Hear that? That’s the sound of your PR falling and records breaking. Of Swiss
engineering colliding with elite-athlete input to create the ultimate marathon shoe.
Developed specifically to fire you to your fastest-ever marathon, the Cloudboom features all-new innovations and our most explosive Speedboard® yet. This is the story behind its high-speed tech.
Striking the Balance
“Creating the ideal racing shoe for half marathon and marathon is a complex balancing act,” explains Kevin Dellion, Sport Science Lead in the On Innovation Team.
“Like with all our performance products, the starting point was input from elite On athletes. When you compete at a high level over long distances you want a fast, direct sensation. You don’t want to dampen the experience – you want to dial it up, get those input points that inform your performance."
“At the same time, you need cushioning to stay comfortable when you’re pushing yourself our of your comfort zone – especially towards the end of a long race like a marathon. Our goal was to strike that balance exactly. Direct yet cushioned. Comfortable but always powerful, from first mile to finish line. That’s what led us to develop the technology you see on the Cloudboom.”
As the name suggests, the Cloudboom is made for explosive speed. So we evolved our signature fast-firing Speedboard® for even more ‘boom’. Already explosive by design, the Speedboard® flexes every step, converting the energy you create on impact into forward motion. And in a marathon, you want to retain all the energy you can for that final kick.
That’s where the addition of carbon fiber comes in. Infused into the Cloudboom Speedboard®, it adds just the right amount of additional rigidity for a more powerful push-off while keeping the agile feel the Speedboard® is famous for.
Like with all On shoes, the Speedboard® is shaped specifically for the function of the shoe. In the Cloudboom, the Speedboard® is curved to create an extreme rocker profile. This optimizes rolling motion for even more propulsive power. Rocker? More like rocket.
The Cloudboom is the first shoe ever to feature an additional layer or our award-winning CloudTec® technology above the Speedboard®. This effectively creates a completely new midsole configuration, created specifically for a responsive yet comfortable racing sensation.
Several rounds of pro athlete feedback and numerous iterations later, Kevin and the team had the balance between soft landings and direct sensation dialed. The solution sees a layer of CloudTec® placed above the Speedboard® for the first time in an On shoe.
This initial layer not only delivers additional long-distance comfort, it also supports creates an instant fit. Together with the performance sockliner, the shoe adapts to your foot quickly after step in so you immediately feel ready to race.
