On shoes co-founder Olivier Bernhard reveals how it became running’s most innovative brand

Last month, Kenyan long-distance runner Hellen Obiri set a course record at the New York City Marathon, clocking 2:19:51. She didn’t only break the old record – she obliterated it by two and a half minutes. And she did so while wearing the Cloudboom Strike LightSpray shoes by On.

A few days later, the exhilaration is still palpable during a chat with On co-founder Olivier Bernhard. “Emotional rollercoaster,” he says. “It gets me every time. Maybe because I’ve been there myself, I have literally been in their shoes. I wish I had run the marathon – probably would’ve been easier than just watching it.”

Obiri’s achievement delights him. “This is what sport is all about. It’s so honest and authentic.”

Bernhard knows exactly what it takes to reach such heights. Before launching On in 2010 with friends David Allemann and Caspar Coppetti, he was a professional athlete – three-time world champion, European champion and 15-time Swiss champion in duathlon and Ironman events. That experience informed the company’s founding mission: to create the ultimate performance footwear.

Searching for the perfect balance between cushioned landing and explosive lift-off, Bernhard began by stapling pieces of garden hose to the soles of shoes. Those experiments evolved into On’s signature CloudTec cushioning: hollow pods that absorb landing energy, then lock together to generate powerful propulsion. Because the pods compress both vertically and horizontally, each shoe adapts to a runner’s individual style.

It was this breakthrough that attracted Swiss professional tennis player Roger Federer, who joined the company as an investor and collaborator in 2019.

Professional insight remains On’s competitive edge, Bernhard says. “Feedback is what allows us to lift every product to the next level. I was a professional athlete, but I was not asked for feedback. It’s a waste of knowledge, as I was the one at the end of the chain demanding the most of the product.”

But building for elite competition comes with pressure. “The dream is to deliver the best power possible. But the New York City Marathon or Olympic Games come with a date. So we have to not only deliver the shoe, but also deliver it when the athlete needs it.”

On’s reputation for performance and coherence continues to grow. Every product is clearly defined by purpose – the Roger for tennis hard courts, the off-road Cloudvista 2 for wet, mixed terrain, the Cloud 6 Waterproof for daily wear. Clothing ranges from ultralight windproof jackets to heat-wicking tops designed for wider training temperatures.

Innovation sits at the centre. The Cloudboom Strike LS worn by Obiri – also used when she took bronze at the Paris 2024 Olympic marathon – is built with On’s new LightSpray technology. A robotic arm winds a continuous thermoplastic thread around a carbon-fibre mould, producing a featherlight, seamless, sock-like shoe in just three minutes, weighing only 170g. “LightSpray is not just another product; it’s a revolutionary long-term innovation, because it’s a new way to make shoes,” Bernhard says.

It’s sustainable, too. The process uses less material, requires smaller machinery and could allow On to create micro-hubs where shoes are made locally, cutting ship
