Abstract:
A device configured to surround a portion of a foot-receiving cavity at a heel region of an article of footwear includes a control bar having a center segment, a medial side arm extending from the center segment, and a lateral side arm spaced from the medial side arm and extending from the center segment. The device may include an extension extending toward the control bar. At least a portion of the control bar may be elastically deformable under an applied force depressing the control bar toward the extension, and the extension may limit movement of the control bar. The control bar may be adapted to return to an unloaded position upon removal of the applied force.
