Abstract

An article of footwear includes a sole, an upper defining a foot cavity, and a brace member. The brace member is comprised of a non-elastic resilient material. The brace member is positioned within a pocket in the upper and extends from a heel portion to above an ankle portion of the upper. The brace member may be provided with a top plate member and a base plate member with a central shaft extending between the top plate member and the base plate member. The central shaft may have a C-shape that curves around an ankle of a human foot positioned within the foot cavity.

First claim

What is claimed is:

1. An article of footwear comprising:
a sole; and
a shoe upper connected to the sole, the shoe upper defining a foot cavity configured to receive a human foot, the shoe upper further defining an ankle region, a heel region, a midfoot region, and a forefoot region, the shoe upper including an elastic portion extending upward from the heel region to the ankle region;
an internal elastic wrap member integrated into the article of footwear, the entire internal elastic wrap member being disposed inside the shoe upper such that the entire elastic wrap member is oriented entirely within the foot cavity defined by the upper; and
a lace configured to tighten the shoe upper,
wherein the elastic wrap member is coupled to the elastic portion of the shoe upper such that the elastic wrap member is disposed within the ankle region, wherein the elastic wrap member is a resilient and stretchable fabric including elastane or elastic fibers, and wherein both the elastic wrap member and the elastic portion of the shoe upper stretch when the lace is engaged to tighten the shoe upper.

2. The article of footwear of claim 1 wherein the elastic wrap member includes a cradle portion configured to only partially surround the human foot.

3. The article of footwear of claim 1 , wherein: the upper further comprises an inelastic portion; and
the inelastic portion is connected to the elastic portion via a seam.

4. The article of footwear of claim 3 , wherein:
the shoe upper further includes a tongue slot extending from the inelastic portion of the upper to the elastic portion;
the slot defining tongue slot edges that are adjustable relative to each other;
adjusting the tongue slot edges relative to each other alters the compressive force applied by the elastic wrap member; and
the seam extends to a tongue slot edge.

5. The article of footwear of claim 3 , wherein:
the elastic portion comprises a lace eyelet and the inelastic portion comprises a lace of eyelet;
the seam divides the elastic portion from the inelastic portion; and
the seam is positioned between the lace eyelet of the elastic portion and the lace eyelet of the inelastic portion.

6. The article of footwear of claim 1 wherein the elastic wrap member includes a perimeter portion coupled to the shoe upper and a cradle portion, wherein at least part of the cradle portion is free floating within the foot cavity.

7. The article of footwear of claim 1 wherein the elastic wrap member covers substantially all of an inner surface of the elastic portion of the shoe upper within the foot cavity.

8. The article of footwear of claim 1 , wherein:
the upper further comprises an inelastic portion;
the lace extends from the inelastic portion of the upper to the elastic portion of the upper; and
engaging the lace tightens the inelastic portion, the elastic portion, and the elastic wrap member around the foot.

9. The article of footwear of claim 8 , wherein:
the shoe upper includes a tongue slot extending from the inelastic portion of the upper to the elastic portion of the upper;
the lace spans the tongue slot in the inelastic portion and the elastic portion; and
the lace is capable of drawing sides of the slot toward each other upon lace engagement.

10. The article of footwear of claim 1 , wherein:
the elastic portion forms the ankle region of the upper;
the elastic portion defines an outer surface and an inner, user-facing surface; and
the elastic wrap member is disposed over the elastic portion such that the wrap member spans the elastic portion inner surface.

11. The article of footwear of claim 1 , wherein:
the upper further includes a top edge oriented above the ankle; and
the elastic wrap member extends upward from the heel region, over the ankle region, and to the top edge of the upper.

12. The article of footwear of claim 11 , wherein:
the elastic wrap member terminates at the top edge of the upper; and
both the elastic portion of the upper and the elastic wrap member are within the ankle region.

13. The article of footwear of claim 1 , wherein each of the elastic wrap member and the upper is disposed over the ankle of the wearer.

14. An article of footwear comprising:
a sole;
a shoe upper connected to the sole, the shoe upper defining a foot cavity configured to receive a human foot, the shoe upper including an elastic portion comprising a lace eyelet and an inelastic portion comprising a lace eyelet; and
an elastic wrap member positioned within the foot cavity, wherein the elastic wrap member is a resilient and stretchable fabric including elastane or elastic fibers,
wherein the elastic portion of the shoe upper is connected to the inelastic portion of the shoe upper via a seam dividing the elastic portion from the inelastic portion, and wherein the seam extends between the lace eyelet of the elastic portion and the lace eyelet of the inelastic portion.

15. The article of footwear of claim 14 wherein:
the elastic portion of the shoe upper is an elastane material; and
the inelastic portion of the shoe upper is comprised of a material selected from the group consisting of leather, synthetic leather, and soft plastic.

16. The article of footwear of claim 14 wherein the elastic wrap member covers substantially all of an inner surface of the elastic portion of the shoe upper within the foot cavity.

17. The article of footwear of claim 14 , wherein the elastic portion of the shoe upper and the elastic wrap member cooperate to apply compressive force to the human foot.

18. The article of footwear of claim 14 , wherein:
the shoe upper further includes a tongue slot extending from the inelastic portion of the upper to the elastic portion of the upper, the slot defining edges adjustable relative to each other;
adjusting the edges alters the compressive force applied by the elastic wrap member; and the seam extends to an edge defined by the tongue slot.

19. The article of footwear of claim 14 , wherein the elastic portion of the upper includes a plurality of eyelets.

20. The article of footwear of claim 14 , wherein the seam is positioned between the lace eyelet of the elastic portion and the lace eyelet of the inelastic portion.
