Abstract

A rapid-entry shoe allows the shoe to be rapidly entered and readied for wearing by the user. The shoe may be any of a wide variety of shoe types, including shoes of a wide variety of styles and functions. The rapid entry features of the shoes utilize various movable elements that are attached to a sole portion or other portion of the shoe and allow movement of a portion of the shoe under pressure to allow rapid entry of the user's foot into the shoe. The moveable elements may include flexible elements, elements having constructed to have a memory of a native position, magnetic elements, and/or elastic elements.

First claim

The invention claimed is:

1. A rapid-entry shoe comprising:
a sole having an upper surface configured to support a user's foot;
an upper attached to the sole and configured to surround and secure the user's foot on the sole;
a rear portion configured to secure the user's foot in the shoe on the upper surface of the sole; and
a deformable element coupled to the sole and the rear portion, wherein the deformable element is configured to have a native position in which the deformable element holds the rear portion of the shoe in a closed position securing the user's foot in the shoe and wherein the deformable element may be deformed by an opening force to open the shoe to permit rapid entry of the user's foot into the shoe,
wherein the deformable element comprises a loop portion and opposing sides extending from the loop portion downward toward the sole, wherein each side of the deformable element comprises a bendable portion, wherein the bendable portion of each side of the deformable element is configured to flex and bend above the upper surface of the sole in response to the opening force,
wherein the bendable portion comprises a flexible location in the deformable element on each side of the deformable element, the flexible location defining an axis of rotation in the deformable element, the axis of rotation being located above the upper surface of the sole, and
wherein the deformable element comprises an axial twist at the bendable portion of each side of the deformable element.

2. A rapid-entry shoe as recited in claim 1 , wherein each bendable portion comprises a hinged connection.

3. A rapid-entry shoe as recited in claim 2 , wherein the deformable element comprises a spring biasing the deformable element to the native position.

4. A rapid-entry shoe as recited in claim 1 , wherein the loop portion extends around the rear portion and is connected to the sole, anterior the rear portion.

5. A rapid-entry shoe as recited in claim 1 , wherein the deformable element is covered by shoe cushioning components.

6. A rapid-entry shoe as recited in claim 1 , wherein the axial twist is configured to facilitate flexing and bending at the bendable portion of each side of the deformable element so as to allow the loop portion to move upward and downward.
