  • Retractable foot gear for disabled persons
    Patent number: 6905127
    Abstract: The retractable foot gear 10 includes a sole 12 and a retractable wheel, ball, blade, or similar low friction element 16 which normally projects from a recess formed into the shoe's sole 12. The low friction element 16 retracts into a recess 14 when a predetermined amount of force is exerted on the low friction element 16. The low friction element 16 is additionally biased so as to automatically return to an extended position when the predetermined force is relieved. The retractable foot gear 10 assists persons with difficulty in walking, standing, or maneuvering. Moreover, the protruding low friction element enables one to slide one foot along a walking surface while minimizing the tendency of one to slip and fall.
