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. A shoe comprising:

an upper having top and bottom layers of material or a flap having an internal pocket; and

a device for protecting the metatarsal region of a user'"'"'s foot, the device being situated between the top and bottom layers of the upper or within the internal pocket, wherein the device comprises;

a first layer of material having top and bottom surfaces and a series of cones formed into at least one of the top and bottom surfaces, the series of cones including individual cones of varying depth and width; and

a second layer of material overlying the first layer and having a rigidity that is higher than a rigidity of the first layer, the first layer being shaped to conform to the metatarsal region of the user'"'"'s foot, such that the device is configured to provide protection for the metatarsal region against injurious events,

wherein first and second series of cones are formed into the top and bottom surfaces of the first layer of material, respectively, the first and second series including a first set of cones having a second depth and width, and a second set of cones having a second depth and width, the first depth and width being greater than the second depth and width.

2. The shoe of claim 1, wherein individual cones within the first set alternate with individual cones within the second set on both the top and bottom surfaces of the first layer of material.

3. The shoe of claim 2, wherein the first series of cones is offset with respect to the second series of cones, such that a terminal end of at least one cone within the first series is situated adjacent a terminal end of at least one cone within the second series.

4. The shoe of claim 1, wherein the second layer is situated within a recess formed in the top surface of the first layer, the second layer including a pattern of hexagons.

5. The shoe of claim 4, wherein the pattern of hexagons includes a first set of outer hexagons extending from an outer surface of the second layer, such outer hexagons being defined by a perimeter, and a second set of inner hexagons situated within the perimeter and extending towards the outer surface of the second layer.

6. The shoe of claim 5, wherein the outer hexagons comprising the first set include walls defining each hexagon, such walls being angled in one direction, and the inner hexagons comprising the second set include walls defining each hexagon, such walls being angled in another direction.

7. The shoe of claim 6, wherein an inner surface of the second layer is convex in a longitudinal direction and concave in a medial-lateral direction.

8. The shoe of claim 1, wherein the second layer is adhered to the top surface of the first layer, the second layer including inner and outer surfaces that are generally non-patterned.

9. The shoe of claim 4, wherein the second layer exhibits rigidity when bent in one direction, and reacts with relative flexibility when bent in another opposing direction.

10. A shoe comprising:

an upper having top and bottom layers of material or a flap having an internal pocket; and

a device for protecting the metatarsal region of a user'"'"'s foot, the device being situated between the top and bottom layers of the upper or within the internal pocket, wherein the device comprises;

a first layer of material having top and bottom surfaces, at least one of the top and bottom surfaces including a first pattern of hexagons formed thereon; and

a second layer of material overlying the first layer and having a rigidity that is greater than a rigidity of the first layer, the first layer being shaped to conform to the metatarsal region of the user'"'"'s foot, such that the device is configured to provide protection for the metatarsal region against injurious events,

wherein the second layer exhibits rigidity when bent in one direction, and reacts with relative flexibility when bent in another opposing direction.

11. The shoe of claim 10, wherein the first pattern of hexagons includes a first set of outer hexagons extending from the bottom surface of the first layer of material, such outer hexagons being defined by a perimeter, and a second set of inner hexagons situated within the perimeter and extending towards the bottom surface of the first layer.

12. The shoe of claim 11, wherein the outer hexagons comprising the first set include walls defining each hexagon, such walls being angled in one direction, and the inner hexagons comprising the second set include walls defining each hexagon, such walls being angled in another direction.

13. The shoe of claim 12, wherein the bottom surface of the first layer of material is convex in a longitudinal direction and concave in a medial-lateral direction.

14. The shoe of claim 10, wherein the second layer is situated within a recess formed in the top surface of the first layer, the second layer including a second pattern of hexagons.

15. The shoe of claim 14, wherein the second pattern of hexagons includes a first set of outer hexagons extending from an outer surface of the second layer, such outer hexagons being defined by a perimeter, and a second set of inner hexagons situated within the perimeter and extending towards the outer surface of the second layer.

16. The shoe of claim 10, wherein the second layer is adhered to the top surface of the first layer, the second layer including inner and outer surfaces that are generally non-patterned.

17. The shoe of claim 10, wherein the first pattern of hexagons is formed only on the bottom surface of the first layer of material.
