The CLOUD 6 W from On Running is a women&#039s running shoe that won&#039t go unnoticed with its inimitably designed sole.This new version is a huge success thanks to its featherweight, comfort and minimal impact on the environment, as it has been redesigned using recycled and bio-attributed materials. Featuring a breathable upper, it combines CloudTec® technology in the Zero-Gravity foam, which provides softer cushioning with every stride, with enhanced Speedboard®, which transforms energy into movement, and a quick release for maximum efficiency.
