Symptoms of tinea pedis include a build up of scale on the feet and sometimes redness and itching.
Doctors base the diagnosis on an examination of the feet.
Treatment includes antifungal drugs applied directly to the affected areas or occasionally taken by mouth and measures to keep the feet dry.

Symptoms of Athlete's Foot
The fungus can cause mild scaling with or without redness and itching. The scaling may involve a small area (particularly between the toes) or the entire sole of the foot. Sometimes scaling is severe, with breakdown and painful cracking (fissuring) of the skin. Fluid-filled blisters can also form. Over time, the skin on the soles may thicken.

Treatment of Athlete's Foot
Antifungal drugs applied to the skin or occasionally taken by mouth
Measures to keep the feet dry
The safest treatment of tinea pedis is using antifungal drugs that are applied directly to the affected area (topical). However, tinea pedis commonly recurs, and people often have to use antifungal drugs for a long time. Antifungal drugs taken by mouth (oral), such as itraconazole and terbinafine, are effective but may have side effects. To possibly reduce recurrences, topical and oral antifungal drugs may be used at the same time.
Reducing moisture on the feet and in footwear helps prevent recurrences. Wearing open-toe shoes or shoes that “breathe” and frequently changing socks are important, especially during warm weather. Spaces between toes should be thoroughly towel-dried after bathing. To help keep the feet dry, people may apply antifungal powders (such as miconazole), gentian violet, or aluminum chloride solution or soak their feet in Burow solution (aluminum subacetate).
