The Kalenji team includes runners of all levels of ability. Every day, we test our products to try them out and improve them. They are then tested by a panel of users under the real-life conditions for which they are designed. Before you put them on, they have already covered several thousands of kilometres and completed hundreds of races ranging from 10 km to the marathon distance.
All our shoes are field tested for wear and comfort by male runners not associated with Decathlon. The aim is to test, improve and validate the product as objectively as possible so that you can run without a problem.
