Calluses and corns are areas of thick skin caused by pressure or friction. They may cause pain when a person walks or wears shoes.
Corns have an inner core that can be soft or hard. Soft corns are found between toes. Hard corns may form on the top of a toe. Corns caused by poorly fitting shoes will often go away with the right size shoe. Using protective padding to cushion the corn can help relieve pain while the toe heals.
