On Cloudsurfer 2

Who Are On Cloudsurfer 2 For?

The Cloudsurfer 2 suits recreational runners who want one shoe for daily mileage that can also pick up the pace on tempo days. It's aimed at neutral runners chasing smooth, versatile training rather than pure race-day speed or plush recovery-day comfort — if you want a soft marathon cruiser or maximum plushness, look elsewhere.

Feelings and Experience

Underfoot the Helion superfoam feels lively and moderately soft, with a springy roll-through as the CloudTec Phase "clouds" collapse in sequence. Transitions are smooth and the ride wakes up nicely when you lean into faster efforts. The trade-off: that collapsing-cloud geometry feels a touch less planted at very slow, casual paces, so it rewards runners who keep some rhythm.

Performance Specs

• Drop: 7mm heel-to-toe offset — a moderate slope that keeps you slightly forward without straining the calves

• Cushioning: moderate, Helion superfoam — enough for daily miles without going full max-stack

• Responsiveness: above average — energy comes from the resilient Helion foam, not a plate

• Stability: medium — a neutral platform that stays honest at pace but isn't a guidance shoe

• Pace: Optimal for 5:00–5:45 min/km (8:03–9:15 min/mile) — comfortable uptempo training zone

Best Distances and Maximum Speed

This is a genuine 10K-to-half-marathon shoe, with the sweet spot around fast 10K efforts and steady half-marathon tempo. It works best when you push toward roughly 4:45–5:15 min/km (7:38–8:27 min/mile), where the foam rebounds most eagerly. Beyond half-marathon distance the moderate stack starts to feel like enough rather than plenty.

Technologies and Materials

The midsole is On's Helion superfoam shaped into the CloudTec Phase geometry, with no plate — rebound is foam-driven. Stack sits around 34mm heel and 27mm forefoot, and a breathable engineered mesh upper wraps the foot. Exact weight wasn't provided, so try before committing if fit precision matters to you.
