The most common foot problems caused by sports-related activities are blisters, corns, Cellulitis, athlete’s foot, achilles tendonitis, and heel pain. Preventive measures include using proper foot hygiene: keeping your feet dry, wearing clean socks, making sure your shoes fit properly and making sure you do not overstrain your legs, ankles, and feet. If you develop recurring and/or increasing aches and pains you should make an appointment as soon as possible to avoid causing permanent damage.
