A bladder for an article of footwear includes a chamber having (i) an arcuate segment extending from a first transition to a second transition, (ii) a first plurality of elongate segments extending in a first direction from the first transition to a first terminal end, and (iii) a second plurality of elongate segments spaced apart from the first plurality of elongate segments and extending in the first direction from the second transition to a second terminal end. The bladder also includes a web area connecting the arcuate segment, the first plurality of elongate segments, and the second plurality of elongate segments and extending to a terminal edge spaced apart from each of the first terminal end and the second terminal end.

A bimodal heel counter apt for a rapid entry and release footwear devices, that includes a flexible hollow hemisphere portion, a heel tab, a secondary heel tab, a back sole base, an anchor system, and dependent fastening elements. The bimodal heel counter and dependent fastening systems are biased to one of two stable positions, which elastically morphs by stored potential energy with applied force from one position to the other, configured to collectively snap a footwear device between an open and closed position, for donning and doffing, or securing the foot as to enable active footwear use.

In a sole structure, a first projection can be deformed more easily toward a heel than tiptoe in a through hole of a sole component, due to a heel side gap which is formed between an inclined surface of the first projection and a wall of the first through hole located closer to the heel.

Disclosed is a shoe having a compressible lattice structure in a heel portion to facilitate rapid, easy donning and doffing of shoes. In example embodiments, the lattice structure includes a plurality of interconnected, overlapping, intersecting and/or woven ribs defining a plurality of apertures. The lattice structure has an open position in which the shoe opening is expanded to facilitate reception of a foot of an individual wearing the rapid-entry shoe, and a closed position in which the shoe opening is smaller to retain the foot within the rapid-entry shoe.

A bimodal shoe having a bimodal structure, the bimodal structure configured to selectively snap to at least one of a second position and a first position. The bimodal structure is a bendable structure that selectively snaps into the first position upon being subjected to a first bending force, and that selectively snaps into the second position upon being subjected to a second bending force, where the first bending force has an opposite direction to the second bending force. A downward force applied to a heel counter of the bimodal shoe while holding portions of the shoe forward from the bimodal structure stationary causes the bimodal structure to snap out of the second position.

A support is configured such that a bulge is allowed to deform toward a deformation space due to the deformation space when the deformation space is in an open state, and that the bulge is allowed to deform upward and a buffer member is compressively deformed when the deformation space is in a closed state.
