Problems solved by technology

In some of these shoes, the heel straps are disconnected from the shoes when converting to the slide configuration and must thereafter be stored separately or carried by the wearer (e.g., in the wearer's pocket), subjecting the heel straps to being misplaced or lost.
The pivot mechanisms increase the complexity of the sandal construction and are subject to mechanical failure.

Abstract

A convertible sandal comprises a vamp extending over a forefoot portion of the wearer's foot and first and second connectors located along respective medial and lateral sides of the vamp adjacent a rear margin of the vamp. A strap is secured to the connectors and movable selectively between a first position, in which the strap extends behind a heel of the wearer's foot, and a second position, in which the strap extends over the wearer's forefoot. The connectors may include elongated eyelets through which first and second end sections of the strap are threaded and then folded back against the strap for securing the strap to the connectors. In some embodiments a holder is provided for securing the straps across the forefoot or for connecting the sandal to a second sandal or another item using the strap.
