On's ultrafast Cloudboom Strike, now with their lightest LightSpray upper. Get ready for serious 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 On has ever made. 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 their other premium uppers. Invented in On's lab – for the future. 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, On maximized traction on the outsole, by increasing the ground contact in key areas. Product Highlights 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.
