Our Verdict
HOKA Bondi 8
ASICS SONICBLAST 2
The ASICS SONICBLAST 2 is a better running shoe overall than the HOKA Bondi 8. It's substantially lighter, more cushioned, and livelier, making it better suited to long runs and faster sessions. Choose the cheaper Bondi 8 if you mostly do easy mileage and prioritize a broad, stable platform.
