About the brand

ON was the brainchild of professional, three-time world duathlon champion and multiple Ironman winner, Olivier Bernhard. His retirement mission was to create the perfect running trainer with the idea that a cushioned landing but firm take-off would create the perfect running sensation.

It was this idea that convinced friends Caspar Coppetti and David Allemann to join him in launching the ON brand in January 2010. From small beginnings in Zürich, Switzerland they set out to change the world of running.

Are ON Sustainable?

Sustainability has always been a core brand value for ON, they see that performance and sustainability go hand in hand, using innovation to create sustainable solutions. Born in the swiss alps, sustainability is deeply rooted in the founder’s personal values due to their huge appreciation for the natural world. Their ethos is shared with everyone in their company with all of their team contributing to their sustainable goals. As they are a small business their strategy is to focus on getting the basics right and focus on the areas that will have the most impact. This is one of their most recent projects… 

The CleanCloud

CleanCloud is the new high-performance foam for running shoes, reshaping carbon waste into raw material. Collaborating with a supply chain coalition in cooperation with LanzaTech and Borealis. 
  • The process starts with LanzaTach capturing carbon emissions from industrial sources. 
  • Then they convert emissions into liquid ethanol using a fermentation process. 
  • The ethanol is then dehydrated turning it into ethylene gas, which is then polymerized by Borealis to create EVA pellets. 
  • ON then uses this EVA to engineer high-performance foam cushioning for running shoes: CleanCloud. 

The difference between the Cloud 5 trainer and Cloudnova trainer?

The Cloud 5 is a road running trainer that is designed for soft landings and powerful push-offs allowing you to go the extra distance. The trainer is made from 44% recycled lightweight, breathable materials making it easy to wear and easy on the environment.

This style is an everyday running trainer that has been re-engineered for an improved fit and comfort. Key design features include the speed lacing system instantly locking you in, meaning you never waste any time sorting your laces.The Cloudnova is a new performance-led design, combining responsive comfort and urban energy that you can last in all day. The trainer has an inner sock design providing support and comfort with a padded heel and customized lace configuration. The rubber reinforcements support your foot's natural rolling motion and the tongue provides a great fit.

Comparing the two styles, the Cloud 5 has speed laces whereas the Cloudnova has standard laces. The Cloud 5 is better in warmer conditions whereas the Cloudnova will be better in colder climates. Both trainers are perfect for everyday wear, exploring, exercising and travel. The Cloudnova is the heavier trainer with a slightly smaller heel depth.

What's the difference between Cloudswift and Cloud 5 on running trainers?

We wanted to compare these two styles due to an increase in popularity. However, these trainers are being worn as everyday trainers and not just for high-performance workouts or running. Watch our YouTube video giving you all the details.
