Tinea pedis is a pedal fungal infection commonly caused by T. rubrum. It can present interdigitally between the toes, in a moccasin distribution on the plantar foot, or a vesicular presentation either dorsal foot or plantar arch (see Figure 3). Patients will complain of an itchy and scaly rash that moisturizer doesn't diminish. T. rubrum is encouraged by humid climates, sweaty feet, and the use of shared spaces, like locker rooms. Over-the-counter treatments are typically effective and are terbinafine, butenafine, and clotrimazole creams. For more stubborn cases, both topical and oral antifungals can be prescribed. Regular changing to clean and dry socks and avoiding bare feet in public showers helps in prevention and recurrence (Page et al., 1991).
