One way in which certain running shoes can hurt your feet is that when you constantly drive a big, inflexible wedge between your foot and the ground when you run, your arches actually become weaker because they become functionally disengaged from their spring-like properties. Also, in most conventional running shoes with stability constructs and stiff cushioning, the overall engaging activity of the foot’s muscles, tendons and soft tissue groups is more offline and is barely adequate to sustain strong muscle tone, healthy muscle volume and optimal functional health. This is how arch height and function gets worn down whereby running with flat feet may cause dangerous rises in pronation (abnormal foot motions during stance), impact production and balance instabilities.

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.
