We sit down with On brand rep Mark Werhman to discuss On running shoes. Through countless experiments (some of them involving pieces of cut-up garden hose), The Creators of On created a shoe that first amazed and has since delighted the running world. Ons are not just a new running experience: they are far more than that. And the company's three co-founders have become ambassadors of a new running sensation whose success has far outpaced their expectations.
