Wearing sandals, going barefoot, jogging or doing other impact exercise, the aging process, and genetics all play a role in how rough your feet are. Rough, thick feet skin will snag fabric, can hurt, and is at risk for cracks that can become infected. Everyone over the age of 20 will get rough feet from time to time unless they have a method of controlling the thickness of foot skin.
If the skin on your feet is just a little thick and rough then simply filing your feet in the bath or shower with this professional foot file will help you keep them soft and prevent cracking and roughness. If your foot skin is really thick though, you'll need the products in my Soft and Smooth Feet Kit to control skin thickness and prevent cracking.
