Our Verdict

HOKA Mach X 2

Saucony Endorphin Speed 5

The Saucony Endorphin Speed 5 and the HOKA Mach X 2 both target the speed training space but take very different approaches. The Saucony leans into a more traditional feel: moderate stack height, nylon plate, and a firmer, snappier ride that offers a strong sense of ground contact. It's ideal for efficient runners with a higher cadence who prefer a bouncy midsole that rewards quick turnover and precision. The HOKA, on the other hand, is much higher stacked and more cushioned, with a softer, more forgiving midsole and a nylon plate embedded in a thicker geometry. The midsole isn't as energetic as the Saucony but delivers a smooth, propulsive, and cushioned experience, especially over longer efforts. Both shoes weigh about the same, but the ride character couldn't be more different.
