The height difference between the back and front of the sole is 8 mm.

The research and development studies have shown that a lighter product improves running performance by reducing the consumption of energy. No compromise was made on comfort and durability but the design of the KD LIGHT uses lighter materials and optimised sole design. Result: The KIPRUN KD LIGHT shoe is 9% lighter than the KIPRUN FAST. Weight: 256g in size 9.

For long-lasting running performance with optimum comfort, our R&D teams have developed this special foam which meets the needs of runners' needs and guarantees cushioning for 800 kilometres. The Kalensole foam improves cushioning by 34% and energy response by 25% when compared with standard conventional foams.

Better performance and times in the 10k marathon thanks to the UP'BAR technology and TPE (Pebax®) located under the sole, the KIPRUN FAST improves dynamism (rebound) and provides additional propulsion with each stride.

In order to run regularly over long distances, foot comfort is of utmost importance. We have therefore sought to improve the level of comfort with the following: - a new collar at the rear of the sockliner holds the heel securely in place in the shoe so that it feels extremely snug. - a preformed sole made of open-cell PU (polyurethane) foam. - a reworked forefoot area for more comfort. - a seamless, single piece of fabric to reduce friction.

Our sole was designed like a car tyre for running efficiently without losing control, even when it is raining. The new sole geometry combined with a new rubber component gives the KIPRUN KD LIGHT excellent grip on wet ground, even when running at top speed.

The Kiprun KD Light is the product of Decathlon footwear expertise acquired over more than 10 years. Caroline and Pierre-Emmanuel (product managers), Stéphane (project engineer) and Nicolas (designer), who are running enthusiasts, develop your Kiprun shoes with the help of a network of ambassadors: the runners at Decathlon, sports coaches and you! In this way, we choose the components, create the prototypes and test and validate the products with laboratory and field tests.
