Ergonomic Ergonomic Footrest: The ergonomic design of our foot stretcher ensures the foot is optimally positioned to improve stretching of the leg and foot muscles. In addition, a space in the middle of the foot allows the use of the rocker foot to strengthen the ankles. Non-slip rocker design: Non-slip rubber grips at the bottom of the foot rocker ensure that the stretcher will not slip when used on any type of surface.
