FOOTWEAR HEEL SPRING DEVICE

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.

Footwear article with doffing ledge

A footwear article includes a doffing ledge that may provide a lever for pressing the footwear article in one direction, while the wearer slides his or her heel out of the footwear article in a different direction. A doffing angle of the doffing ledge is based, at least in part, on a forwardly inclined angle of a center connecting band near a rear portion of the ankle collar.

Upper component for an article of footwear

An upper component for an article of footwear allows easy entry of the foot into the article of footwear. The upper component includes a heel body, which includes a first portion partially defining an ankle opening. The heel body further includes a second portion coupled to the first portion. The second portion is foldable and partially defines the ankle opening. The second portion is movable relative to the first portion between an unfolded configuration and a folded configuration. The upper component includes at least one tension member coupled to the second portion. The tension member is movable relative to the first portion to move the second portion from the unfolded configuration to the folded configuration. The ankle opening is larger when the second portion is in the unfolded configuration than when the second portion is in the folded configuration.
