Abstract

An article of footwear has an upper including a body and a unitary support frame attached to the body. A sole structure may be attached to and underlie the upper. The unitary support frame may support the body over the sole structure, and the body may define a foot-receiving cavity over the sole structure and an ankle opening in communication with the foot-receiving cavity. The unitary support frame may define a medial peak at a medial side of the article of footwear and a lateral peak at a lateral side of the article of footwear and may extend forwardly and downwardly from the medial peak and the lateral peak.

First claim

What is claimed is:

1. An article of footwear comprising:
a heel region, a forefoot region spaced apart from the heel region, and a midfoot region disposed between the heel region and the forefoot region;
an upper including a body and a unitary support frame attached to the body;
a sole structure attached to and underlying the upper;
the unitary support frame supporting the body over the sole structure, and the body defining a foot-receiving cavity over the sole structure and an ankle opening in communication with the foot-receiving cavity;
the unitary support frame defining a medial peak at a medial side of the article of footwear and a lateral peak at a lateral side of the article of footwear, and extending forwardly and downwardly from the medial peak and from the lateral peak and around the ankle opening;
wherein the unitary support frame is configured as an arch over the sole structure forward of the ankle opening that extends from the lateral side to the medial side to suspend the body over the sole structure and inhibit collapse of the body toward the sole structure;
wherein the unitary support frame is directly attached to the sole structure at the midfoot region and the heel region and is not directly attached to the sole structure at the forefoot region;
wherein the upper comprises a front section and a hinged heel section, the front section includes the body, and the hinged heel section is pivotable relative to the body at a rear of the heel region;
wherein the upper comprises an elastic heel band extending around the hinged heel section from the medial side to the lateral side;
wherein the elastic heel band extends upwardly and rearwardly from the front section at the medial side and at the lateral side at a first angle relative to a horizontal plane; and
wherein the unitary support frame includes a medial arm extending forwardly under the medial peak and a lateral arm extending forwardly under the lateral peak, an edge of the medial arm and an edge of the lateral arm extending upwardly and rearwardly from the sole structure at the first angle relative to the horizontal plane.

2. The article of footwear of claim 1 , wherein the unitary support frame has a first medial segment extending upwardly and forwardly on the medial side to the medial peak, a first lateral segment extending upwardly and forwardly on the lateral side to the lateral peak, and a front segment extending downwardly and forwardly from the medial peak and the lateral peak.

3. The article of footwear of claim 2 , wherein the front segment defines a front peak disposed over a central top region of the body and forward of the ankle opening.

4. The article of footwear of claim 1 , wherein the unitary support frame has a front segment disposed forward of the ankle opening, and the article of footwear further comprising:
padding secured to the body and extending rearward of the front segment of the unitary support frame to a forward edge of the ankle opening, wherein the padding is thicker than the body.

5. The article of footwear of claim 4 , wherein a portion of the body is disposed forward of the front segment of the unitary support frame and is characterized by an absence of padding.

6. The article of footwear of claim 4 , wherein the padding extends upwardly and rearwardly of the front segment of the unitary support frame and partially defines a tongue.

7. The article of footwear of claim 6 , wherein the body comprises a first material disposed forward of the front segment of the unitary support frame, and a second material disposed rearward of the front segment of the unitary support frame to the ankle opening, the second material further defining the tongue.

8. The article of footwear of claim 1 , wherein the unitary support frame extends continuously from the sole structure at the medial side in the heel region of article of footwear, over the foot-receiving cavity forward of the ankle opening, and to the sole structure at the lateral side in the heel region.

9. The article of footwear of claim 1 , wherein the unitary support frame includes a base extending along the sole structure at a rear of the heel region of the article of footwear from the lateral side to the medial side.

10. The article of footwear of claim 9 , wherein:
the unitary support frame has a first medial segment extending upwardly and forwardly on the medial side to the medial peak, and a first lateral segment extending upwardly and forwardly on the lateral side to the lateral peak; and
the first lateral segment and the first medial segment extend upwardly from the base.

11. The article of footwear of claim 10 , wherein the base includes a medial arm extending forwardly under the first medial segment, and a lateral arm extending forwardly under the first lateral segment.

12. The article of footwear of claim 11 , wherein:
the medial arm tapers in a forward direction of the article of footwear to a medial extremity in the midfoot region of the article of footwear; and
the lateral arm tapers in the forward direction to a lateral extremity in the midfoot region.

13. The article of footwear of claim 9 , wherein the unitary support frame includes a heel support segment that extends upwardly from the base at the rear of the heel region.

14. The article of footwear of claim 1 , wherein the upper comprises a first pull loop secured to the front section forward of the ankle opening, and a second pull loop secured to the hinged heel section rearward of the ankle opening.

15. The article of footwear of claim 1 , wherein an exterior surface of the body is impermeable to liquid.

16. The article of footwear of claim 1 , wherein the body comprises natural or synthetic leather.

17. The article of footwear of claim 1 , wherein the unitary support frame is attached to an exterior surface of the body.

18. An article of footwear comprising:
a heel region, a forefoot region spaced apart from the heel region, and a midfoot region disposed between the heel region and the forefoot region;
an upper including a body and a unitary support frame attached to the body;
a sole structure attached to and underlying the upper;
the unitary support frame supporting the body over the sole structure, and the body defining a foot-receiving cavity over the sole structure and an ankle opening in communication with the foot-receiving cavity;
the unitary support frame defining a medial peak at a medial side of the article of footwear and a lateral peak at a lateral side of the article of footwear, and extending forwardly and downwardly from the medial peak and from the lateral peak and around the ankle opening;
wherein the unitary support frame is configured as an arch over the sole structure forward of the ankle opening that extends from the lateral side to the medial side to suspend the body over the sole structure and inhibit collapse of the body toward the sole structure;
wherein the unitary support frame is directly attached to the sole structure at the midfoot region and the heel region and is not directly attached to the sole structure at the forefoot region;
wherein the unitary support frame includes a base extending along the sole structure at a rear of the heel region of the article of footwear from the lateral side to the medial side, the upper comprises a front section and a hinged heel section, the front section includes the body, and the hinged heel section is pivotable relative to the body at the rear of the heel region;
wherein the upper comprises an elastic heel band extending around the hinged heel section from t
