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.

First claim

What is claimed is:

1. A rapid-entry shoe comprising:
a sole having an upper surface configured to support a user's foot;
a rear portion comprised of a flexible upper material and configured to secure the user's foot in the rapid-entry shoe on the upper surface of the sole; and
a heel structure comprising a resilient arc portion and a base portion;
wherein the resilient arc portion extends from a side of the rear portion, around the rear portion, and to an opposing side of the rear portion of the rapid-entry shoe, a rearmost portion of the resilient arc portion comprising a heel piece having a cross section configured to direct the user's foot into the rapid-entry shoe;
wherein the base portion is coupled to the sole and extends below the resilient arc portion from the side of the rear portion, around the rear portion, and to the opposing side of the rear portion of the rapid-entry shoe;
wherein the resilient arc portion and the base portion combine to form a closed perimeter and define an opening between the base portion and the resilient arc portion, the opening being open to the rear portion;
wherein the flexible upper material of the rear portion is coupled to the resilient arc portion at the heel piece;
wherein the resilient arc portion of the heel structure is positioned external to an outer surface of the flexible upper material such that the resilient arc portion can move relative to an adjacent surface of the flexible upper material; and
wherein the resilient arc portion is configured to have a native position in which the resilient arc portion holds the rear portion of the rapid-entry shoe in a closed position securing the user's foot in the rapid-entry shoe and wherein the resilient arc portion is configured to be deformed by an opening force to open the rapid-entry shoe to permit rapid entry of the user's foot into the rapid-entry shoe.

2. The rapid-entry shoe of claim 1 , wherein a split between the resilient arc portion and the adjacent surface of the flexible upper material of the rear portion is configured to widen in response to heel compression without drawing lateral and medial rear quarters of the rear portion of the rapid-entry shoe inward.

3. The rapid-entry shoe of claim 1 , wherein the heel piece comprises differing layers of material between which are coupled the flexible upper material of the rear portion.

4. The rapid-entry shoe of claim 1 , wherein the resilient arc portion is non-rotatably coupled to the sole and exhibits a dynamic arc of curvature exclusively above the sole.

5. A rapid-entry shoe comprising:
a sole having an upper surface configured to support a user's foot;
a rear portion comprised of a flexible upper material and configured to secure the user's foot in the rapid-entry shoe on the upper surface of the sole; and
a heel structure comprising a deformable curve portion and a base;
wherein the deformable curve portion extends from a side of the rear portion, around the rear portion, and to an opposing side of the rear portion of the rapid-entry shoe, an uppermost and rearmost portion of the deformable curve portion comprising a heel piece shaped to direct the user's foot into the rapid-entry shoe;
wherein the base is coupled to the sole and extends below the deformable curve portion and from the side of the rear portion continuously to the opposing side of the rear portion of the rapid-entry shoe;
wherein the deformable curve portion and the base combine to form a closed perimeter and define an opening between the base and the deformable curve portion;
wherein the deformable curve portion of the heel structure is positioned external to an outer surface of the flexible upper material such that the deformable curve portion can move relative to an adjacent surface of the flexible upper material; and
wherein the deformable curve portion is configured to have a native position in which the deformable curve portion holds the rear portion of the rapid-entry shoe in a closed position securing the user's foot in the rapid-entry shoe and wherein the deformable curve portion is configured to be deformed by an opening force to open the rapid-entry shoe to permit rapid entry of the user's foot into the rapid-entry shoe.

6. The rapid-entry shoe of claim 5 , wherein a split between the deformable curve portion and the adjacent surface of the flexible upper material of the rear portion is configured to widen in response to heel compression without drawing lateral and medial rear quarters of the rear portion of the rapid-entry shoe inward.

7. The rapid-entry shoe of claim 5 , wherein the deformable curve portion is non-rotatably coupled to the sole and exhibits a dynamic arc of curvature exclusively above the sole.

8. A rapid-entry shoe comprising:
a sole having an upper surface configured to support a user's foot;
a flexible upper material forming a rear portion of the rapid-entry shoe and configured to secure the user's foot in the rapid-entry shoe on the upper surface of the sole; and
a rebounding heel structure comprising a base and a deformable element, wherein the deformable element is configured to have a native position in which the deformable element holds the rear portion of the rapid-entry shoe in a closed position securing the user's foot in the rapid-entry shoe and wherein the deformable element is configured to be deformed by an opening force to open the rapid-entry shoe to permit rapid entry of the user's foot into the rapid-entry shoe;
wherein the deformable element of the rebounding heel structure extends upward and rearward from a forward portion of the base and extends around the rear portion of the rapid-entry shoe above the sole;
wherein the base of the rebounding heel structure extends substantially horizontally around a periphery of the rear portion of the rapid-entry shoe and is positioned below the deformable element;
wherein the deformable element and the base combine to form a closed perimeter and define an opening between the base and the deformable element, the opening being open to the rear portion of the flexible upper material; and
wherein the deformable element of the rebounding heel structure is positioned external to an outer surface of the flexible upper material.

9. The rapid-entry shoe of claim 8 , wherein the base is configured to direct collapse of the flexible upper material in response to heel compression from the opening force.

10. The rapid-entry shoe of claim 8 , wherein the deformable element is non-rotatably coupled to the sole and exhibits a dynamic arc of curvature exclusively above the sole.

11. The rapid-entry shoe of claim 1 , wherein a first section of the resilient arc portion has a first cross section and a second section of the resilient arc portion has a second cross section that is different in thickness or shape from the first cross section to provide the resilient arc portion with a directional bias.

12. The rapid-entry shoe of claim 5 , wherein a first section of the deformable curve portion has a first cross section and a second section of the deformable curve portion has a second cross section that is different in thickness or shape from the first cross section to provide the deformable curve portion with a directional bias.

13. The rapid-entry shoe of claim 5 , wherein the heel piece comprises differing layers of material between which are coupled the flexible upper material of the rear portion.

14. The rapid-entry shoe of claim 8 , wherein the deformable element of the rebounding heel structure and the base of the rebounding heel structure are a unitary structure.

15. The rapid-entry shoe of claim 8 , wherein
