Abstract
Abstract The conventional step-in or slide-on slipper tends to loosen and slide off the front of the foot during normal walking motion. Binding or otherwise tightly clasping the slipper to the foot defeats the general purpose of the slipper as an easily attired article of footwear. This invention is an article adapted to be rapidly assembled into a slipper of the step-in or slide-on type that remains comfortably loose during wearing and is adapted to remain secured to the foot during walking or other foot movement.
