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 has a more even cushioning profile and is more forgiving in the heel, especially at higher force levels, making it a more appealing option for heel strikers. The Diadora has a softer step-in feel and provides better cushioning at lower force levels, but firms up faster, resulting in a stable ride for all, but a potentially harsher feel at fast paces for larger runners.
