Built for your fastest half- and full marathons, the Cloudboom Strike revolutionizes the racing experience. Ultra-responsive Helion™ HF hyper foam and an innovative drop-in midsole – which On calls a Bounceboard – propel you forward with power.

Product Highlights

• Race-specific CloudTec®. Strategically-placed CloudTec® elements create a faster, smoother roll-through, while the ultra-cushioned ride protects against impact. The result? Increased running efficiency.
• Cushioned Bounceboard. Functioning like a drop-in midsole, the innovative Bounceboard boosts the shoe's stack height for maximum energy return – all while abiding by stack height regulations.
• Ultralight upper. Ultralight and breathable, the one-piece, semi-transparent mesh upper helps to reduce overheating. The cage-like construction locks down the midfoot for a secure, race-ready fit.
• Carbon fiber Speedboard®. Made with stiff carbon fiber, the spoon-shaped Speedboard® works like a spring, absorbing energy and transferring it into the forefoot for the most powerful take-offs possible.
