Why do corns and calluses form on the heels and balls of the feet?
Corns and calluses develop on the heels and balls of the feet primarily due to repeated friction and pressure. This can occur from activities like walking or running, especially if shoes do not fit properly. The skin thickens as a protective response to this irritation.
Key points:
- Friction from ill-fitting shoes can lead to skin thickening.
- High-pressure areas on the foot are more prone to corns and calluses.
- Repeated activities, like sports, increase the risk of development.
- Certain foot shapes can contribute to uneven pressure distribution.
