The On Running Cloudswift 3 in black is ideal for urban running and daily commuting. It offers a softer ride on hard surfaces and a zoned knit upper that adapts to different foot shapes. The CloudTec® midsole with a double layer of Helion™ superfoam absorbs shock and the Speedboard® returns energy to the rebound. The sock-like design, along with 3D heel cushioning, keeps your foot firmly in place, and its 251g weight provides agility in the city.
