Not all running shoes are bad for your feet. Just the ones that counter the natural anatomy and functionalities of the feet. For example, stiff, narrow running shoes restricts arch mobility which means the arch can no longer contribute to impact absorption efficiently because it has disrupted spatial ability to compress, bend and extend. A key consequence of this scenario is that impact may build up while running of which the lower leg may bear the expense of this, and may quickly make you injury prone. This is one reason tying your feet up in stiff, narrow running shoes may be unhelpful for injury prevention as compared with minimalist running shoes. Read more here!
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.
