Our Verdict
Saucony Endorphin Pro 5
Saucony Endorphin Azura
The Saucony Endorphin Pro 5 and Saucony Endorphin Azura serve different roles despite both being performance-focused shoes. The Pro 5 is considerably lighter and uses a carbon plate, making it the more race-focused option. The Azura is unplated and more cushioned, making it better suited to daily training and longer workouts where outright racing performance is less important.
