A simple, yet powerful foot massage that's easy and fun. Dr. C. Everett Koop extols the benefits of soaking and massaging feet. Sounds crazy, but rolling feet over marbles really works - leaving feet tingly and revitalized after even 5 minutes of massage. You have to try it to believe it! Kit contains a rolling pool, marbles, a shooter marble and a simple foot Reflexology chart. Just inflate the rolling pool, pour in the marbles and gently roll feet over them. Try heating or chilling the marbles first for an unforgettable massage.
