The On Cloudswift 4 AD "Black/Rock" Women's Shoe's snug bootie construction is updated with a single-piece knitted upper for maximum airflow. The perforated toe box further boosts breathability.&nbsp;For a cushioned yet energetic ride, the midsole's top layer is made with soft Helion™ superfoam, while denser foam on the bottom provides a more propulsive push-off.&nbsp;We updated the design and fit of the shoe's iconic cage construction for better midfoot lockdown. Plus, it's now finished with a new knit material for a more modern look. <ul> <li>Weight: 248g</li> <li>New dual-density Helion™ superfoam midsole for soft landings</li> <li>Breathable one-piece upper with perforated toe box</li> <li>Updated cage construction for better midfoot lockdown</li> <li>Nylon-blend Speedboard® for a responsive ride</li> <li>Fresh aesthetic and comfortable fit</li> <li>Rockered geometry for a forward-rolling sensation</li> <li>Responsive daily shoe for road and city running</li> <li>Versatile style for before, during and after a run</li> </ul>
