Dry feet (cracked heels)
Dry feet are common in winter and summer, especially cracked heels, which can be painful when soaps, dirt, or chemicals get in. Over-the-counter products can help a lot.
Athlete's foot
Athlete’s foot is a fungal rash that usually itches, with peeling skin between the toes and dry patches on the feet. Painful cracks called fissures can form. Most cases improve with over-the-counter treatments.
