Corns on the feet are small, hardened areas of thickened skin that develop due to repeated pressure or friction. They often form on bony areas, such as the tops or sides of toes, from wearing tight or ill-fitting shoes, walking in high heels, or repeated rubbing. The body creates corns as a protective response to prevent damage to the skin and underlying tissue.
This condition is common, but it is often preventable and treatable. To prevent corns on your feet, wear well-fitting, comfortable shoes with enough room for your toes. Use protective padding or inserts to reduce pressure and friction. If they become problematic or painful, then professional treatment may be required.
