What Are Corns & Calluses?

Corns and calluses are thickened areas of skin that form in response to friction or pressure. Corns are small, round growths that typically form on the toes, while calluses are larger and usually develop on the soles of the feet. Both conditions can be the result of ill-fitting shoes or incorrect alignment of the bones in the feet. Corns and calluses are often accompany other foot problems such as bunions, hammertoes, and blisters. Both corns and calluses are benign conditions that usually require no treatment. However, if they cause pain or make it difficult to walk, you may need to see a podiatrist for treatment.
