In order to run long distances while delivering maximum comfort and performance, we have devoted special attention to the sole using 2 technologies: - K-Ring: ring located in the heel to improve cushioning at the rear and spread the shockwave in order to effectively protect the body (joints, back, knees, etc.) .- Kalensole: improves cushioning by 34% and energy return by 25% when compared with conventional foam and lasts up to 1,000 km.

Better performance and times for all distances up to marathon thanks to the UP'BAR technology and TPE (Pebax®) located under the sole, the KIPRUN FAST 2 improves dynamism (rebound) and provides additional propulsion with each stride.

Thanks to the exclusive K-ONLY technology and denser foam located under the first metatarsal, you no longer need to know your stride type (over-pronator, under-pronator, neutral)! A 6-month study conducted with the Luxembourg Institute of Health* showed that the K-Only concept suits all strides. The key figures of the study: - 372 runners - over 12,558 training sessions - 12,094 hours of exercise - 116,723 km covered

Our sole is designed like a car tyre for running performance without losing control in wet conditions. The new geometry of the sole combined with a new rubber component provides the KIPRUN KS LIGHT with excellent grip on wet terrain, even at high speeds.

In 2020, we have improved the KIPRUN FAST 2 thanks to your feedback over the last 2 years: - new rubber on the outer sole for 35% more grip .- upper with harder-wearing mesh

The height difference between the back and front of the sole is 10 mm.

The Kiprun FAST 2 is the product of Decathlon's shoe expertise gained over 10 years. Caroline and Pierre-Emmanuel (product managers), Stéphane (product engineer) and Nicolas (designer) are all running enthusiasts. They designed your Kiprun shoes with the help of a network of ambassadors: the runners at Decathlon, sports coaches and you! We choose the components, create the prototypes, then test and validate the products with laboratory and field tests.
