a shoe for use by a person having paralysis or other restriction of mobility of one foot allows the foot to roll during physiotherapeutic training to gain walking ability . the upper body is used to at least partially support the person on an appropriate aid device during a step taken by the other foot having retained mobility . the shoe worn on the foot of restricted mobility has at least one omnidirectional roller member at the bottom thereof to allow the foot to roll forward to a position where a subsequent step can be taken . the relatively low level of friction involved in initializing the rolling motion of the foot reduces or eliminates reliance on another person to help move the foot forward during physical therapy .
