What's new with the Cloudswift? Well, almost everything. The new upper fuses supportive comfort with an unmistakably modern silhouette. And gliding over the concrete below your feet is the re-engineered bottom unit for softer landings and even more powerful take-offs. Hard surfaces require soft cushioning. Through its re-engineered bottom unit (featuring CloudTec® and dual-density Helion™ superfoam) the all-new Cloudswift softens the impact on the ground. The Speedboard® then injects your take-off with the stored energy from the landing. The all-new upper comes with its fair share of upgrades. The zonal knit material creates a comfortable sensation for many foot shapes. Slipping in really couldn't be more convenient. Once in, the 3D heel padding firmly holds your foot in place while you zigzag across the sidewalk.
