On Running (aka On) is the young Swiss high performance brand with one aim: to change the world of running. Since its founding in 2010, On has won millions of dedicated enthusiasts around the world, including medal winners at World Championships and the Olympic Games. Tennis great Roger Federer is a fan. The key is On's patented CloudTec technology which aims to help the wearer feel as if they're running on a cloud. It's not hard to see the appeal.
The secret to On's success is a simple idea: cushioned landing for each foot, with a firm take off. That was the concept when former professional athlete Olivier Bernhard teamed up with his friends David Allemann and Caspar Coppetti to become business partners in a bold venture designed to challenge the domination of the multinational sportswear brands. It was a bold quest, and one that's paid off not only in medals won by On-wearers but in the ease and speed that On devotees achieve with these unique Swiss trainers.
On's high performance running footwear generally fits true to your usual size. On themselves, however, recommend that with their acclaimed waterproof range that you go up one on your usual size. The company's range of sweat pants are cut to an athletic fit and if you're prefer a more relaxed style, go up a size. If in any doubt, why not order two to find your ideal On fit?
