Our Verdict

HOKA Skyward X

New Balance FuelCell SuperComp Trainer v3

The New Balance FuelCell SuperComp Trainer v3 and the HOKA Skyward X are two plated trainers that offer distinctly different experiences underfoot. The SuperComp Trainer v3 strikes a number of compromises to create a smooth, consistent ride. Its midsole is not too soft or too firm, and the very reasonable width-to-stack ratio makes the New Balance shoe very stable. The Skyward X, on the other hand, throws caution to the wind and embraces the wild bounciness that characterised previous versions of the SuperComp Trainer v3. The HOKA shoe has much better energy return and cushioning than the SC Trainer v3, but it's considerably less stable: although the Skyward X sits 12 mm higher, it has a similarly sized platform, which can feel like running on stilts compared to the more grounded New Balance.
