Our Verdict

Brooks Adrenaline GTS 25

ASICS GEL-KAYANO 33

The ASICS GEL-KAYANO 33 and Brooks Adrenaline GTS 25 are both support shoes, but they approach the job differently. The ASICS prioritizes cushioning, delivering a softer, more protective ride that's better suited to longer runs. The Brooks, meanwhile, leans further into stability, pairing a lighter build with a higher drop that makes it particularly well-suited to heel strikers. Neither shoe is especially lively underfoot, but if comfort and impact protection are your priorities, the ASICS is the better choice. If you want a more supportive shoe with a firmer, more structured ride, the Brooks is the shoe for you.
