How to Prevent the Most Common Running-Related Foot and Ankle Injuries
Running is one of the most accessible, effective, and rewarding forms of exercise available — but it is also one of the highest-impact activities the feet and ankles endure. The repetitive nature of the running stride, combined with the significant forces each foot absorbs with every step, creates a unique injury profile that affects a large portion of runners at some point in their training. According to research published in the British Journal of Sports Medicine, between 37 and 56 percent of recreational runners sustain a running-related injury in any given year. The good news is that the majority of these injuries are preventable with the right approach to training, footwear, and biomechanics.
Here is a practical guide to the most common running-related foot and ankle injuries — and what you can do to stay healthy and on the road.
1. Plantar Fasciitis
Plantar fasciitis is the most common running injury treated in podiatric practices. It develops when the plantar fascia — the fibrous band of tissue along the bottom of the foot — is subjected to more repetitive stress than it can handle, leading to micro-tears and inflammation at the heel attachment. Runners who increase their mileage too rapidly, wear worn-out or inadequately supportive shoes, or have biomechanical factors like flat feet or tight calves are particularly vulnerable.
Prevention tips: Increase weekly mileage by no more than 10 percent per week. Stretch your calves and plantar fascia daily — particularly before running and first thing in the morning. Wear running shoes appropriate for your foot type and replace them every 300 to 500 miles. Consider custom orthotics if you have flat feet or overpronation, as these significantly reduce strain on the plantar fascia.
2. Achilles Tendonitis
Achilles tendonitis is inflammation of the Achilles tendon — the large tendon connecting the calf muscles to the heel bone. Runners who ramp up training too quickly, run in worn shoes, or have tight calf muscles and limited ankle flexibility are at elevated risk. The condition is particularly common in middle-distance and marathon runners during heavy training phases.
Prevention tips: Incorporate regular calf stretching and eccentric heel-drop exercises into your routine — research from the Scandinavian Journal of Medicine and Science in Sports has demonstrated eccentric exercises to be highly effective in reducing Achilles tendon pain. Avoid running in minimalist shoes without proper transition time. Never ignore early warning signs of Achilles pain — early intervention prevents a more serious injury.
3. Stress Fractures
Metatarsal stress fractures are small cracks in the bones of the foot caused by repetitive impact forces that exceed the bone’s ability to remodel. They are particularly common in the second and third metatarsals and in the navicular bone. Runners who increase training load too rapidly, run on hard surfaces, have low bone density, or wear shoes with insufficient cushioning are most at risk. Stress fractures produce a localized, aching pain that gradually worsens over days or weeks and is tender to direct touch over the bone.
Prevention tips: Follow the 10 percent rule for mileage increases. Ensure adequate calcium and vitamin D intake to support bone density. Rotate between two pairs of running shoes to vary impact patterns. Include rest days and cross-training in your schedule to allow bones adequate recovery time. If you develop localized bony pain, stop running and seek evaluation immediately — running on a stress fracture can cause a complete break.
4. Ankle Sprains
Ankle sprains are among the most common acute injuries in trail runners and those who run on uneven surfaces. They occur when the ankle rolls beyond its normal range of motion, stretching or tearing the lateral ligaments. Runners with a history of previous ankle sprains are at significantly higher risk of recurrence due to residual ligament laxity and proprioceptive deficits.
Prevention tips: Strengthen the muscles around the ankle with balance and proprioception exercises — single-leg balance drills are particularly effective. Choose trail-specific footwear with appropriate ankle support and traction for off-road running. Fully rehabilitate any ankle sprain before returning to running — incomplete rehab is the leading cause of chronic ankle instability. Consider ankle bracing for high-risk terrain if you have a history of sprains.
5. Sesamoiditis
Sesamoiditis is inflammation of the sesamoid bones — two small bones embedded in the tendon beneath the big toe joint. It produces pain at the ball of the foot, particularly during push-off, and is common in forefoot strikers and sprinters. Runners who wear shoes without adequate forefoot cushioning or who dramatically increase speed work are most vulnerable.
Prevention tips: Ensure running shoes have adequate cushioning under the forefoot. Avoid sudden increases in speed work or hill training. If you feel pain under the big toe joint, address it early — sesamoiditis can become a chronic, limiting condition if ignored.
The Most Important Rule: Do Not Run Through Pain
The most consistent risk factor for serious running injuries is ignoring early warning signs and continuing to train through pain. Minor discomfort that persists for more than a few days, pain that alters your gait, or swelling that does not resolve with rest are all signals that your body needs attention — not more miles.
