Abstract

An article of footwear having an upper comprising leno woven fabric. The leno woven fabric may be a single layer leno woven fabric. The leno woven fabric may have a pattern to provide desired characteristics, such as but not limited to, ventilation, thermal conductivity, stretchability, strength, moisture wicking, and/or antimicrobial protection. The pattern may be non-uniform to provide varying degrees of one or more of these characteristics. Methods for manufacturing an article of footwear including an upper comprising leno woven fabric are also provided.

First claim

What is claimed is:

1. An article of footwear comprising:
a sole;
an upper coupled to the sole, the upper comprising:
a first portion comprising a single layer woven fabric comprising a lend weave configuration comprising a plurality of weft yarns extending in a longitudinal direction from a forefoot portion of the article of footwear towards a heel portion of the article of footwear and a plurality of warp yarns extending in a transverse direction substantially perpendicular to the warp yarns; and
a second portion comprising a heel counter,

wherein one or more weft yarns includes a first end coupled to the second portion and a second end coupled to the sole of the article of footwear.

2. The article of footwear of claim 1 , wherein the single layer woven fabric is directly coupled to the sole.

3. The article of claim 1 , wherein the single layer woven fabric includes a continuous portion extending from the forefoot portion of the article of footwear to a midfoot portion of the article of footwear.

4. The article of footwear of claim 1 , wherein the single layer woven fabric includes a continuous portion extending from the forefoot portion of the article of footwear to the heel portion of the article of footwear.

5. The article of footwear of claim 1 , wherein the single layer woven fabric includes a continuous portion extending from a lateral side of the article of footwear to a medial side of the article of footwear.

6. The article of footwear of claim 1 , wherein one or more of the warp yarns includes a first end directly coupled to the sole and a second end directly coupled to the sole.

7. The article of footwear of claim 1 , wherein one or more of the warp yarns includes a first end directly coupled to a lateral side of the sole and a second end directly coupled to a medial side of the sole.

8. The article of footwear of claim 1 , wherein the single layer woven fabric defines at least 50% of the upper.

9. The article of footwear of claim 1 , wherein the weft yarns comprise at least one of: a moisture wicking yarn, an antibacterial yarn, a thermally conductive yarn, and a combination thereof.

10. The article of footwear of claim 1 , wherein the leno weave configuration comprises a non-uniform pattern.

11. The article of footwear of claim 1 , wherein the leno weave configuration comprises a non-uniform honeycomb pattern.

12. The article of footwear of claim 1 , wherein the weft yarns are arranged in sets of at least two yarns arranged side-by-side along at least a portion of the upper.

13. The article of footwear of claim 12 , wherein the set of weft yarns splits at one or more points on the upper to provide at least one of: ventilation for the upper and directional stretchability for the upper.

14. The article of footwear of claim 1 , wherein the second portion further comprises an ankle cuff and a tongue.

15. The article of footwear of claim 1 , wherein the single layer woven fabric is a continuous layer having varying degrees of at least one of: ventilation, thermal conductivity, stretchability, strength, moisture wicking, and antimicrobial protection.

16. An article of footwear comprising:
a sole; and
an upper coupled to the sole; the upper comprising a leno woven fabric comprising a plurality of weft yarns extending in a substantially longitudinal direction from a forefoot portion of the article of footwear towards a heel portion of the article of footwear and a plurality of warp yarns extending in a transverse direction substantially perpendicular to the warp yarns;
wherein the leno woven fabric comprises a continuous leno weave pattern extending from the forefoot portion of the upper to a midfoot portion of the upper, and
wherein the continuous leno weave pattern comprises a pattern that varies a characteristic of the leno woven fabric by varying the spacing between at least one of the weft yarns and the warp yarns to provide targeted degrees of the characteristic to different areas in the forefoot portion and the midfoot portion of the upper.

17. The article of footwear of claim 16 , wherein the leno woven fabric defines at least 50% of the outer surface area of the upper.

18. The article of footwear of claim 16 , wherein the leno woven fabric is directly coupled to the sole.

19. A method of manufacturing an article of footwear, the method comprising:
coupling a single layer woven fabric to a footwear component comprising a heel counter, the single layer woven fabric comprising a lend weave configuration comprising a plurality of weft yarns extending in a longitudinal direction from a forefoot portion of the article of footwear towards a heel portion of the article of footwear and a plurality of warp yarns extending in a transverse direction substantially perpendicular to the warp yarns;
coupling the single layer woven fabric to a sole, wherein one or more weft yarns includes a first end coupled to the footwear component and a second end coupled to the sole; and
coupling the heel counter to the sole.

20. The article of footwear of claim 16 ; wherein the characteristic is selected from the group consisting of: ventilation, thermal conductivity, stretchability, strength, moisture wicking, and antimicrobial protection.
