An expandable shoe includes an outer shell and an adjustable inner assembly within the outer shoe. The inner assembly includes a first sole portion, a second sole portion, and a screw drive. The screw drive has a screw passing through a screw insert mounted to one of the first and second sole portions and a screw-receiving portion attached to the other of the first and second sole portions, so that turning the screw causes the sole portions to move relative to one another, thereby adjusting a dimension of the shoe. The shoe includes a manually operable control to turn the screw without the need for tools. The control is operable between a first position in which the control resists movement around an axis defined by the screw and a second position in which the control can be used to turn the screw to adjust a dimension of the footwear.
