Corns and Calluses on Feet: Common Causes, Skin Response, and When to Be Concerned
Corns and calluses are common foot conditions that develop when the skin is repeatedly exposed to pressure or friction. While often uncomfortable, they are generally not considered dangerous and are usually the body’s natural response to protect itself.
These thickened areas of skin typically form due to footwear issues, such as shoes that are too tight, too loose, or high-heeled. Wearing second-hand shoes can also contribute, as they may already be molded to another person’s foot shape, creating uneven pressure points that do not align with the wearer’s natural foot structure.
Over time, the skin reacts by building up layers of hardened tissue composed mainly of keratin. This process is a protective mechanism designed to reduce further damage in high-friction areas.
Corns, a specific type of callus, often develop on the tops or sides of toes. They may contain a central core and can cause discomfort, sometimes described as a sensation similar to a small object pressing into the skin while walking.
Health professionals note that while most cases can be managed with proper footwear and foot care, persistent pain, changes in appearance, or difficulty walking may warrant medical evaluation to rule out underlying issues or prevent complications.
