On’s next-generation marathon racer is built around one goal—keeping speed intact when the kilometres start to stack up. The Cloudboom Strike 2 introduces a new CloudTec Sphere™ cushioning system, designed with engineered channels to enhance impact absorption and rebound while helping maintain efficiency deep into a race. A lightweight open-weave upper keeps the fit secure and breathable, while the updated Helion™ HF hyper foam midsole is 15% lighter than its predecessor for a faster, more responsive ride. Sitting between dual-density foam layers, the curved Carbon Speedboard® has also been refined to be lighter and stiffer than previous versions, driving a more powerful toe-off with every stride.
