On Running Cloudboom Strike LS

Our ultrafast Cloudboom Strike, now with our 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.

Over 40% bio-based Helion™ HF hyper foam for high-speed energy return
