An apparatus includes a heel section, a mid-foot section, and a toe section. The heel section, the mid-foot section, and the toe section collectively have a geometric shape having a first slope of a polarity along an inner edge of the apparatus from the toe section to the heel section and a second slope of the polarity along the inner edge of the apparatus to an outer edge of the apparatus at the toe section.

A rapid-entry shoe having an upper, a sole portion, and at least one pocket coupled to a rear portion of the upper and encapsulating a compressed medium that biases a topline of the shoe toward an uncollapsed configuration.

A rapid-entry shoe with a rotating tongue having an open configuration for ease of donning or doffing by a foot and also having a closed configuration for retention of the foot.

A rapid-entry shoe allows the shoe to be rapidly entered and readied for wearing by the user. The shoe may be any of a wide variety of shoe types, including shoes of a wide variety of styles and functions. The rapid entry features of the shoes utilize various movable elements that are attached to a sole portion or other portion of the shoe and allow movement of a portion of the shoe under pressure to allow rapid entry of the user's foot into the shoe. The moveable elements may include flexible elements, elements having constructed to have a memory of a native position, magnetic elements, and/or elastic elements

An article of footwear comprises a sole, and an upper that has a medial side portion extending from the medial side of the sole with a first distal end remote from the medial side. The upper has a lateral side portion extending from the lateral side of the sole with a second distal end remote from the lateral side. The upper may include a support member extending at least partially across the foot-receiving surface with a first end remote from the medial side. The medial and lateral side portions wrap at least partially around a foot with the first distal end securable proximal to the lateral side, and the second distal end separately securable proximal to the medial side. An article of footwear has cables with proximal ends fixed to one side of the upper and that extend through looped cables on an opposite side of the upper.

A self-lacing system includes an air bag assembly and a vacuum pump respectively attached on an upper portion and a sole portion of the shoe. The vacuum pump includes a first cover and a second cover. A chamber is formed between the first cover and the second cover when the second cover is located at the first position relative to the first cover. Volume of the chamber changes during movement of the second cover relative to the first cover. During the movement of the second cover relative to the first cover, the vacuum pump drives fluid inside the air bag assembly to flow into the chamber via a suction communication channel to collapse an air passage on the air bag assembly for shrinking and reshaping the air bag assembly, which drives the upper portion of the shoe to shrink and reshape for tightening the shoe.
