One reason heel strike running may not always pay off for injury prevention is that it may cause hyper pronation which may lead to higher rates of impact unloading across multiple sites on the lower leg. This is because as the body-weight travels heel-to-toe after heel strike, the arch collapses too much which may cause abnormal foot motions that may result in insufficient impact absorption, and may keep injuries going as compared with forefoot running.

BSc Neurobiology; MSc Biomechanics candidate, ultra minimalist runner & founder of RunForefoot. I was a heel striker, always injured. I was inspired by the great Tirunesh Dibaba to try forefoot running. Now, I'm injury free. This is why I launched Run Forefoot, to advocate the health & performance benefits of forefoot running and to raise awareness on the dangers of heel striking, because the world needs to know.
