Max Cushion2021-08-05 · JP · ReleaseChecked 2026-08-15

Cloudstratus 2 is a cushioned road shoe for distances from 5K to the marathon. Its second generation reworks the bottom unit, extending two CloudTec® layers through the forefoot and pairing Helion™ superfoam with a rocker-shaped polypropylene Speedboard® for protection and push-off. A wider forefoot, improved heel hold and star lacing support long-distance fit, while a rubber outsole adds grip and durability.
