Massage your feet gently with this scrub and concentrate on tough areas of feet and sore spots for about 2 minutes for each foot. Next I like to use a pumice stone especially used all over India for pedicure, it is made of terracotta and has little holes in it that make it extra effective but is the best thing I have ever used on feet and gets rid of callouses or rough spots super fast. This tool becomes ultra effective when soaked in warm or hot water for 5 minutes.
