Ankle strap transformation footwear for slipper and sandal conversion

Abstract

A novel ankle strap transformation footwear capable of transforming from an ankle-strapped sandal mode to an ankle-strapless slipper mode is disclosed. In the ankle-strapped sandal mode, a first ankle strap piece and a second ankle strap piece are bound together to form a combined ankle strap. In the ankle-strapless slipper mode, the first ankle strap piece and the second ankle strap piece are separated, swiveled forward, and then attached to a main cover or a main strap of the novel ankle strap transformation footwear. Preferably, in the ankle-strapped sandal mode, the first ankle strap piece and the second ankle strap piece utilize attachment strips and a belt loop for binding together. In the ankle-strapless slipper mode, the first ankle strap piece and the second ankle strap piece utilize attachment strips to attach to the main cover or the main strap of the novel ankle strap transformation footwear.
