What Our Gearhead® Experts Are Saying: "I’ve been using the Cloudsurfer as my daily trainer and it nails that soft-yet-smooth feel. The cushioning absorbs shock without slowing me down, and the ride feels really fluid from heel to toe. Great for easy miles, long days, and even recovery runs."When comfort and performance finally sync, you get something like the Cloudsurfer. This daily trainer is built around On’s newest CloudTec Phase™ technology—a midsole that compresses in a precise sequence with each stride to deliver softer landings and seamless transitions. The result? A smoother, more natural-feeling run that feels as good at mile five as it does at mile one. The reengineered midsole eliminates the traditional Speedboard to reduce stiffness and keep the ride flowing freely, while the lightweight mesh upper offers breathable support without the bulk. The upper is crafted from 100% recycled polyester for a reduced environmental footprint. Whether you're easing back into a training plan or logging consistent base miles, the Cloudsurfer helps you stay light on your feet and focused on the road ahead.
