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

The research and development studies have shown that a lighter product improves running performance by reducing energy consumption. To design the KS LIGHT, there was no compromise in terms of comfort and durability and the decision was taken to use lighter components and an optimised sole design. As a result, The KIPRUN KS LIGHT shoe is 12% lighter than the KIPRUN LONG. Weight: 290 g in size 9.

To give you optimal comfort and performance when running, we concentrated our attention on the sole which features 2 concepts: - K-Ring: ring located in the heel to improve the 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 propulsion 25% compared with standard foam and lasts up to 1,000 km.

A stable shoe that facilitates the roll-through of the foot and reduces the effort needed to control the foot and the heel for a more relaxed foot motion. We have increased the surface supporting the foot and added reinforcement at the back of the heel.

In order to run regularly over long distances, foot comfort is of the utmost importance. We have therefore sought to improve the level of comfort thanks to the following: - a new collar at the back of the shoe ensuring excellent heel support and ideal softness. - 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 effective running without any loss of control when it rains. 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 top speed.

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 or 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 running hours - 116,723 km covered

The Kiprun KS Light is the product of footwear expertise acquired over more than 10 years at Decathlon. Caroline and Pierre-Emmanuel (product managers), Stéphane (product engineer) and Nicolas (designer), who are all running enthusiasts, designed 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.
