On Cloudflyer 5

Who Are On Cloudflyer 5 For?

The Cloudflyer 5 is a supportive daily trainer for runners who want a stable, cushioned base for everyday miles and steadier tempo efforts. It suits mild overpronators and anyone who values a planted, secure ride over a lively racing feel. If you're chasing PRs or want a plush recovery-day cloud, look elsewhere — this shoe is built for control and consistency.

Feelings and Experience

Underfoot the Helion foam feels firm and settled rather than pillowy, giving a grounded, dependable ride that holds its shape as you fatigue. The Speedboard adds a gentle snap through toe-off, so pace pickups feel willing without ever turning aggressive. The trade-off is that it's not especially soft or bouncy for slow jogs — some runners find it a touch firm until it warms up.

Performance Specs

• Drop: moderate-to-high heel-to-toe offset (the height difference between heel and toe) — favors heel strikers and a smooth, protective rollthrough

• Cushioning: high, Helion superfoam — generous protection without going max-stack plush

• Responsiveness: above-average — driven by the Helion foam plus the composite Speedboard, not a carbon race plate

• Stability: high — a wide platform with structured stability support for mild pronation

• Pace: Optimal for 5:00–6:00 min/km (8:00–9:40 min/mile) — its daily-training comfort zone

Best Distances and Maximum Speed

The Cloudflyer 5 shines over 10K and the half marathon, with the half as its sweet spot for supported, sustained efforts. It's equally happy on easy and long training runs. Push it and it works best down to roughly 4:45–5:15 min/km (7:38–8:27 min/mile); beyond that the firmish ride and stability structure hold it back.

Technologies and Materials

The midsole uses On's Helion foam paired with the Speedboard, a composite (non-carbon) plate that guides transition. An engineered mesh upper adds structured lockdown that supports the stability build, and On's CloudTec pods form the outsole. Specific weight, stack, and drop figures weren't provided, so treat the fit as supportive but slightly heavier than a pure speed shoe.
