Our Verdict

HOKA Skyward X

HOKA Mach X 2

The HOKA Skyward X and the HOKA Mach X 2 both sit in the high-cushion performance trainer category, but their execution differs. The Skyward X prioritizes plush comfort with an extreme stack height and carbon plate, making it feel more like a max-cushioned cruiser than a performance shoe. The Mach X 2, on the other hand, refines the formula of its predecessor, offering an even more cushioned ride but with better energy return and a more natural transition. Despite its slightly increased cushioning, the Mach X 2 remains lighter and more stable than the Skyward X, making it a stronger choice for those who want a dynamic yet comfortable daily trainer. The Skyward X works best for easy runs where protection is key, while the Mach X 2 offers more versatility across different paces and workouts.
