Our Verdict

Saucony Endorphin Pro 4

ASICS MEGABLAST

The Saucony Endorphin Pro 4 and ASICS MEGABLAST both sit in the high-stack performance space, but they serve different roles. The Endorphin Pro 4 is a plated racing shoe that is lighter, snappier, and tuned for speed, making it a great choice for workouts and race day. The MEGABLAST, while unplated, has an even higher stack height and manages to feel impressively bouncy for a training shoe, though not quite as snappy as the Saucony. It is far more protective and forgiving, with cushioning that makes it suitable for everyday mileage and long runs. While the Saucony is the sharper tool for races, the ASICS doubles as both a versatile trainer and a potential racing option for amateur runners who prefer durability and comfort over top efficiency.
