Full Answer

Corns most often develop on the top of the toes; however, growths referred to as soft corns can also form between the toes, explains PodiatryNetwork.com. When corns form on top of the toes, they are often due to a foot condition that causes the toes to press against the top of the shoe. Abnormal foot bone structure typically causes soft corns, which most often form between the fourth and fifth toes.

Treatments for corns include trimming down the excess skin and the application of topical medications, such as salicylic acid, according to Mayo Clinic. Individuals with corns should never attempt to pare down the skin or remove the growths on their own, as this can increase the risk of infection. In certain cases, individuals may need surgery to repair the underlying foot bones. Sufferers may also be able to prevent new corns from developing by wearing comfortable shoes and utilizing orthotic shoe inserts to minimize foot pressure.
