Abstract

An article of footwear and a method of manufacturing the article of footwear are disclosed. The footwear may include an upper and a sole structure. The upper incorporates a textile element with edges that are joined together to define at least a portion of a void for receiving a foot. The textile element may have a first area with a first property and a second area with a second property. Various warp or weft knitting processes, including flat knitting, may be utilized to form the textile element.

Claims

1. An upper for an article of footwear, the upper comprising:

a flat knit textile element comprising (1) flat knit edges free of surrounding textile structure such that the flat knit edges are not surrounded by textile structure from which the textile element must be removed, at least one flat knit edge being a curved flat knit edge, and (2) a first knit strip having a first property and a second knit strip having a second property that is different from the first property;

wherein the first knit strip and the second knit strip are positioned adjacent to each other along one or more of a lateral side and a medial side of the upper.

2. The upper of claim 1, wherein one or both of the first knit strip and the second knit strip comprises a plurality of knit strips.

3. The upper of claim 2, wherein the first and second knit strips alternate with one another along one or more of the lateral side and the medial side of the upper.

4. The upper of claim 2, wherein the flat knit textile element comprises at least two first knit strips and at least two second knit strips.

5. The upper of claim 1, wherein the first knit strip and the second knit strip extend along the lateral side of the upper from an instep region of the upper to an area proximate to a lower region of the upper.

6. The upper of claim 1, wherein the first knit strip and the second knit strip extend along the medial side of the upper from an instep region of the upper to an area proximate to a lower region of the upper.

7. The upper of claim 1, wherein the first property comprises a first knit construction and the second property comprises a second knit construction.

8. The upper of claim 1, wherein the first property of the first knit strip comprises a smooth texture, and the second property of the second knit strip comprises a rough texture.

9. The upper of claim 1, wherein the flat knit textile element further comprises a plurality of apertures in an instep region of the upper.

10. The upper of claim 1, wherein the first property of the first knit strip comprises a higher degree of stretch than the second property of the second knit strip.

11. The upper of claim 1, wherein the second property of the second knit strip comprises a higher degree of stretch than the first property of the first knit strip.

12. The upper of claim 1, wherein the first property comprises a first yarn type and the second property comprises a second yarn type.

13. The upper of claim 12, wherein the first yarn type of the first knit strip comprises at least one of a higher biodegradability, moisture absorption, insulation, durability, and/or hydrophobicity than the second yarn type of the second knit strip.

14. The upper of claim of claim 12, wherein the first yarn type of the first knit strip comprises at least one of a higher strength, support, stiffness, recovery, fit and/or form than the second yarn type of the second knit strip.

15. An article of footwear comprising:

an upper comprising;

a flat knit textile element comprising (1) flat knit edges free of surrounding textile structure such that the flat knit edges are not surrounded by textile structure from which the textile element must be removed, at least one flat knit edge being a curved flat knit edge, and (2) a first knit strip having a first property and a second knit strip having a second property that is different from the first property;

wherein the first knit strip and the second knit strip are positioned adjacent to each other along one or more of a lateral side and a medial side of the upper; and

a sole structure secured to the upper.

16. The article of footwear of claim 15, wherein the first property comprises one or more of a first knit construction and a first yarn type and wherein the second property comprises one or more of a first knit construction and a second yarn type.

17. The article of footwear of claim 15, wherein the flat knit textile element comprises a plurality of first knit strips extending along the lateral side and the medial side of the upper and a plurality of second knit strips extending along the lateral side and the medial side of the upper.

18. The article of footwear of claim 15, wherein the first knit strip is parallel to the second knit strip.

19. The article of footwear of claim 15, wherein the first knit strip and the second knit strip extend along the lateral side of the upper from an instep region of the upper to an area proximate to the sole structure.

20. The article of footwear of claim 15, wherein the first knit strip and the second knit strip extend along the medial side of the upper from an instep region of the upper to an area proximate to the sole structure.
