PROBLEM TO BE SOLVED: To provide a toe stimulating ball for preventing stumbling, which heightens aged persons' wills to walk and their interests in walking by stimulating their feet, as a method for encouraging them to walk for the purpose of retaining their health. SOLUTION: Each of the linked stimulating balls (made of elastic rubber) is inserted for fixation between respective adjacent two of the aged person's toes and used for walking. The stimulating balls give a moderate stimulus to his or her foot, reduce his or her stumbling, and promote his or her health.
