Our Verdict
Saucony Endorphin Azura
Dynafish Xiaonian
The Dynafish Xiaonian and Saucony Endorphin Azura are unplated performance trainers with different approaches to propulsion. The Dynafish is much lighter and more cushioned, with a more aggressive rocker that provides more assistance through the stride. The Azura has a more rigid forefoot that provides greater leverage through toe-off, making it the better option if you prefer snap over a heavily rocker-driven ride.
