On × Bang & Olufsen: Innovation, Design and Performance

It was not only the connection between sound and sport that sparked a collaboration between Bang & Olufsen and On, but a shared fascination in deepening human experience through design; Music and running are fundamental ways for us to experience the world. On 16 July, On launched its latest elite competition shoe, the “Cloudboom”, together with Bang & Olufsen’s first sports product, the Beoplay E8 Sport On Edition wireless headphones.

The racing shoe: Cloudboom

Developed specifically to fire you to your fastest-ever marathon, the Cloudboom features all-new innovations and Ons’ most explosive Speedboard® yet. This is the story behind its high-speed tech.

Carbon-Fiber Infused

As the name suggests, the Cloudboom is made for explosive speed. So On evolved their 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. 

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 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. 

Twin-Turbo CloudTec® 

The Cloudboom is the first shoe ever to feature an additional layer or the award-winning CloudTec® technology above the Speedboard®. This effectively creates a completely new midsole configuration, created specifically for a responsive yet comfortable racing sensation. 

No Upper Speed Limit

For raceday an ultralight breathable upper is a must, and it hopefully goes without saying that you get that with the Cloudboom. Using just a single layer of engineered mesh keeps weight to a minimum while maximizing breathability. 

The upper of the Cloudboom is also structured specifically for the demands of marathon racing on the road. 

A lot of road marathons, particularly the major races, take place on city streets. As a result, the corners are usually very tight and require you to turn quickly at pace,

Kevin explains.

“When we looked at this detail we saw our athletes are pushing a lot of force through certain sections of the upper on these turns. By using engineered mesh we are able to add reinforcement at exactly these points – and only these points– for added comfort and protection while keeping down weight and increasing airflow.”

The Sound of Unstoppable

Swiss-engineered to bring explosive pace to marathon distance, every detail of the Cloudboom has been created to power elite athletes onto podiums and you to a new personal best. Also ideal for long interval sessions and tempo training, as well as racing at half marathon distance, it’s your new weapon in the hunt for discovering a whole new world of speed. Boom.

Not only can you stay plugged in on wet-weather runs, but waterproof materials mean keeping your earphones clean is simple. Maintain that box-fresh feel for longer. 

Secure and fully customizable

Bang & Olufsen know there’s no one-size-fits-all when you’re creating a high-end product. To achieve a truly premium listening experience, earphones should be anatomically shaped to each wearer. That’s why with each set of Beoplay E8 Sport On Edition earphones, there’s four pairs of silicone ear tips and three pairs of ear fins for a secure, tailored fit.

The Beoplay E8 Sport On Edition by On × Bang & Olufsen is more than premium technology, it’s a sophisticated design piece. Choose between classic black or vibrant blue, both offering a noticeably premium monochrome style to your run or all-day wear.
