• Healthy male or non-pregnant, non-lactating female = 18 years of age.
• 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 non-interdigital lesions should not be hyperkeratotic, i.e., characteristic of tinea pedis moccasin).
• Provisionally confirmed at baseline by a positive potassium hydroxide (KOH) wet mount preparation
• Total score = 4 for the clinical signs and symptoms of tinea pedis in the target area. In addition the target area must have a minimum score of at least 2 for erythema and a minimum score of at least 2 for either pruritus or scaling.

Exclusion Criteria:

• Presence of any other infection of the foot or other disease process that, in the Investigator's opinion, may interfere with the evaluation of the patient's tinea pedis
• History of or current psoriasis, Lichen planus or contact dermatitis involving the feet within the previous 12 months.
