Abstract

A rapid-entry and rebounding fit shoe having one or both of a rapid-entry heel element and a rapid-entry tongue element and both snap back for fit. The rapid-entry shoe directs a user'"'"'s foot into or otherwise accommodates a user'"'"'s foot with respect to, a shoe opening, and thereafter secures a rear portion of rapid-entry shoe about a user'"'"'s heel as well as forefoot.

Claims

1. A rapid-entry shoe, comprising:

a heel piece comprising a first paddle coupled to a second paddle by a neck, wherein the heel piece is adapted to be located at a rear portion of the rapid-entry shoe;

a first anchor and a second anchor, each disposed beneath the footbed of the shoe, wherein the first anchor is disposed on a medial side of the rapid-entry shoe and wherein the second anchor is disposed on a lateral side of the rapid-entry shoe;

a first deformable element extending from beneath the footbed of the shoe and between the first anchor and the first paddle, wherein torsion of the first deformable element about its longitudinal axis facilitates outward rotation of the first paddle; and

a second deformable element extending from beneath the footbed of the shoe and between the second anchor and the second paddle, wherein torsion of the second deformable element about its longitudinal axis facilitates outward rotation of the second paddle;

wherein the shoe comprises a collapsed configuration and an uncollapsed configuration, wherein in the collapsed configuration at least one of the first deformable element and the second deformable element is in a compressed state and bends downward and in the uncollapsed configuration at least one of the first deformable element and the second deformable element is oriented upwards and is in a partially compressed state,

wherein in the collapsed configuration the first paddle and the second paddle are rotated outward and the first paddle and the second paddle are prevented from rotating inward.

2. The rapid-entry shoe of claim 1, further comprising an aperture disposed in the heel piece, wherein the engagement between the aperture and an enlarged portion of the deformable element allows rotation of at least one of the first paddle and the second paddle in a first direction, and prevents rotation of at least one of the first paddle and the second paddle in a second direction.

3. The rapid-entry shoe of claim 1, wherein at least one of the first deformable element and the second deformable element prevents inward folding of a topline of the shoe.

4. The rapid-entry shoe of claim 1, wherein the first deformable element and the second deformable element have a second radius of curvature in the uncollapsed configuration that is greater than a first radius of curvature in the collapsed configuration.

5. The rapid-entry shoe of claim 1, wherein the first deformable element and the second deformable element are configured to follow natural contours of a user'"'"'s foot/heel in both the uncollapsed configuration and the collapsed configuration.

6. The rapid-entry shoe of claim 1, wherein a first side of the first deformable element has a first curvature that is different than a second curvature of a second side of the first deformable element.

7. The rapid-entry shoe of claim 1, wherein engagement between the first deformable element and the first anchor is non-pivoting and engagement between the second deformable element and the second anchor is non-pivoting.

8. The rapid-entry shoe of claim 7, wherein the engagement between the first deformable element and the first anchor is free of play and engagement between the second deformable element and the second anchor is free of play.

9. The rapid-entry shoe of claim 1, wherein the first deformable element is coupled to the first anchor and the first anchor is coupled to an anchor receptacle.

10. The rapid-entry shoe of claim 1, wherein the first deformable element comprises a cover that affects flexure of the first deformable element.

11. The rapid-entry shoe of claim 1, wherein in response to moving from the uncollapsed configuration to the collapsed configuration, an opening of the shoe expands by at least about 10%.

12. The rapid-entry shoe of claim 1, wherein a middle portion of at least one of the first deformable element and the second deformable element exhibits a return force toward the uncollapsed configuration of between 1 pound-force and 10 pound-force.

13. The rapid-entry shoe of claim 1, wherein a middle portion of at least one of the first deformable element and the second deformable element returns from the collapsed configuration to the uncollapsed configuration in less than about 1 second.

14. The rapid-entry shoe of claim 1, wherein the heel piece includes a ledge configured to facilitate retaining a user'"'"'s heel within the rapid-entry shoe.

15. The rapid-entry shoe of claim 1, wherein inward rotation of the first paddle and the second paddle is prevented by the neck.

16. The rapid-entry shoe of claim 1, further comprising a rapidentry tongue element comprising one or more of a tongue flare, a cross element or a tongue stiffener.

17. The rapid-entry shoe of claim 1, further comprising a material stiffener configured to direct collapse of a more flexible heel material.

18. The rapid-entry shoe of claim 1, wherein the first anchor and the second anchor are housed within a base which in turn comprises one or more of an outsole, a midsole, an insole or a wedge.
