A foot corn is a small, raised, round bump that consists of hardened layers of dead skin. Corns typically form on the tops and sides of the toes, the areas that tend to experience pressure and friction from wearing shoes. However, corns can also form on the soles of the feet in some cases. Corns on the foot are often tender to the touch, and they can be painful when they press against shoes.
There are three different types of corns:
• Hard corns are the most common type of corn. They are hard to the touch and contain a dense center. They typically form on the tops of the toes.
• Soft corns typically form between the toes. Unlike hard corns, soft corns are spongy and pliable. They are often white or gray in color.
• Seed corns tend to be very small. They typically form on the bottoms of the feet, often in groups or clusters.
