Product Details

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 we call a Bounceboard - propel you forward with power. Design: - 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 In-Shoe Comfort: - 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 - Strategically-placed CloudTec® elements create a faster, smoother roll-through, while the ultra-cushioned ride protects against impact - 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
