The On Cloudboom Strike LS is On's lightest, fastest, and most advanced marathon racing shoe. It features a unique laceless LightSpray upper for a secure, smooth fit, and a Helion HF (PEBA-based) midsole with a carbon Speedboard for a propulsive, bouncy ride. Reviewers praise its incredibly low weight (around 170-192g), speed, and impressive durability for a racer, making it ideal for racing from 5K to marathon, tempo runs, and track workouts. However, its high $330 price point makes it a niche product, mainly for avid enthusiasts.
Highlights
- Incredibly lightweight construction (approximately 170-192g)
- Fast, smooth, and highly responsive ride with strong propulsion
- Secure, comfortable fit with a smooth, non-irritating laceless upper
- Durable upper and midsole for a lightweight racing shoe
- Versatile across fast paces and race distances from 5K to marathon
Considerations
- Laceless upper may create pressure across the widest part of the foot
- One-piece construction might not accommodate wider foot shapes well
- Midsole ride leans slightly firm, which may not suit all marathon preferences
- Limited fit customization due to the fixed, non-adjustable upper design
- Optimized for fast efforts and racing rather than easy or recovery runs
