You'll find these extremely comfortable for wearing all day long for general use. Perfect for walking around in doing day to day activities. They are very lightweight though they won’t keep you very warm on a cold day as the upper material is quite thin.

Fit: Fits true to size, no need to size up.

Category: Neutral. 

Best for: All day, urban exploration, travel.

Cushion level: Low. 

Nothing to stop you using them for running, but may find they don’t offer enough protection or be durable enough long term if you did so. The On brand's fan favorite re-engineered with 44% recycled content, improved fit, and more comfort than any other version of the Cloud.

Technology

CloudTec®. Zero-Gravity foam and CloudTec® in the outsole provide soft, cushioned landings. Reshaped Cloud elements deliver superior 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 foot slip in and out with ease, yet keeps the shoe firmly in place on the move.

Materials

Breathable mesh. The Cloud is famous for its unmatched step-in feel, thanks to the blend of soft-touch fabrics used in the upper. The breathable, antimicrobial mesh provides stay-fresh comfort, while soft, no-sew taped reinforcements across the shoe and toe cap support the perfect fit.
