While corns can be found on the bottom of the foot where pressure is usually applied, it is more common that you find corns on the tops and sides of your toes and even between your toes. When pressure is applied, corns can cause significant pain and discomfort.
Calluses, on the other hand, don’t usually cause pain. They usually develop on the soles of your feet, especially under the heels or balls, on your palms, or on your knees. Calluses vary in size and shape and are often larger than corns.
Be cautious about wearing ill-fitting shoes, not wearing socks with shoes, and constantly playing instruments or using your hands as these things can increase the risk for corns and calluses.
