The condition may clear up without any attention, but it usually requires treatment. An untreated fungal infection can lead to bacteria-inviting cracks in the skin. The affected area should be kept dry, clad in dry cotton socks or sandals, or kept uncovered. A number of nonprescription fungicide sprays will cure athlete's foot, including: clotrimazole (Lotrimin), ketoconazole (Nizoral), miconazole-nitrate (Monistatderm), sulconazole (Exelderm), or tolnaftate (Tenactin). Before applying, the feet should be bathed well with soap and water, and then well dried (especially between the toes). The sprays should be applied to all sides of the feet twice a day for up to four weeks. After the spray has been applied, the feet should be covered in clean, white cotton socks. For cases that do not respond to the sprays, a physician may prescribe an oral medicine (griseofulvin) or Ketoconazole.

When the acute phase of the infection passes, the dead skin should be removed with a bristle brush in order to destroy the living fungi. All bits of the skin should be washed away.
