Contrary to popular belief, you can't run on a cloud. It's just water vapor, and you'll fall right through. If you want lightweight comfort, you can stay ground level with some On Men's Cloud Running Shoes. Zero-Gravity foam and CloudTec® in the outsole gives you soft, cushioned landings for an even smoother ride than ever before. Reshaped Cloud elements deliver great performance and grip, while the molded heel provides a snug, secure fit. The Speedboard transforms energy generated upon landing into forward motion. The signature speed-lacing system lets your feet slip in and out with ease, yet keeps the shoes firmly in place on the move for performing all day, every day.
