Cloudboom Echo 3
Cloudboom Echo 3 is a lightweight marathon and road-racing shoe shaped by elite-athlete feedback. It pairs CloudTec with Helion HF hyperfoam made with 46% bio-based material, while a rocker-shaped full-carbon Speedboard balances impact protection with energy return. A thin, breathable one-piece upper reduces weight, and silicone details on the laces and sockliner help maintain a secure race fit.
