- A confirmed clinical diagnosis of tinea pedis with lesions localized to the interdigital spaces or predominantly interdigital, but may extend to other areas of the foot.
- The presence of tinea pedis infection, confirmed by the observation of segmented fungal hyphae during a microscopic 10% potassium hydroxide wet mount examination.
Exclusion Criteria:
- Females who are pregnant, lactating or likely to become pregnant during the study.
- Use of antipruritics, including antihistamines within 72 hours prior to baseline visit.
- Use of topical corticosteroids, antibiotics or antifungal therapies within 2 weeks prior to baseline visit.

- Confluent, diffuse moccasin-type tinea pedis of the entire plantar surface.
- Significant history or current evidence of chronic infectious disease, system disorder, organ disorder, or other medical condition that would place the patient at undue risk by participation or could jeopardize the integrity of the study evaluations.
- Evidence of any concurrent dermatophytic infection of the toe nails or dermatological condition of the foot that may interfere with the evaluation of tinea pedis.
- Patients with a past history of tinea pedis infections with a lack of response to antifungal therapy.
- Patients who would be non-compliant with the requirements of the study protocol.
