat of the upper and the sole structure at the other of the medial side of the upper and the lateral side of the upper, each projection of the third row of alternating projections and recesses extending away from the cavity to a respective apex and defining a respective height between the co-extensive reference boundary and the respective apex, and each recess of the third row of alternating projections and recesses extending toward the cavity to a respective nadir and defining a respective depth between the co-extensive reference boundary and the respective nadir.

9. The upper of claim 8, wherein the projections in the third row of projections comprise a third projection and a fourth projection disposed closer to the sole structure than the third projection, the fourth projection defining a greater height than the third projection.

10. The upper of claim 1, wherein the upper is formed from a knitted component including a knit element and a tensile element, the tensile element attached to the knit element within the smooth area of the upper and detached from the knit element within the textured area of the upper.

11. An upper for an article of footwear having a sole structure attached to the upper, the upper comprising:

a smooth area disposed at a throat of the upper; and

a textured area disposed adjacent to the smooth area and including a first row of alternating projections and recesses that extends across the upper in a first direction substantially perpendicular to a longitudinal axis of the upper and between the throat of the upper and the sole structure at one of a medial side of the upper and a lateral side of the upper, each projection extending away from a foot-receiving cavity of the upper to a respective apex and defining a respective height between a co-extensive reference boundary of the smooth area and the respective apex, and each recess extending toward the cavity to a respective nadir and defining a respective depth between the co-extensive reference boundary of the smooth area and the respective nadir,

wherein the upper further includes a second row of alternating projections and recesses that extends across the upper in a second direction substantially parallel to the longitudinal axis of the upper and between the throat of the upper and a distal end of the upper, each projection of the second row of alternating projections and recesses extending away from the cavity to a respective apex and defining a respective height between a co-extensive reference boundary of the smooth area and the respective apex, and each recess of the second row of alternating projections and recesses extending toward the cavity to a respective nadir and defining a respective depth between the co-extensive reference boundary of the smooth area and the respective nadir.

12. The upper of claim 11, wherein the height of at least one projection in the first row is different than the heights of the remaining projections in the first row.

13. The upper of claim 11, wherein the heights of the projections in the first row gradually increase as the projections extend further away from the throat of the upper and toward the sole structure.

14. The upper of claim 11, wherein the depth of at least one recess in the first row is different than the depths of the remaining recesses in the first row.

15. The upper of claim 11, wherein the depths of the recesses in the first row gradually increase as the recesses extend further away from the throat of the upper and toward the sole structure.

16. The upper of claim 11, wherein the projections in the second row of projections comprise a first projection and a second projection disposed closer to the distal end of the upper than the first projection, the second projection defining a greater height than the first projection.

17. The upper of claim 16, wherein the textured area further includes a third row of alternating projections and recesses extending across the upper in a third direction substantially parallel to the first direction and between the throat of the upper and the sole structure at the other of the medial side of the upper and the lateral side of the upper, each projection of the third row of alternating projections and recesses extending away from the cavity to a respective apex and defining a respective height between the co-extensive reference boundary and the respective apex, and each recess of the third row of alternating projections and recesses extending toward the cavity to a respective nadir and defining a respective depth between the co-extensive reference boundary and the respective nadir.

18. The upper of claim 17, wherein the projections in the third row of projections comprise a third projection and a fourth projection disposed closer to the sole structure than the third projection, the fourth projection defining a greater height than the third projection.

19. The upper of claim 11, wherein the upper is formed from a knitted component including a knit element and a tensile element, the tensile element attached to the knit element within the smooth area of the upper and detached from the knit element within the textured area of the upper.
