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
- Not suited to easy or recovery days
