On Brings its LightSpray™ Technology to London with an Immersive Public Experience at the Height of Running Season
The Swiss sportswear brand presents the UK debut of its LightSpray™ technology.
London, United Kingdom, 20 April 2026 – Swiss sportswear brand On brings its groundbreaking LightSpray™ technology to London for its UK debut with On LightSprayTM Tour London: an immersive experience at 3 Hanover Square, from April 24 – 26, featuring a hands-on look at the LightSpray™ story.
On LightSpray™ Tour London will welcome runners into an immersive world co-created by PlayLab – providing attendees with an exclusive look at the transformative potential of the revolutionary LightSpray™ technology and its journey from mind to podium. Runners will watch the LightSpray™ robot in action, before stepping into a data-driven product test run dubbed the “Dream Run”. The experience is further elevated by the immersive sound of insights from four-time marathon winner, Hellen Obiri, reflecting on her record-breaking run in New York. Throughout the programming, On athletes, ambassadors, and community members are expected to visit the space.
“London is one of the world’s most influential running cities, so bringing LightSpray™ here during marathon week feels like a natural next step for On. This technology represents a completely new approach to how performance footwear can be designed and produced, and it’s exciting to give the UK running community the opportunity to experience it firsthand” says Bianca Pestalozzi-Houchangnia, General Manager EMEA, On.
Celebrating the brand’s Real Energy campaign, On LightSpray™ Tour London goes beyond product demonstration with a series of community activations designed to extend energy return into a holistic experience. Wider programming is hosted in collaboration with Healf, a UK-based wellbeing platform that offers the world’s most intentional curation of wellbeing products.

The LightSpray™ Journey
Since introducing LightSpray™ in 2024, On has been building the operational framework for automated shoe production from the ground up. The LightSpray™ robot produces the upper of the LightSpray Cloudboom Strike – On’s lightest performance shoe to date – in just three minutes. What began as a four-year development journey, followed by the opening of On’s first factory, has now advanced production capacity 30-fold with the opening of its second facility near Busan, South Korea. As production scales, On plans to explore LightSpray™ applications in other categories, alongside new drops in 2026.
Product Details
The LightSpray Cloudmonster 3 Hyper, the first shoe upper sprayed at the Korean facility, is an ultralight all-round training shoe. Key features include a minimalist laceless LightSpray™ construction, designed to feel like an extension of the body. The ultimate super trainer features enhanced cushioning, comfort and hyper-responsiveness designed to support high-intensity training and faster recovery, weighing in at just 205g.
The LightSpray Cloudboom Strike is engineered for the long haul with an athlete-informed design that delivers exacting comfort, efficiency, and control over 42.2km. On’s lightest-ever racing shoe at 170g has soft propulsive cushioning that meets high responsiveness for sustained speed over full marathon distance.

About LightSpray™
LightSpray™ condenses traditional upper production—which typically requires approximately 200 steps across multiple factories—into a single, fully automated process. A robotic arm sprays 1.5 kilometers of specialized filament onto a last, creating an ultra-light, one-piece upper in around three minutes. The process requires less space than conventional manufacturing, is designed to generate less waste and produce uppers with a lower carbon footprint compared to On's other racing shoes, based on lifecycle assessments conducted by On.
