Cloudswift 4

Daily Trainer2025-03-13 · JP · ReleaseChecked 2026-08-17

Cloudswift 4 is On’s fourth-generation trainer for everyday runs on hard city pavement. A soft Helion top layer sits over denser foam within CloudTec, while an injection-molded nylon-blend Speedboard and rocker shape guide landing-to-toe-off transitions. A one-piece knit upper, perforated toe box, and updated midfoot cage secure the foot; a rubber outsole with an enhanced lug pattern adds road traction.
