Our Verdict

Saucony Endorphin Pro 4

Diadora Gara Carbon 2

The Saucony Endorphin Pro 4 and Diadora Gara Carbon 2 are two of the more stable super shoes on the market, thanks to their wide underfoot platforms, but they cater to different racing styles. The Endorphin Pro 4 is the more stable of the two overall, with its firmer foam delivering a solid base and a snappy toe-off that's especially well-suited for runners with a high cadence, making it a strong choice for shorter efforts. The Gara Carbon 2, on the other hand, takes a more balanced and forgiving approach: it's softer and significantly more cushioned, making it suitable for longer distances like the marathon.
