Our Verdict

HOKA Rocket X 3

Diadora Gara Carbon 2

The Hoka Rocket X 3 and Diadora Gara Carbon 2 are two plated super shoes with similar performance profiles, offering a balanced blend of cushioning, stability, and speed without going over the top in softness or aggressiveness. Both weigh about the same and deliver comparable energy return and underfoot protection, making them solid options for long-distance racing. The main difference lies in ride character and fit: the Rocket X 3 absorbs more impact, especially in the heel, and feels a touch plusher overall, while the Gara Carbon is slightly firmer at lower forces. Diadora's tighter fit and premium upper materials create a more race-day–focused sensation, while Hoka's more forgiving upper makes it a better choice for runners who want more room without sacrificing performance.
