Does a corn grow from a seed?
Many corns occur regardless of how "good" a shoe is. A bone in the toe is often causing pressure internally. This could be from arthritis, bone spurs, or a contracture of the joint known as a hammertoe. The pressure from the bone also forms the conical area of hard, dead skin called a corn. Treatment for this includes padding and wearing shoes with more room inside. Surgery to remove the pressure from the bone is often the best definitive treatment for a persistent corn.
