“White, dusty pink, orange and black. Came in from another runner. Scratches and scuffing on the pale parts of the sole grip, the black tread is still clear and grippy. Pink base of the cushioning is scuffed and rough along the edges, looks only. Grey marks and light dirt on the front and sides of the shoe, doesn't change how they run. Cleaned, original laces. A race day pair, ready for your next 10k, half or marathon.”

Expert summary
The On Cloudboom Echo 3 is engineered as a high-performance carbon-plated 'supershoe' with a responsive Pebax midsole and a propulsive ride, optimized for speed and race-day efforts. Expert reviews consistently highlight its snappy, forward-rolling sensation and energy return at fast paces, making it ideal for racing from 5K to marathon distances and for tempo/threshold workouts. The shoe's relatively firm and narrow platform, combined with a less plush midsole compared to competitors, makes it less suitable for daily training or recovery runs, where comfort and stability are prioritized. While the increased cushioning over previous versions improves its viability for longer efforts, some experts and users still find it less forgiving for full marathon distances, especially for those preferring maximal cushioning. The outsole and upper are designed for road use, offering little traction or protection for trails. User feedback and expert consensus indicate that the shoe feels awkward at slower paces and is best reserved for fast running, with some durability concerns noted in the outsole rubber.
Ideal as, Race-Day. Experienced runners or competitive athletes seeking a high-performance racing shoe for road events from 5K to marathon; best for those with efficient form who prefer a firmer, responsive ride and regularly train or race at fast paces; ideal for runners prioritizing breathability, sustainability, and a secure fit over maximal cushioning.
Pros
- Delivers a highly propulsive ride with a pronounced rocker and carbon plate, maximizing speed for race efforts
- Exceptional breathability thanks to a thin, engineered mesh upper with micro-ventilation, keeping feet cool even in hot conditions
- Improved fit and increased forefoot room compared to previous versions, reducing discomfort on longer runs
- Lightweight build for a plated racer, supporting fast turnover without feeling overly minimal or unstable
- Eco-conscious design with 46% bio-based materials and full recyclability
Cons
- Midsole cushioning is firmer and less plush than some competitors, which may not suit runners seeking maximum softness for the marathon distance
- Best suited for fast paces—feels awkward and less comfortable at slower speeds or during easy runs
