How LightSpray™ is changing the game
Yes, this robot sprays an upper. In just three minutes.
For decades, the sportswear industry has relied on a multi-step process to create shoes for athletes and fans. But LightSpray™ changes the game. Designed for elite-level running, our robot fuses 1.5km of filament onto a high-performance racing midsole. It forms a complete shoe upper in a single, three-minute step. No glues or seams means a 75% reduction in CO₂ emissions*, compared with our other racing uppers. You’ve never seen shoes made like this before.
With LightSpray™, we created our lightest upper yet. Weighing in at just 30g, it marks a new chapter for performance running. No laces mean fewer distractions. And the second-skin fit reduces chafing, so you can focus on the miles ahead – whether it’s 26.2 or more. By pairing this revolutionary upper with a propulsive bottom unit, we created the Cloudboom Strike LS. Featuring a carbon-fiber Speedboard® between two layers of Helion™ HF hyper foam for high energy return and impact absorption. Seen on podiums in Boston, Paris, New York, and Tokyo, it’s making strides around the world.
How it works
Removing excess steps and textiles, LightSpray™ transforms raw materials into something extraordinary.
LightSpray™ technology allows for glueless bonding and involves more than seven pending patents.
We cut out all unnecessary excess and processes. Like yarn and textile formation, conventional coloration, or increased water consumption.
The result? Less waste, fewer parts…
To make our fastest, lightest shoe.
