On Cloudswift 4

Who Are On Cloudswift 4 For?

The Cloudswift 4 is built for recreational runners who want one versatile daily trainer for city miles and the occasional pickup in pace. It suits neutral runners logging steady mileage and light tempo work, not those chasing marathon PRs or needing plush, high-stack recovery cushioning. Beginners will find it accessible, though speed-focused racers will want something lighter and more aggressive.

Feelings and Experience

Underfoot the Helion foam feels firm and controlled rather than soft or springy — energetic when you push the pace, a touch dead if you plod. The CloudTec pods compress on landing and give a distinct urban-firm feel with decent ground connection, and the Speedboard shank smooths the roll from heel to toe. On rougher paths the pod geometry can feel slightly less planted, but on pavement the transition is clean.

Performance Specs

• Drop: 7mm heel-to-toe offset — a moderate ramp that balances heel comfort with forefoot feel

• Cushioning: Moderate, Helion superfoam with a CloudTec Phase midsole (roughly 35mm stack) — protective without being maximalist

• Responsiveness: Above-average, driven by the composite Speedboard shank rather than a carbon racing plate

• Stability: Neutral, typical daily-trainer stability from a reasonably wide base and no medial posting

• Pace: Optimal for 4:30–5:15 min/km (7:15–8:25 min/mile)

Best Distances and Maximum Speed

The Cloudswift 4 excels at 5K, 10K, and half marathon efforts, with steady 10K training runs as its sweet spot. Its fastest effective zone is around 4:15–4:45 min/km (6:50–7:35 min/mile), where the Speedboard snaps through transitions. Push much quicker and the firm ride starts asking for a lighter racer.

Technologies and Materials

The midsole pairs Helion foam with On's CloudTec Phase pod geometry and an embedded composite Speedboard for propulsion. The engineered mesh upper leans urban and durable, and the rubberized pods handle city pavement well, though the exposed CloudTec channels can trap small stones on trails.
