Although not generally painful, hard, rough skin can be unsightly and irritating if left untreated, it can lead to calluses forming, which can be more stubborn to remove and painful.
The foot withstands far greater pressure than any other part of the body. To compensate, the skin on the sole of the foot is 3 to 4 times thicker and provides a waterproof covering. It is this unique quality that causes the feet to dry out quickly. Basic footcare will maintain the skins balance, but if hard skin is allowed to build up calluses may develop. Most frequent areas are on top and outer edges of the toes, the ball of the foot and back of the heel.
