Rapid-entry footwear having an expandable opening
Footwear is disclosed herein that comprises a base with a cut-out and/or a fold pattern, either of which, when actuated, is useful to transform the footwear from a closed/relaxed configuration to an open/actuated configuration in which the rapid-entry shoe has an expanded shoe opening to facilitate reception of a foot of an individual wearing the rapid-entry shoe.
1. A rapid-entry shoe comprising:
a base having a forward portion, a rearward portion, a medial side, and a lateral side; and
a waist extending between the medial side and the lateral side of the base, the waist located at the intersection of the forward portion from the rearward portion, the waist comprising a fold pattern in the base, and the fold pattern having a plurality of non-parallel folds;
wherein the rapid-entry shoe has a relaxed configuration in which the forward portion and the rearward portion are substantially coplanar around the waist;
wherein application of opposing inward forces substantially colinear with at least one fold of the plurality of folds the waist results in the rapid-entry shoe assuming an actuated configuration in which the rearward portion and the forward portion are folded around, or angled relative to, the waist; and
wherein an opening of the rapid-entry shoe is larger in the actuated configuration than in the relaxed configuration.
2. The rapid-entry shoe of claim 1 , wherein the waist comprises a tread feature in the base of the rapid-entry shoe.
3. The rapid-entry shoe of claim 1 , wherein the rapid-entry shoe is biased toward the relaxed configuration.
4. The rapid-entry shoe of claim 1 , wherein the resilient member is attached to the upper of the shoe.
5. The rapid-entry shoe of claim 1 , wherein a resilient member is attached to the base of the rapid-entry shoe, the resilient member configured to bias the rapid-entry shoe toward the relaxed configuration.
6. A rapid-entry shoe comprising:
a base having a forward portion, a rearward portion, a medial side, and a lateral side; and
a waist extending between the medial side and the lateral side of the base, the waist located at the intersection of the forward portion from the rearward portion, the waist comprising a fold pattern in the base, and the fold pattern having a plurality of folds;
wherein the rapid-entry shoe has a relaxed configuration in which the forward portion and the rearward portion are substantially coplanar around the waist;
wherein the plurality of folds form opposing triangles, one with its base on the medial side, one with its base on the lateral side, wherein the fold pattern further comprises a bisecting fold intersecting the opposing triangles;
wherein application of opposing inward forces on the bases of the opposing triangles actuates the bisecting fold and results in the rapid-entry shoe assuming an actuated configuration in which the rearward portion and the forward portion are folded around, or angled relative to, the waist; and
wherein an opening of the rapid-entry shoe is larger in the actuated configuration than in the relaxed configuration.
7. A rapid-entry shoe comprising:
a base having a forward portion, a rearward portion, a medial side, and a lateral side; and
a waist extending between the medial side and the lateral side of the base, the waist located at the intersection of the forward portion from the rearward portion, the waist comprising a fold pattern in the base, and the fold pattern having a plurality of folds;
wherein the rapid-entry shoe has a relaxed configuration in which the forward portion and the rearward portion are substantially coplanar around the waist;
wherein the plurality of folds form opposing trapezoids, one with its base on the medial side, one with its base on the lateral side, wherein the fold pattern further comprises two bisecting folds intersecting the opposing trapezoids;
wherein application of opposing inward forces on the bases of the opposing trapezoids actuates the two bisecting folds and results in the rapid-entry shoe assuming an actuated configuration in which the rearward portion and the forward portion are folded around, or angled relative to, the waist; and
wherein an opening of the rapid-entry shoe is larger in the actuated configuration than in the relaxed configuration.
