made with top - notch materials

One pair per customer.

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, its the lightest upper weve 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 CO 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.
