The On Cloudboom Strike 2 Unisex Shoes are your marathon secret weapon, built for the moments when every second counts. Designed for competitive runners chasing faster times, this super-shoe combines explosive energy return, race-ready stability, and a featherlight feel to keep you moving with purpose from the starting line to the final sprint.

Underfoot, the CloudTec Sphere cushioning system engineered for fast runs works with the Lighter, resilient Helion HF hyper foam for energy return to create a responsive, springy ride that helps soften the impact of every stride. A curved Carbon Speedboard for propulsion drives you forwards, while the Adaptable, breathable open-weave upper keeps your foot secure and well ventilated when the race heats up.

Co-created with athletes, the Strike 2 is fine-tuned for high-level racing, with a Removable top midsole providing a soft, responsive ride and a High-grip rubber outsole for confident traction across dry pavement and wet city streets. At just 191g with a 5mm drop, it keeps the package light, fast, and ready for your next breakthrough.

What's New: Cloudboom Strike 2 vs. Cloudboom Strike

• Revolutionary Midsole Geometry: The Strike 2 introduces the CloudTec Sphere cushioning system engineered for fast runs, replacing the previous CloudTec configuration with a segmented design for smoother compression and rebound.
• Upgraded Super Foam: The new Lighter, resilient Helion HF hyper foam for energy return is 15% lighter than its predecessor, helping create a more energetic and responsive ride.
• Refined Carbon Plate: The updated Carbon Speedboard for propulsion is curvier and stiffer, enhancing the shoe's forward-driving feel compared with the flatter plate of the original.
• Enhanced Upper: Replaces the traditional mesh with an Adaptable, breathable open-weave upper, improving airflow, foot lockdown, and overall weight.
• Weight Reduction: Optimised foam, plate, and upper construction bring the Strike 2 down to an impressive 191g, giving you even more reason to chase that extra second.
