Once you can easily do the Foot Waker routines, graduate to Foot Savers. These plastic half-spheres, smaller and harder than Foot Wakers, are an intense, powerful tool for improving foot function and preventing your feet from restricting you at any time of life. Foot Savers actually re-educate feet. They improve gait, alignment, and muscle tone, stimulate reflexology points, strengthen arches, increase range of motion, and stimulate and elongate the muscles of the calves, thighs, hips, and lower back.
