A device configured to surround a portion of a foot-receiving cavity at a heel region of an article of footwear comprises a control bar having a center segment, a first side arm extending from the center segment, and a second side arm spaced from the first side arm and extending from the center segment. The control bar may include a series of slats. A base supports the control bar and is connected to the first side arm and the second side arm. The control bar is biased to an unstressed position with the center segment a first distance from the base, and elastically bends under an applied force to a loaded position with the center segment a second distance from the base less than the first distance. The device stores potential energy that returns the control bar to the unloaded position upon removal of the applied load.

A dual-hardness outsole includes a front section, a middle section, and a rear section, at least the middle section of the outsole including a wedge having a bottom surface which extends below another bottom surface of at least one of the front and rear sections such that the wedge carries more weight than the other bottom surface. The outsole comprises a hard portion and a soft portion that are secured to each other and together form the wedge, a cross-sectional profile of the hard and soft density portions being such that a center portion of the wedge is softer than opposite lateral portions thereof.

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.

Safety footwear configured to provide protection to the instep region and/or metatarsals of a wearer. The footwear includes a metatarsal guard having a rigid central spine, multiple ridge elements that extend transversely to the spine across an instep of the footwear, and a cushion element joined with the central spine that extends outward under the multiple ridge elements. The ridge elements are raised to deflect impact forces imparted on the metatarsal guard and the cushion element provides enhanced cushioning to a foot of a wearer of the footwear. With these constructions, the footwear remains flexible enough to provide enhanced mobility to a wearer.

A system and method for footwear with a handless entry construction. A heel band may be provided in the footwear that is sufficiently deformable and sufficiently resilient to handlessly a) facilitate insertion of a wearer's foot into the footwear and b) move upward relative to a ground surface to engage a heel of the wearer's foot in order to aid in securing the wearer's foot within the footwear.

A microcellular shoe stiffener has at least one adhesive layer coextruded with and carried on a stiffener core. A liquid, such as liquid nitrogen, is introduced into the extruder for the stiffener core to produce a closed cell foam with a gaseous component. The gas reduces the weight and cost of the stiffener with out significantly reducing stiffness and resiliency.
