Who Are On Cloudboom Strike 2 For?

The Cloudboom Strike 2 is a dedicated marathon and half-marathon race-day shoe for experienced runners chasing personal bests at genuinely fast paces. If you race on your forefoot or midfoot and want a propulsive, no-compromise super shoe, this is built for you — but it is not a daily trainer or a recovery shoe, and slower or heavier-footed runners will get less from its aggressive geometry.

Feelings and Experience

Underfoot the PEBA-based Helion HF foam feels lively and springy rather than pillowy, with the carbon Speedboard driving a quick, rolling toe-off that rewards a strong stride. Transitions are snappy once you're moving with intent, but the tall, narrow racing platform can feel tippy and unstable at easy jogging speeds — this shoe wants pace to come alive.

Performance Specs

Drop: On claims 5mm heel-to-toe offset, though caliper measurements run closer to 3mm — a low drop that suits forefoot strikers

Cushioning: High, PEBA-based Helion HF — a race-tuned stack, protective but not max-plush

Responsiveness: Very high — full-length carbon Speedboard plate paired with springy PEBA foam

Stability: Low — narrow, tall racing geometry with neutral support only

Pace: Optimal for 3:00–3:30 min/km (4:49–5:38 min/mile)

Best Distances and Maximum Speed

This shoe genuinely excels over the half marathon and full marathon, with the marathon as its sweet spot for runners holding a hard, sustained effort. Its technology works best at roughly 3:00 min/km (4:49 min/mile) and faster, where the plate and foam return the most energy.

Technologies and Materials

The midsole pairs On's PEBA-based Helion HF foam with CloudTec Sphere forefoot pods and a full-length carbon Speedboard plate. The standard upper is a light, net-like open-weave Lenoweave mesh (a sprayed LightSpray version is also offered). It weighs roughly 200 g in a men's US 9 — featherlight, though the minimal upper and racing stack favor performance over long-term durability.
