On returns to the forefront of long distance racing with the second generation Cloudboom Strike 2 and the LightSpray Cloudboom Strike 2.
Engineered for 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.
“The results we’ve already seen 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.”
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. Recent marathon PBs from On athletes include: 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.
