What Are Calluses?

Like corns, a callus happens when there’s a buildup of hard, dead skin over an area of pressure or a place where your foot is bony.

Calluses may be painful or merely unsightly, but you know you have one when you notice a large area of thickened skin, especially on the heel, ball of foot, or sides of the foot.

What Causes Calluses?

Your outer layer of skin has special skin cells called keratinocytes, which produce calluses. It’s your body’s way of helping to lessen friction or pressure – often on the heel, ball of foot, and the sides of your feet. The friction or pressure could be from your shoes, sports, daily activity or merely from a unique characteristic in the way you walk.
