Growing up in the Swiss Alps, the On team learned a thing or two about running in the mountains. When we set out to design the perfect trail running shoe, we remembered what is important: a shoe so light and fast that you can reach the peak in time to watch the sunrise. Reliable grip for when a thunderstorm catches you by surprise. And clever cushioning to save your legs when you are flying back down to reach the valley before it gets dark. Introducing the On Cloudventure – The ultimate trail running shoes.
