KIPRUN KN500 kids' drop 0 running shoes - green yellow black

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.

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.
