Abstract

An upper for an article of footwear includes a first upper panel, a second upper panel, and an extruded component. The extruded component is disposed along a border between the first upper panel and the second upper panel. The extruded component joins the first upper panel to the second upper panel.

Claims

1. A method of making an article of footwear, the method comprising:

forming an upper; and

extruding a component having a first segment, a second segment, an inner surface facing the upper, and an outer surface, wherein the inner surface bonds to the upper at the first segment and does not bond to the upper at the second segment.

2. The method of claim 1, wherein a third segment of the component bonds to the upper, wherein the second segment is between the first and third segments.

3. The method of claim 2, wherein the second segment is disposed over a void in the upper.

4. The method of claim 2, wherein the second segment is disposed over a tongue region of the upper.

5. The method of claim 2, wherein the first segment is disposed on a medial side of the upper and the third segment is disposed on a lateral side of the upper.

6. The method of claim 2, wherein a portion of the upper disposed underneath the second segment is configured to move independently of the second segment.

7. The method of claim 1, wherein the upper comprises a textile fabric.

8. The method of claim 1, wherein the upper comprises a knitted fabric.

9. The method of claim 1, wherein the upper comprises one of a knit, woven, or non-woven material.

10. The method of claim 1, further comprising placing a non-stick material on the upper, wherein the second segment is formed over the non-stick material.

11. The method of claim 10, wherein the non-stick material comprises a coating.

12. The method of claim 11, further comprising removing the non-stick material.

13. The method of claim 11, wherein placing a non-stick material on the upper comprises screen printing the non-stick material on the upper.

14. The method of claim 11, wherein placing a non-stick material on the upper comprises spraying the non-stick material on the upper.

15. The method of claim 11, wherein the non-stick material is bonded to the upper.

16. The method of claim 1, wherein the component is extruded onto the upper after the upper is formed.
