The ultrafast Cloudboom Strike, now with the lightest LightSpray™ upper. Get ready for serious pace. Seamless to set the pace - An ultra-thin, second-skin fit that's seamless, with enough support for race day. How? A single 1.5km long filament is spun by robot to create a mesh-like upper. Which is breathable and elastic, with no need for laces. And, at just 30g, it’s the lightest upper we’ve ever made. Sprayed to cut emissions - Creating the upper in a single piece not only creates a seamless, distraction-free fit. It also minimizes waste, eliminates the need for glues and emits 75% less CO₂ than our other premium uppers. Invented in our lab – for the future. Power and propulsion - Two layers of Helion™ HF hyper foam provide high energy return and impact absorption, with a pre-shaped, stiff carbon fiber Speedboard® sandwiched between, for powerful propulsion at every stride. And, we maximized traction on the outsole, by increasing the ground contact in key areas. - LightSpray™ technology for our lightest-ever upper - Made without a sockliner to maximize Helion HF content - Over 40% bio-based Helion™ HF hyper foam for high-speed energy return - CloudTec® elements create a faster, smoother roll-through - Seamless and responsive second-skin fit - Ultra-cushioned ride protects against impact - Spoon-shaped Speedboard® to absorb and transfer energy - Lace-free construction minimizes distractions.
