In the days leading up to the London Marathon 2026, On introduced LightSpray through a striking activation at Hanover Square (from April 24th to 26th, 2026), turning a temporary space into a working arena for running technology and experimental shoe design. The project brought process into full view, inviting visitors to follow the path from idea to performance with unusual immediacy.
Where running technology becomes performance
At its centre stood the LightSpray robot—mesmerising in its precision—condensing nearly 200 manufacturing steps into a single, continuous motion. Within minutes, ultralight uppers emerged, forming models such as the Cloudboom Strike and Cloudmonster 3 Hyper. The act of making unfolded with a quiet rhythm, closer to choreography than industry.
Around it, the space opened into a sensorial environment where movement, sound, and material intersected. Guests tested the shoes, joined guided sessions, and encountered audio pieces featuring Hellen Obiri, grounding the technology in lived athletic experience. Collaborations with Healf extended the focus toward recovery and collective wellbeing.
LightSpray and the future of shoe design
Rather than a conventional launch, LightSpray proposed a shift in how shoes are conceived and produced—reducing waste, refining construction, and bringing fabrication into the open. With its seamless, laceless structure, the system points toward a more immediate, adaptive approach to design.
For three days in London, innovation unfolded in real time—layer by layer, gesture by gesture.
