Of course, you don't have much direct control over your footstrike. However, you should practice running in the most injury-free way, which includes landing mid-sole and then rolling through to the front of your toes. That's the safest way to run for most recreational runners. If you land on your heels, you're stopping your forward momentum and causing way too much stress and impact on your lower legs, which might result in shin splints.
Meanwhile, landing on your toes overworks your calf muscles, which can be another contributing factor to shin splints and other overuse injuries. Therefore, while running, ensure you are not striking the ground with your heel or your forefoot first. And remember, your foot should land below your hips – not out in front of you.
