Corns are small areas of thickened skin that often occur in a circular shape, developing on the sole of your foot or the tops of your toes. Calluses are rough areas of the skin that are hard and appear yellow in colour. They have less sensitivity than the surrounding skin, and they can cause pain and discomfort when walking/running.
The main cause of corns and calluses is excessive pressure on the foot, often occurring when your footwear is rubbing. If you are a runner or involved in high levels of activity, corns and calluses can develop with pressure caused during the movement. If you do not treat them they will build up and become more painful.
Choosing the right footwear is beneficial in reducing the risk of corns and calluses. Making sure you dry your feet thoroughly after washing them and regularly applying moisturiser is important to help prevent the formation of calluses and corns. Using a stone or foot file can also help to reduce the build-up of hard skin.
When seeing your podiatrist, they will use a scalpel to remove the corns and calluses. They can also prescribe you with orthotics to release the pressure.
