The present disclosure comprises a footbed or sole portion having surface features that is configured to be flipped over or switched with that of an opposite shoe to differently engage with an adjacent surface and thereby adjust a shoe between smaller and larger dimension orientations.

A rapid-entry shoe having a heel counter to prevent inward deflection of a rear portion of the upper, but the heel counter having a vertical slit to permit downward deflection of the rear portion of the upper, so as to expand a perimeter of an opening of the shoe to receive a foot and thereby facilitate donning and doffing of the rapid-entry shoe.

A rapid-entry shoe having an elastic element to enlarge a foot opening of the rapid-entry shoe and also having a stabilizer to prevent a rear portion of the rapid-entry shoe from collapsing downward.

A rapid-entry shoe having a heel arm configured to transition between a collapsed configuration, for easy donning and doffing of the shoe, and an uncollapsed configuration, for securing a foot inside the shoe, the shoe having a resilient member configured to bias the heel arm toward the uncollapsed configuration.

Example embodiments of the present disclosure comprise adjustable footwear having sole structure with interdependent parts. The sole structure may comprise multiple parts and/or portions that are configured such that relative movement between the multiple parts/portions and/or relative material properties of the multiple parts/portions facilitate and accommodate size adjustability of the sole structure (e.g., adjustability in length and/or width). In various embodiments, the interdependent portions of the sole structure may allow for adjustment in one or multiple directions in response to an action (e.g., a single action) taken by a user.

A rapid-entry shoe with a sole portion and a footbed that slide, pivot or translate relative to each other to provide both an open configuration (for ease of donning or doffing by a foot) and a closed configuration (for securement of a foot).

A motion-assist shoe having a force translator with a dynamic portion comprised of a resiliently deformable material and configured to bias a rearward portion of a sole portion of the shoe upward relative to a forward portion of the sole portion.

A rapid-entry shoe having a rotating rear portion configured to be rotated around an axis of rotation and deflected at a fulcrum to create a stress in the rotating rear portion when the shoe is in a collapsed configuration to bias the shoe toward an uncollapsed configuration.

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.
