What about the natural stride?

In order to make the stride natural and as similar as possible to running barefoot, the FLEX RUN shoe uses the following 4 criteria:

- A zero drop and flexibility, so that the middle of the foot strikes the ground first, rather than the heel

- Low weight for a smoother stride

- An anatomical shape to reduce the stresses of the shoe on the foot



Result: the energy from the ground contact is transmitted to the muscles at the back of the legs, which absorb vibrations better.

What's zero drop?

The drop of a shoe is the difference in sole height between the forefoot and the heel. Scientific studies conducted by our research lab (the SportsLab) have shown that a zero drop allows for a more natural stride, similar to a barefoot running stride. This natural stride allows for better absorption of shock waves when running and strengthens your kid's muscles and tendons in the long term.
