Overview The Cloudswift 4 is On's urban-road trainer — cut for the city runner who deals with curbs, concrete, and short distances. Dual-density Helion gives a propulsive push-off while the 10 mm drop favours heel strikers; a knit upper and refined silhouette lean into the urban aesthetic. Reviewers note the shoe is more commute-and-short-runs than speedwork. Cloudswift 4, urban road trainer at 10 mm drop, dual-density Helion. City concrete, commuter miles, short-to-medium distances. Details Best for: City running on hard concrete Commute and mixed run-walk days Heel strikers on short-to-medium distances Runners who want an On trainer that wears as well as it runs Specs: Category: Urban road Stack: 32.7 mm heel / 22.3 mm forefoot (lab-measured where available) Drop: 10 mm Weight: ~291 g (men's US 9) Midsole foam: Dual-density Helion (soft top layer, denser base) Plate: Speedboard (nylon blend) Outsole: Rubber-covered CloudTec with urban-oriented tread Upper: Breathable knit mesh Colourway: Alloy / Lime, White / White, Black / Eclipse Sizing: 8 / 8.5 / 9 / 9.5 / 10 / 10.5 / 11 / 11.5 / 12 Materials & Care Designed in Zurich. Brush off dirt and debris after each run. Remove laces and insoles; hand wash uppers with cold water and mild detergent. Do not machine wash, tumble dry, bleach or dry clean.
