dynamic rebound particles store and release energy

Run smooth. Feel faster. The Cloudsurfer Next adds forward roll to soft CloudTec Phase. So every run feels effortless. As your feet hit the ground, the CloudTec Phase midsole collapses in sequence, creating a smooth roll-through from heel to toe. When it's time for takeoff, bouncy Helion superfoam boosts you forward with a kick. Every step feels effortless, yet dynamic. The Cloudsurfer Next's updated forefoot rocker pushes power to the front. Built for daily running, it's light, cushioned and responsive. And feels fast too. Combined with Cloudsurfer cushioning for an effortless feeling, put simply, it makes faster running feel easier. Modeled on our top race-day shoes, the updated Cloudsurfer Next upper is engineered ultralight. Highly breathable, its woven mesh hugs your feet for a comfortable and secure ride. As you pick up pace, rubber pads on the outsole grip the road.
