Our Verdict
ASICS MEGABLAST
Saucony Endorphin Azura
The ASICS MEGABLAST and Saucony Endorphin Azura are versatile, unplated performance trainers with very different rides. The MEGABLAST is lighter, more cushioned, and bouncier, making it the better option if you want a softer, more energetic ride. The Azura is more stable and significantly snappier, with a firmer, more rocker-biased ride that provides greater leverage through toe-off. Get the MEGABLAST for bounce and protection; get the Azura for a more stable, geometry-led ride.
