Abstract
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.
Claims14
A rapid-entry shoe comprising:
- a base;
- and
- a heel portion comprising a compressible lattice structure,
- wherein the compressible lattice structure is comprised of a plurality of intersecting ribs,
- wherein the plurality of intersecting ribs defines a plurality of apertures,
- wherein the compressible lattice structure has an open position in which an opening of the rapid-entry shoe is expanded to facilitate reception of a foot of an individual donning the rapid-entry shoe, and
- wherein the compressible lattice structure has a closed position in which the opening is unexpanded to retain the foot within the rapid-entry shoe;
- wherein an upper of the rapid-entry shoe comprises a recess bounded by a step within which to receive the compressible lattice structure such that the intersection between an outer surface of the compressible lattice structure and the upper of the rapid-entry shoe is substantially flush;
- wherein in the open position the compressible lattice structure is compressed downward toward the base of the rapid-entry shoe such that at least a portion of the plurality of apertures are collapsed;
- wherein in the closed position the compressible lattice structure is expanded such that at least a portion of the plurality of apertures are un-collapsed;
- and
- wherein the compressible lattice structure biases the rapid-entry shoe toward the closed position.
