Why 310 km: the On Cloudboom Strike 2 runs PEBA superfoam built for race-day. PEBA loses its bounce before the outsole wears out, so its usable life is shorter than an EVA trainer's. This baseline reflects usable life for what the shoe is for, adjusted for foam and durability.

Expert summary
The On Cloudboom Strike 2 is On's next-generation carbon race shoe built for competitions up to the marathon. At 191g with a 5mm drop, it pairs the new CloudTec Sphere geometry with a curved carbon Speedboard sandwiched between dual-density Helion HF foam, now 15% lighter than before. This is a purpose-built racer aimed at runners chasing PBs over half and full marathon distances, with an emphasis on propulsion, energy return, and low weight. It runs fast and light, with a stiff plate driving forward momentum. Not a do-everything trainer, it is at its best on race day and fast tempo efforts.
Ideal as, Race-Day. Competitive road racers targeting half and full marathon PBs who want a light, stiff, carbon-plated shoe for race day and fast workouts, and already have separate trainers for daily miles.
Pros
- Very light at 191g
- Stiff carbon Speedboard for strong forward propulsion
- New CloudTec Sphere geometry for impact absorption and rebound
- Lighter, higher-energy-return Helion HF foam
- Co-developed with elite athletes for racing
Cons
- Race-focused with limited versatility
- Premium price at 250USD
