Several effective and inexpensive over-the-counter treatments are available for minor but troubling foot problems. In most cases, one week of therapy with topical terbinafine is effective for interdigital tinea pedis. Treatment of plantar warts with 17 percent salicylic acid with lactic acid in a collodion base is as effective as cryotherapy, but treatment must be sustained for several months. Toe sleeves and toe spacers can relieve pain from hard or soft corns. Metatarsal pads can relieve the pressure associated with plantar keratoses. Heel cups often can relieve pain caused by age-related thinning of the heel fat pad. Plantar fasciitis is a common cause of anteromedial heel pain caused by repetitive strain on the plantar fascia. Although the mainstay of therapy is stretching exercises, ready-made arch supports and insoles can be helpful adjuncts. [ABSTRACT FROM AUTHOR]
