Our Verdict
Saucony Endorphin Speed 4
HOKA Mach X 2
The Saucony Endorphin Speed 4 and the HOKA Mach X 2 are both versatile super trainers, but each excels in different scenarios. The Saucony is lighter and more stable and offers a snappier, more responsive feel. In contrast, the HOKA is more heavily cushioned and plush. While both shoes are versatile enough for training and some racing, the Saucony shines brightest in shorter events, whereas the HOKA is the preferred option for those prioritizing cushioning and comfort over extended distances.
