Foot Care for Runners: Prevent the Common Injuries
Running loads each foot with several times your body weight thousands of times per mile. A little foot care goes a long way to keeping you injury-free and on the road.
Why runners' feet need care
Repetitive impact makes runners prone to blisters, bruised toenails, plantar fasciitis, Achilles tendonitis, metatarsal stress fractures and more. Most are preventable with good footwear, gradual training and basic skin and nail care.
Blisters and black nails
Prevent blisters with moisture-wicking socks, properly fitted shoes (a thumb's width at the toe), and lubricant or tape on hotspots. Black toenails come from the nail repeatedly hitting the shoe front — usually a sign your shoes are too short or laced loosely. Keep nails trimmed straight across.
Overuse injuries
Plantar fasciitis, Achilles tendonitis and stress fractures usually trace back to doing too much too soon. Follow the rule of increasing weekly mileage gradually, include rest days, and treat early aches before they become injuries. The American Podiatric Medical Association (APMA) highlights gradual progression and proper shoes as key to preventing running foot injuries.
A runner's foot routine
- Inspect feet after long runs for hotspots and blisters
- Wash and fully dry feet, especially between the toes, to prevent athlete's foot
- Stretch and strengthen the calves and foot muscles
- Ice sore areas and address niggles early
Shoes and rotation
Replace running shoes roughly every 300-500 miles, rotate between two pairs to vary load and let cushioning recover, and choose shoes that fit your foot shape and gait. Worn-out shoes are a common hidden cause of foot pain.
