New On Cloudflow 4 shoes, lightweight, responsive and definitely fast. You lead the race or training, with a shoe that gives speed to allɜ. You wanted speed, so we added a nylon-blend Speedboard® that's stiffer, stronger, and lighter than its predecessor. Now the momentum feels even more powerful to catapult you straight to a new PR. Try it to believe it. The ultra-lightweight technical fabric upper takes its lead from our fastest shoe ever, the Cloudboom Echo 3. The result?
