K-RING: The K-RING is an exclusive heel cushioning technology in the form of a ring located in the heel. The hole in the middle disperses the shockwave.
KALENSOLE: the EVA foam used in the midsole. The result of three years of research to create an exclusive composition which improves cushioning by 34%, propulsion by 25% and provides better temperature stability and durability up to 1,000 km.
SUIT ALL TYPES OF STRIDES
K-Only: Exclusive Kalenji technology that makes our shoes suitable for every stride type thanks to the denser foam located under the first metatarsal.This innovative technology is the result of a six-month study with a sample of 372 runners conducted by the Luxembourg Institute of Health*. After 12,558 training sessions, 12,094 hours and 116,723 km of running, the study demonstrated that the K-Only technology suits all types of strides, whether they are pronator, neutral or under-pronator.
