On Unveils Next Generation of Cloudboom Marathon Racing Shoes, Powered by New CloudTec Sphere™ Technology

Zurich, Switzerland, June 26, 2026 – Swiss sportswear brand On returns to the forefront of long distance racing with the second generation of the marathon winning Cloudboom franchise, introducing the Cloudboom Strike 2 and the LightSpray Cloudboom Strike 2. Engineered for marathon racing at the highest level, the Cloudboom franchise combines athlete insight with the science of running efficiency to maximise and sustain speed over the full marathon distance.
In its second generation, the Cloudboom Strike introduces a major evolution to On’s proprietary CloudTec® foam engineering system: CloudTec Sphere™. The geometry of CloudTec Sphere™ features engineered cushioning channels designed to enhance comfort and optimize running efficiency, supporting endurance and speed during long-distance racing. The system is complemented by the Helion™ hyper foam (HF) Midsole which is 15% lighter than the first generation of Cloudboom Strike.
Utilising On’s pioneering upper technology, the technical features of the LightSpray Cloudboom Strike 2 combine to create a 1.6% increase in running economy when compared to leading industry benchmarks, as proven in a recent study by the University of Cape Town. The shoe is already a proven success, helping six of On’s leading athletes to achieve personal bests, with recent marathon PBs from On athletes including: Hellen Obiri who improved her time by 1 minute 48 seconds in London, Yeman Crippa who secured a tactical victory in Paris with a 48 second improvement, and Joe Klecker who smashed through his personal best by 4 minutes and 41 seconds in Boston.
“The results we’ve already seen from athletes competing in the LightSpray Cloudboom Strike 2 reinforce On’s position at the forefront of elite road racing innovation,” says Nils Arne Altrogge, Senior Director of Innovation at On. “Our brief for the Cloudboom Strike 2 was not just about maximising speed, but sustaining it as athletes approach the crucial closing stages of a marathon. By combining our LightSpray™ upper with new CloudTec Sphere™ technology, we’ve engineered a unique fresh-leg advantage that helps athletes maintain performance deep into the race.”

About Lightspray
LightSpray™ condenses traditional upper manufacturing – which can typically require around 200 steps across multiple facilities – into a fully automated, single-step process. Using a robot arm, the innovative technology sprays 1.5 kilometers of a specialized filament to produce an ultra-light, seamless, one-piece upper in just minutes.
According to a prospective life-cycle assessment prepared by Vaayu, the localized, single-step process requires less manufacturing space, generates less waste, and reduces the carbon footprint by up to 65% when comparing the upper of the LightSpray™ Cloudmonster 3 Hyper to its conventional equivalent, showcasing the true potential of LightSpray technology.
Since introducing LightSpray™ in 2024, On has scaled its operational framework for automated shoe production from the ground up. The brand unveiled the world’s first LightSpray™ production facility in Zurich in 2025. This was followed by the opening of a second robot production facility near Busan, South Korea, in April 2026.
