Our Verdict
ASICS SUPERBLAST 2
Dynafish Xiaonian
The Dynafish Xiaonian is a better running shoe than the ASICS SUPERBLAST 2. It’s significantly lighter, has much better energy return, and is a bit more cushioned, so it takes less effort to run in, better protects your legs from impact, and can handle everything from faster sessions to long runs and marathon racing more comfortably. The ASICS is slightly more stable and still a great option for regular miles, but unless that extra stability is important to you, the Dynafish is the better shoe overall.
