Abstract

An article of footwear includes an upper incorporating a knitted component formed of unitary knit construction. The knitted component includes areas formed using monofilament strands. The monofilament areas may be bounded by multifilament areas. The multifilament areas may be configured to form a welt that includes a tensile element.

First claim

What is claimed is:

1. An article of footwear comprising:
a knitted component including at least one monofilament area comprised of a monofilament strand, the at least one monofilament area having a shape;
a first multifilament area adjacent to the at least one monofilament area, the first multifilament area comprising at least two overlapping knit layers of multifilament yarn, wherein the at least two overlapping knit layers form a first unsecured area there between;
a second multifilament area adjacent to the at least one monofilament area;
wherein the first multifilament area and the second multifilament area define at least a portion of the shape of the at least one monofilament area; and
a first tensile element extending through at least a portion of the first unsecured area.

2. The article according to claim 1 , wherein the at least one monofilament area comprises a width and wherein the width of the at least one monofilament area is at least two courses.

3. The article according to claim 1 , wherein the first multifilament area includes an interior layer and an exterior layer, and wherein the interior layer and the exterior layer are at least partially connected to each other to form the first unsecured area.

4. The article according to claim 3 , wherein the interior layer and the exterior layer contact the first tensile element.

5. The article according to claim 3 , wherein the exterior layer includes a first number of courses and the interior layer includes a second number of courses, the first number of courses being greater than the second number of courses.

6. The article according to claim 3 , wherein the at least one monofilament area is located in a first plane and the exterior layer of the first multifilament area is located in a second plane, the first plane being located closer to a foot.

7. The article according to claim 1 , wherein the at least one monofilament area defines a width, the first multifilament area defines a width, and wherein the width of the at least one monofilament area is less than the width of the first multifilament area.

8. The article according to claim 1 , wherein the first tensile element forms a lace loop.

9. The article of claim 1 wherein the second multifilament area comprises at least two overlapping knit layers of multifilament yarn, wherein the at least two overlapping knit layers form a second unsecured area there between.

10. The article according to claim 9 , wherein the first tensile element extends from the first unsecured area into the second unsecured area.

11. The article of claim 9 wherein a second tensile element extends through at least a portion of the second unsecured area.

12. The article of claim 1 further comprising an instep border portion and a sole border portion and wherein the instep border portion and the sole border portion further define at least a portion of the shape of the at least one monofilament area.

13. The article according to claim 1 wherein the first unsecured area comprises a tubular structure through which the first tensile element extends.

14. The article according to claim 3 wherein the interior layer and the exterior layer of the first unsecured area provide a barrier between the first tensile element and the at least one monofilament area.

15. The article according to claim 1 wherein the first multifilament area is disposed on at least a portion of an outer surface of the at least one monofilament area.

16. The article according to claim 9 , wherein the first tensile element extends along a length the first unsecured area two times.

17. An article of footwear comprising:
a knitted component comprising
a plurality of monofilament areas comprising a monofilament strand, the plurality of monofilament areas comprising a shape;
a plurality of multi filament areas comprising at least two overlapping knit layers of multifilament yarn, wherein the at least two overlapping knit layers comprise an interior layer and an exterior layer and wherein the plurality of multifilament areas define at least a portion of the shape of the plurality of monofilament areas;
wherein the plurality of monofilament areas are located in a first plane and wherein at least the exterior layer of the plurality of multifilament areas is located in a second plane.

18. The article of claim 16 wherein the second plane is located radially outwardly of the first plane.
