On was born in the Swiss Alps with a mission to revolutionize the sensation of running. Their unique Cloudtec® system is based on a radical idea of soft landings followed by explosive take-offs, resulting in the feeling of running on clouds. This innovative system actively reacts to your individual running motion, with the cloud elements taking the first heavy blow off your landing and transitioning naturally to the forefoot, where the elements become firm for a stable and powerful push-off.
