One of the largest studies in the world.

For many years, researchers from around the world

have been studying shoe cushioning without knowing whether there was actually a link between shoes' mechanical cushioning properties, and injuries.

In 2018, Decathlon decided to conduct a study with

848 participants over 27,761 running sessions, in partnership

with the LIH (Luxembourg Institute of Health).

What was the purpose of the study?

To confirm the link between cushioning and injuries. In this study, two cushioning

conditions have been tested: A flexible shoe (61 N/mm) against a

stiff shoe (95 N/mm). The result of this study

speaks for itself: 25% fewer runners injured with the flexible shoe.

It is on the basis of this study that the flexible cushioning of the FLOW series was created, focusing on the preference index of soft cushioning.

WHAT IS THE DROP ON THE JOGFLOW 500.1 RUNNING SHOE?

'Drop' is the difference between the height of the back (heel) and front (forefoot) of the shoe. Unlike the 10mm drop on many running shoes, KALENJI has decided to use a drop of 4mm on its Jogflow 500.1 The goal? To encourage runners to strike the ground using the forefoot to help them adopt a more natural stride and reduce the risk of injury.
