Abstract
The footwear can be convertible between a shoe configuration and a sandal configuration. A flexible front vamp portion can be elevated into an upwardly flexed and elevated position so it creates a cavity, in conjunction with the footwear upper portion, to receive the foot of the wearer to provide a shoe configuration. In particular, the toes of the wearer can reside in the cavity portion formed by the flexible front vamp portion. For conversion to a sandal configuration, the midsole can be removed from the outer sole and the front vamp portion can be downwardly flexed so that it collapses and then nests into the outer sole. The midsole can be replaced back into the outer sole, with the front vamp portion captured between the midsole and the outer sole, so the footwear can function as a sandal with the wearer's toes exposed.
