Abstract

An article of footwear includes a sole, an upper connected to the sole, and a support framework. The upper defines a foot cavity configured to receive a human foot. The upper further defines an ankle region, a heel region, a midfoot region, and a forefoot region. The upper also includes an inner layer and an outer layer. The support framework is integrated into the ankle region of the article of footwear. The support framework includes a plurality of substantially vertical support members traversing a plurality of substantially horizontal support members at intersections. A plurality of tensioning members are positioned on the upper in association with a tongue slot, wherein each of the substantially horizontal support members is coupled to one of the plurality of tensioning members.

First claim

What is claimed is:

1. An article of footwear comprising:
a sole;
an upper coupled to the sole, the upper defining a foot cavity configured to receive a human foot, the upper further defining an ankle region, a heel region below the ankle region, a midfoot region forward the heel region, and a forefoot region forward the midfoot region, wherein the upper comprises:
a first layer,
a second layer,
a plurality of elongated channels formed between the first layer and the second layer,
a support framework positioned between the first layer and the second layer, the support framework comprising:
a plurality of stiffening supports extending upward from the sole, across the ankle region and towards a top of the article of footwear, and
a plurality of tensioning members extending through the plurality of elongated channels formed between the first layer and the second layer, each of the plurality of tensioning members associated with one of the plurality of elongated channels and moveable within said associated channel, wherein each of the plurality of stiffening supports crosses each of the plurality of channels, and wherein at least one of the plurality of tensioning members overlaps each of the plurality of stiffening supports within at least one of the elongated channels; and

a lacing system positioned on the upper.

2. The article of footwear of claim 1 , wherein a width of one or more of the plurality of stiffening supports tapers along its length.

3. The article of footwear of claim 1 , wherein each of the first layer of the upper and the second layer of the upper includes an elastic material that comprises elastane or elastic fibers.

4. The article of footwear of claim 1 wherein said at least one of plurality of tensioning members overlaps said lacing system, wherein said at least one of plurality of tensioning members comprises a band formed from elastic material, inelastic material, or both, and wherein each of said elongated channels has a shape corresponding to an associated one of the plurality of tensioning members.

5. An article of footwear comprising:
a sole; and
an upper coupled to the sole, the upper having a forefoot region, a midfoot region rearward of the forward region, a heel region rearward of the midfoot region, an ankle region above the heel region, and an upper foot region above the ankle region, wherein the upper further comprises:
a plurality of individual channels, each channel of the plurality of channels comprising a first layer stitched to a second layer, and each channel of the plurality of channels defined by a length and a width wherein the length is greater than the width; and
a support framework comprising a plurality of elongated stiffening supports and a plurality of elongated tensioning members, each of the stiffening supports and each of the tensioning members defined by a length and a width wherein the length is greater than the width, each tensioning member of the plurality of tensioning members i) housed within an associated channel of the plurality of channels, ii) extending lengthwise along said associated channel, and iii) moveable within said associated channel with said associated channel operable to guide said tensioning member of the plurality of the tensioning members during tightening of the upper on a foot, wherein one or more of the plurality of tensioning members is moveably housed within its associated channel during tightening of the upper on the foot; and
each of said plurality of stiffening supports extending upward from the sole and across the ankle region, each of said plurality of stiffening supports overlapping each of said plurality of tensioning members within said associated channel of the plurality of channels.

6. The article of footwear of claim 5 , wherein the plurality of channels are located within the upper foot region of the upper, the article of footwear further comprising a lacing system positioned on the upper, wherein the lacing system is configured to tighten the upper on the foot.

7. The article of footwear of claim 6 , wherein a first channel of the plurality of channels extends along a lateral side of the upper and a second channel of the plurality of channels extends along a medial side of the upper.

8. The article of footwear of claim 5 , wherein the sole is a cleated sole and wherein the plurality of channels are located within the midfoot region of the upper, extending upward from the cleated sole.

9. The article of footwear of claim 5 , wherein at least one of the plurality of tensioning members comprises an inelastic fabric band.

10. The article of footwear of claim 5 , wherein each of the first layer and the second layer comprises fabric.

11. The article of footwear of claim 5 , wherein the plurality of channels are arranged in spaced relation along the second layer.

12. The article of footwear of claim 11 , wherein:
the second layer forms an inner layer of the upper; and
the upper further comprises an outer shell forming an exterior of the upper.

13. The article of footwear of claim 12 , wherein the sole is a cleated sole.

14. The article of footwear of claim 5 , wherein each of the plurality of tensioning members comprises a strap formed from elastic material, inelastic material, or both.

15. The article of footwear of claim 1 wherein the plurality of tensioning members are elongated in shape.
