Abstract
Footwear includes one or more of: (a) an upper portion at least partially defining a foot-receiving chamber; (b) a track component integrally formed or engaged with the upper portion; (c) a heel engaging component movable with respect to the upper portion via the track component between a closed configuration and an open configuration; (d) a locking system, e.g., holding the heel engaging component in the closed configuration; (e) a biasing system, e.g., applying force to the heel engaging component toward the open configuration; (f) a stop system, e.g., keeping the heel engaging component from completely disengaging from the track component; and/or (g) a sole structure. When the footwear is supported upright on a horizontal surface, the heel engaging component may move rearward (and in some examples upward) via the track component when changing from the closed to the open configuration.
