Abstract: A foldable sandal includes a forefoot portion that is adapted to be disposed under a front portion of a wearer's foot, a rear-foot portion that is adapted to be disposed under a rear portion of the wearer's foot, and a folding member outsole that functions as the folding member and the bottom layer of the sandal. The folding member is operatively coupled to both the forefoot portion and the rear-foot portion wherein the folding member is adapted to enable the foldable sandal to be selectively moved between an open configuration suitable for wearing and a folded configuration suitable for storage. The sandal may also have a retaining member fastened to the folding member outsole or the forefoot portion and/or the rear-foot portion to hold the sandal on the wearer's foot.
