As the wearer takes a step, the device pushes the nonparetic foot backward during stance. This exaggeration of the step length asymmetry is hypothesized to result in a more symmetric gait pattern once the shoe is removed. In addition, the shoe works to strengthen the paretic leg by slightly destabilizing the nonparetic leg, which encourages the wearer to use their paretic leg more. A flexible height and weight matched platform worn on the paretic foot equalizes the added height and weight of the device
