There are basically 2 types of running shoes: cushioned ones and minimalist ones. Minimalist running shoes don’t have a thick cushioned heel like most cushioned running shoes, and they also reduce chronic leg injuries because they allow a runner to land more forefooted, with less instantaneous loading and vertical impact forces.
How Minimalist Running Shoes Reduce Lower Leg Injuries
Sinclair et al. (2014) found that runners in heelless shoes had a higher plantarflexion angle at foot strike which led to a reduction in the impact force parameters associated with most chronic injuries.
The researchers also found that minimum shoes greatly reduced the vertical impact peak and the instantaneous loading rate compared to traditional running shoes.
- The zero-drop profile of a minimalist running shoe plays a part in reducing shin splints by increasing plantarflexion moments at the ankle upon touchdown.
Flatter Foot Placement
Minimal shoes were effective in mediating a flatter foot placement compared to a heeled running shoe.
- A flatter foot placement in forefoot running lowers vertical impact peaks and instantaneous loading.
- Essentially, the foot is better able to strike the ground on the balls of the foot in forefoot running shoes.
However, high ankle dorsiflexion moments due to a heeled running shoe causes the foot to make direct contact on the heel first and not on the forefoot.
This is why it is critical to wear heelless shoes for forefoot running because they allow for better control over the movement and range of motion of the foot. A heeled running shoe fixes the foot-ankle complex in one position only, and that position facilitates a heel strike landing.
The Take Home Message
The notion that heeled running shoes stop injury has been knocked down around in the literature for the last decade. Yet, recent findings have compelling clinical significance because zero drop minimalist footwear reduce the impact peaks speculated to be the sole perpetrator of most running injuries.
From an evolutionary perspective, humans are fundamentally resistant to running injury if the proper foot strike is adopted. But to do so requires going barefoot or to run in a shoe that mimics the barefoot experience.
Nonetheless, heeled running shoes interfere with our innate ability to interact safely with the ground during running and should be thought of as a liability rather than a training aid.

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.
