This is LightSpray™

Revolutionary technology. Lighter than humanly possible. 

Yes, the future of running is here.

LightSpray™ is revolutionizing performance running. By uniting robotics and material innovation, this unique technology cuts a multi-part process into a three-minute, minimal-waste step. The result? Our lightest racing shoe yet. The Cloudboom Strike LS weighs just 170g. No laces. No tongue. Only the essentials for speed and propulsion.

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.

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.

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.
