Abstract

A variety of devices for protecting a user'"'"'s foot from injury are disclosed. In one embodiment, the device may be a metatarsal protection device, which may include a first layer of material having top and bottom surfaces, with at least one of such surfaces including a series of cones or a pattern of hexagons thereon. The metatarsal protection device may also include a second relatively rigid layer of material overlying the first layer, and the first layer may be shaped to conform to the metatarsal region of the user'"'"'s foot, such that the device is configured to protect the metatarsal region against injury. Other configurations and variations of a metatarsal protection device are also disclosed, as are other uses for the principles of the invention(s) disclosed herein (e.g., protection devices for other areas of the foot, etc.).

Claims

1. An article of footwear, comprising:

a sole having a first surface configured to contact a ground area and a second surface configured to support a wearer'"'"'s foot;

an upper affixed to the sole, the upper including an exterior surface and an interior surface opposite the exterior surface, the interior surface and the second surface of the sole defining a receptacle for receiving a wearer'"'"'s foot, the upper having a toe box region along a front of the article of footwear, an insertion region including an opening, adapted to receive the wearer'"'"'s foot, remote from the toe box region, and an anchor on a first side of the exterior surface of the upper adjacent the opening and configured to receive a lace; and

a metatarsal guard member housed within a flap and arranged adjacent to the exterior surface of the upper between the toe box region and the insertion region, the flap having a first end connected to the toe box region of the upper and a second end remote from the first end, the flap comprising;

a cushion layer having a first side and a second side opposite the first side, the first side of the cushion layer facing the exterior surface of the upper;

a rigid layer having a first side and a second side, the first side of the rigid layer being connected to the second side of the cushion layer, the second side of the rigid layer facing away from the exterior surface of the sole, and the rigid layer having a rigidity that is higher than a rigidity of the cushion layer; and

an eyelet on a first side of the second end of the flap and extending through the cushion layer and the rigid layer, the first side of the second end of the flap being aligned with the first side of the exterior surface of the upper, such that the lace is receivable through the eyelet and the anchor to adjustably secure the flap housing the metatarsal guard member to the insertion region of the upper.

2. The article of footwear of claim 1, wherein the flap of the metatarsal guard is convex along a longitudinal direction and concave along a medial-lateral direction of the article of footwear.

3. The article of footwear of claim 1, wherein the first side of the rigid layer is adhered to the second side of the cushion layer.

4. The article of footwear of claim 1, further comprising the lace.

5. The article of footwear of claim 1, wherein the cushioning layer and the rigid layer are both situated within a pocket of the flap.

6. The article of footwear of claim 5, wherein the cushioning layer and the rigid layer are integrally attached to the pocket of the flap.

7. The article of footwear of claim 1, wherein one of the first and second sides of the rigid layer includes a series of raised segments therealong.

8. The article of footwear of claim 7, wherein the series of raised segments extend along a medial-lateral direction of the article of footwear.

9. The article of footwear of claim 1, wherein one of the first and second sides of the rigid layer includes a series of recesses therealong.

10. The article of footwear of claim 9, wherein the series of recesses extend along a medial-lateral direction of the article of footwear.

11. The article of footwear of claim 1, wherein the cushion layer includes a series of cushioning elements arranged along at least one of the first side and the second side thereof.

12. The article of footwear of claim 11, wherein the series of cushioning elements comprises conic, hexagonal, or frustrum-shaped cushioning elements.

13. The article of footwear of claim 1, wherein one of the first and second sides of the rigid layer includes a series of recesses theralong.

14. The article of footwear of claim 13, wherein the series of recesses extend along a medial-lateral direction of the article of footwear.

15. The article of footwear of claim 1, wherein the anchor is a first anchor and the upper further comprises:

a second anchor on the first side of the exterior surface of the upper adjacent the opening, wherein the first anchor is aligned with the second anchor.

16. The article of footwear of claim 15, wherein the aligned first and second anchors have aligned receptacles along a same direction to receive the lace therethrough.

17. An article of footwear, comprising:

a sole having a first surface configured to contact a ground area and a second surface configured to support a wearer'"'"'s foot;

a lace;

an upper affixed to the sole, the upper including an exterior surface and an interior surface opposite the exterior surface, the interior surface and the second surface of the sole defining a receptacle for receiving a wearer'"'"'s foot, the upper having a toe box region along a front of the article of footwear, an insertion region including an opening, adapted to receive the wearer'"'"'s foot, remote from the toe box region, and a plurality of anchors on a first side of the exterior surface of the upper adjacent the opening, wherein each of the plurality of anchors are adaptable to receive the lace; and

a metatarsal guard member arranged adjacent to the exterior surface of the upper between the toe box region and the insertion region, the metatarsal guard member having a first end affixed to the toe box region of the upper and a second end remote from the first end, the metatarsal guard member comprising;

a cushion layer having a first side and a second side opposite the first side, the first side of the cushion layer facing the exterior surface of the upper;

a rigid layer having a first side and a second side, the first side of the rigid layer being connected to the second side of the cushion layer, the second side of the rigid layer facing away from the exterior surface of the sole, and the rigid layer having a rigidity that is higher than a rigidity of the cushion layer; and

an eyelet on a first side of the second end of the metatarsal guard member, the first side of the second end of the metatarsal guard member being aligned with first side of the exterior surface of the upper, the eyelet extending through the cushion layer and the rigid layer, such that the lace wraps through the eyelet and at least one of the plurality of anchors to adjustably secure the metatarsal guard member to the insertion region of the upper.

18. The article of footwear of claim 17, wherein the cushion layer and the rigid layer are convex along a longitudinal direction and concave along a medial-lateral direction of the article of footwear.

19. The article of footwear of claim 17, wherein the first side of the rigid layer is adhered to the second side of the cushion layer.

20. The article of footwear of claim 17, wherein one of the first and second sides of the rigid layer includes a series of raised segments therealong.

21. The article of footwear of claim 20, wherein the series of raised segments extend along a medial-lateral direction of the article of footwear.
