Get your miles’ worth with On Running’s lightweight Cloudsurfer training and racing shoe. The Cloudsurfer is designed for those faster feeling days. Sometimes they’re training, and sometimes racing. Whenever the fast strikes you, you’ll find On Running’s patented CloudTec cushioning system alchemizing impact forces into forward motion. As a bonus, its adaptive platform improves balance and activates postural muscles. Inside the Cloudsurfer is just as comfortable as outside, with a memory foam heel collar that custom-forms to you and intelligent side stitching to make tongue drift a thing of the past. Light 3-D air mesh provides optimal air intake and cooling on even the hottest days. But it’s in the details that the Cloudsurfer shows its intelligent design. A nylon pull loop on the heel makes those triathlon transitions a breeze, an alternate pair of laces lets you customize your ride, and a reflective heel cap keeps you visible at morning or night. With its sleek, lightweight upper and responsive cushioning, On Running’s Cloudsurfer is the perfect multiuse shoe for racing and training.
