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: 240 g in size 5.5.

For long-lasting running performance with optimum comfort, we have developed 2 concepts:
- K-Ring: a ring located in the heel improves rear cushioning and disperses the shockwave to protect the body (joints, back, knees, etc.) effectively
- Kalensole: Exclusive foam, developed with our R&D department improves cushioning by 34%, delivers 25% more energy response than traditional foam and offers durability of 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.

Comfort is a key factor for regular, long-distance runs.
We have sought to improve this comfort with:
- a new collar at the back of the shoe ensuring excellent heel support and ideal softness.
- a pre-shaped sole made out of PU (polyurethane) open-cell foam.
- a reworked forefoot area for more comfort.
- a single piece of fabric with no seams to reduce rubbing.

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.

Its exclusive K-ONLY concept with denser foam under the first metatarsus is suitable for all stride types (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.
Some figures from the study:
- 372 runners
- over 12,558 training sessions
- 12,094 hours of running
- 116,723 km covered

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

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 passionate about running, develop your Kiprun shoes with a network of ambassadors: runners at Decathlon, sports coaches and yourself!
