Abstract

The pivotable footwear including a front portion, a heel portion, a flexible sole defining a channel extending across the flexible sole, a shoe upper attached to the flexible sole, and a lockable hinge mechanism disposed within the channel. The lockable hinge has an unlocked position wherein the heel portion of said footwear is free to pivot about the channel relative to the front portion of the footwear, and a locked position wherein the heel portion of the footwear is locked into position relative to the front portion of said footwear. The lockable hinge mechanism is electronically actuated and battery operated and controlled to move between the locked position and the unlocked position by actuation of an electronic remote control. That is, actuation of the electronic remote control causes the hinge to move the footwear to an open, foot insertion position and a wearable locked position.
