Abstract

An upper may include a reinforced panel. The panel may comprise a carrier, inner reinforcing strips and outer reinforcing strips. The inner and outer reinforcing strips may be respectively bonded to interior and exterior faces of the carrier. Each of the inner reinforcing strips may be approximately parallel to at least one adjacent inner reinforcing strip and separated from that at least one adjacent inner reinforcing strip by one or more unreinforced portions of the carrier interior face. Each of the outer reinforcing strips may be approximately parallel to at least one adjacent outer reinforcing strip and separated from that at least one adjacent outer reinforcing strip by one or more unreinforced portions of the carrier exterior face.

Claims

1. An article of footwear comprising:

an upper having a reinforced panel forming a portion of the upper extending from at least a medial heel region, around a rear of the upper, and to at least a lateral heel region, the reinforced panel further comprising

a carrier having interior and exterior faces,

a set of first reinforcing strips bonded to the exterior face of the carrier, wherein each of the first reinforcing strips is approximately parallel to at least one adjacent first reinforcing strip and surrounded on both sides along its entire length by unreinforced portions of the carrier exterior face,

a set of second reinforcing strips bonded to the interior face of the carrier, wherein each of the second reinforcing strips is approximately parallel to at least one adjacent second reinforcing strip and surrounded on both sides along its entire length by unreinforced portions of the carrier interior face,

wherein each of the first reinforcing strips is oriented so as to intersect at least one of the second reinforcing strips and to form acute angles at the intersections, each of the first reinforcing strips includes at least one portion overlapping an unreinforced portion of the carrier interior face, and each of the second reinforcing strips includes at least one portion overlapping an unreinforced portion of the carrier exterior face,

wherein each of the first and second reinforcing strips comprises a sheet of material,

wherein multiple first and second reinforcing strips are positioned along each of a medial side and a lateral side of the carrier, and along a rearmost side of a heel portion of the carrier, and

wherein a top end of each reinforcing strip is spaced from a top edge of the upper and a bottom end of each reinforcing strip is spaced from a bottom edge of the upper.

2. The article of footwear of claim 1, wherein the carrier comprises a mesh material.

3. The article of footwear of claim 2, wherein the carrier is a single piece of the mesh material.

4. The article of footwear of claim 1, wherein each of the first reinforcing strips and each of the second reinforcing strips has a length along a dimension extending between top and bottom edges of the reinforced panel and an average width exceeded by the length.

5. The article of footwear of claim 1, wherein the set of first reinforcing strips comprises at least 10 first reinforcing strips and the set of second reinforcing strips comprises at least 10 second reinforcing strips.

6. The article of footwear of claim 1, wherein the set of first reinforcing strips comprises at least 20 first reinforcing strips and the set of second reinforcing strips comprises at least 20 second reinforcing strips.

7. The article of footwear of claim 1, wherein

at least a portion of the first reinforcing strips on the lateral side have orientations angled acutely from the vertical and toward a front of the article,

at least a portion of the first reinforcing strips on the medial side have orientations angled acutely from the vertical and toward the front of the article, and

at least a portion of the second reinforcing strips on the lateral side have orientations angled acutely from the vertical and toward a rear of the article.

8. The article of footwear of claim 6, wherein at least a portion of the second reinforcing strips on the medial side have orientations angled acutely from the vertical and toward a front of the article.

9. The article of footwear of claim 1, wherein the reinforced panel forms a portion of the upper extending from at least the medial heel region, around the rear of the upper, and to at least a lateral midfoot region.

10. The article of footwear of claim 1, wherein the first and the second reinforcing strips are formed from polyurethane coated thermoplastic polyurethane film.

11. The article of footwear of claim 1, further comprising a sole structure, and wherein

each of the first reinforcing strips extends from a first bottom band to a first top band,

the first bottom band is in a region of the upper adjacent the sole structure and the first top band is in a region of the upper adjacent to tongue and ankle openings of the upper,

each of the second reinforcing strips extends from a second bottom band to a second top band, and

the second bottom band is in a region of the upper located in a lower region of a void defined in part by the upper and the second top band is in a region of the upper adjacent to the tongue and ankle openings.

12. The article of footwear of claim 11, wherein

the bottom end of each of the first reinforcing strips joins the first bottom band and the top end of each of the first reinforcing strips joins the first top band,

as to each of a portion of the first reinforcing strips located on a lateral side of the upper, the bottom end is located rearward of the top end,

as to each of a portion of the first reinforcing strips located on a medial side of the upper, the bottom end is located rearward of the top end,

each of the second reinforcing strips has a bottom end joining the second bottom band and a top end joining the second top band,

as to each of a portion of the second reinforcing strips located on the lateral side of the upper, the bottom end is located forward of the top end.

13. The article of footwear of claim 12, wherein, as to each of a portion of the second reinforcing strips located on the medial side of the upper, the bottom end is located rearward of the top end.

14. The article of footwear of claim 11, wherein

the first reinforcing strips, the first top band, and the first bottom band are portions of an integral element fused to the carrier, and

the second reinforcing strips, the second top band, and the second bottom band are portions of an integral element fused to the carrier.

15. The article of footwear of claim 14, wherein the carrier comprises a woven polyester mesh.

16. The article of footwear of claim 14, wherein

each of the first reinforcing strips has a bottom end joining the first bottom band and a top end joining the first top band,

as to each of a portion of the first reinforcing strips located on a lateral side of the upper, the bottom end is located rearward of the top end,

as to each of a portion of the first reinforcing strips located on a medial side of the upper, the bottom end is located rearward of the top end,

each of the second reinforcing strips has a bottom end joining the second bottom band and a top end joining the second top band,

as to each of a portion of the second reinforcing strips located on the lateral side of the upper, the bottom end is located forward of the top end.

17. The article of footwear of claim 11, wherein the carrier comprises a woven polyester mesh.

18. The article of footwear of claim 1, wherein the multiple first and second reinforcing strips are positioned so as to wrap continuously along the carrier from the medial side, around the heel portion, and to the lateral side of the carrier.
