Foot corns are small, hardened areas of skin that develop when the feet experience repeated pressure or rubbing. They often appear on the tops or sides of the toes or on the soles of the feet. While corns may seem minor, they can become quite painful and make walking uncomfortable. Wearing properly fitting shoes with plenty of toe room is one of the best ways to prevent them. Keep your feet clean, moisturized, and inspect them regularly for any changes. Never try to cut or remove a corn yourself, as this can lead to infection. If a corn becomes painful or persists, seek advice from a qualified foot care professional.
