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 and a second paddle, wherein the heel piece is located at a rear portion of the rapid-entry shoe;

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

a first deformable element coupled directly to the first anchor and extending between the first anchor and the first paddle; and

a second deformable element coupled directly to the second anchor and extending between the second anchor and the second paddle;

wherein the shoe comprises a collapsed configuration and an uncollapsed configuration;

wherein in the collapsed configuration the first deformable element and the second deformable element are in a compressed state; and

wherein in the uncollapsed configuration the first deformable element and the second deformable element are oriented upwards and are in a partially compressed state.

2. The rapid-entry shoe of claim 1, wherein the first deformable element is partially compressed in the uncollapsed configuration.

3. The rapid-entry shoe of claim 1, wherein the first deformable element exhibits a return force toward the uncollapsed configuration of between about 4 pound-force and about 8 pound-force.

4. The rapid-entry shoe of claim 1, wherein the first deformable element returns from the collapsed configuration to the uncollapsed configuration in less than about 0.2 seconds.

5. The rapid-entry shoe of claim 1, wherein an arc of curvature of the first deformable element comprises a first radius of curvature in the collapsed configuration and a second radius of curvature in the uncollapsed configuration, wherein the first radius of curvature is 30% to 60% smaller than the second radius of curvature.

6. A rapid-entry shoe, comprising:

a heel piece comprising a first paddle coupled to a second paddle, wherein the heel piece is located at a rear portion of the rapid-entry shoe, and wherein the first paddle is disposed on a medial side of the rapid-entry shoe and the second paddle is disposed on a lateral side of the rapid-entry shoe;

wherein the shoe comprises a collapsed configuration and an uncollapsed configuration;

wherein in the collapsed configuration the first paddle is rotated downward about a first axis of rotation and outward about a second axis of rotation and the second paddle is rotated downward about the first axis of rotation and outward about a third axis of rotation;

wherein in the uncollapsed configuration the first paddle is rotated upward about the first axis of rotation and inward about the second axis of rotation and the second paddle is rotated upward about the first axis of rotation and inward about the third axis of rotation;

wherein the first axis of rotation extends from the lateral side of the rapid-entry shoe to the medial side of the rapid-entry shoe; and

wherein the second axis of rotation comprises a longitudinal axis of the first paddle and wherein the third axis of rotation comprises a longitudinal axis of the second paddle.
