Science tells us that by impact standards, a high collision force as well as greater joint loading are consistent consequences of heel strike running whereby at faster running speeds, all this impact may boil into pain and fatigue which may in turn, complicate running economy and your injury prevention efforts. Read more here about how heel strike running has more negative forces at work on the leg 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.
