Baby Foot is simple! Apply the sock packs to your feet, they'll fit up to a men's size 13. Leave the packs on your feet for 1 hour then gently wash with soap and cool to warm water. In 5-7 days you'll begin to experience peeling as the outer layers of dead skin release from your feet. Use Baby Foot every one to two months. If you have active foot fungus some stinging may occur. Do not use Baby Foot if you have open sores or cuts on your feet.
