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.

providing first and second connectors on the vamp at respective medial and lateral sides of the vamp adjacent a rear margin of the vamp;

providing a holder supported on the vamp along at least one of the medial and lateral sides thereof;

connecting the first and second end sections to the first and second connectors, respectively, thereby configuring the sandal in the heel-strap configuration;

detaching at least one of the first and second end sections from the corresponding connector to which it is connected; and

detachably connecting the strap to the holder in the slide configuration.

15. The method of claim 14, wherein:

the strap includes a main portion extending between the first and second end sections;

the connectors include elongated eyelets sized for threading the first and second end sections of the strap therethrough; and

the step of connecting the first and second end sections to the first and second connectors includes threading the first and second end sections through the eyelets, folding back the first and second end sections over the main portion of the strap, and securing the first and second end sections to the main portion of the strap to thereby secure the strap to the vamp.

16. The method of claim 14, further comprising detachably connecting one of the first and second end sections to a second sandal or another article.

17. The method of claim 14, further comprising adjusting the vamp to fit the wearer'"'"'s foot.
