Corns on feet are thick, hardened layers of skin that develop when the skin tries to protect itself against friction or pressure. The most common cause of corns is shoes that dont fit properly, which can cause repeated friction, rubbing, or irritation and pressure on the skin. Other sources of friction and pressure that can cause corns include:
- Wearing ill-fitting socks
- Wearing high heels or shoes with pointed toes
- Having bunions or hammertoes
- Participating in activities that put pressure on the feet, such as running or dancing
To prevent corns, it is important to wear shoes that fit properly and to avoid activities that put excessive pressure on the feet. If corns do develop, they can often be treated by simply removing the source of the friction or pressure that caused them. This may involve changing shoes, wearing cushioned socks, or using soft insoles or heel pads in shoes.
