On Opens The World’s First LightSpray™ Production Facility In Zurich
4 July 2025
This week, On formally inaugurated the world’s first production facility for its revolutionary LightSpray™ technology in Zurich. At an event On’s three co-founders, Caspar Coppetti, David Allemann, and Olivier Bernhard, unveiled the new LightSpray™ Factory. The facility houses four robots and enables On to manufacture all the uppers for its performance running shoes directly in Switzerland using fully automated and industrially scalable processes and procedures.
If you aren’t aware of this technology, LightSpray™ is a revolutionary tech for the manufacture of high-performance shoe uppers. It enables production by robots in a fully automated single-step process. While traditional shoe upper production involves some 200 steps and various locations, LightSpray™ uses a robot arm and 1.5 kilometers of filament to produce an ultra-light one-piece upper in just three minutes. The highly efficient process saves both space and time, minimises waste and produces an upper with 75% fewer carbon emissions than On’s other racing shoes.
