ABSTRACT:
The shoe incorporates adjustable straps that are positioned to tighten the shoe casing around a wearer's instep. A retractor mechanism incorporates elastic members. The elastic members are charged when the wearer loosens shoe by pulling on the straps. The stored energy is released when a catch is released releasing the elastic members to tighten and cinch the shoe on the wearer's foot. During charging a first elastic member is extended an intermediate distance and a second elastic member is charged a greater distance. The second elastic member triggers the release of the first elastic member when it reaches the intermediate position, increasing the tension available for cinching the straps.
