ASICS Gel Kayano 33 vs Brooks Adrenaline GTS 25

ASICS Gel Kayano 33

± Divisive

Smooth, plush and stable at easy paces, but reviewers split on whether the new dual-foam setup is an improvement: some find it softer and more natural, others find it firm, flat and forgettable.

Brooks Adrenaline GTS 25

± Divisive

Softer DNA Loft v3 and a lower 10 mm drop smooth the heel transition and make easy miles more comfortable, but the ride is still firm and short on energy return, and some testers find it dull.

ASICS Gel Kayano 33

+ Praised

Plush, protective cushioning that holds up over long runs without turning mushy, especially in the heel.

Brooks Adrenaline GTS 25

+ Praised

More foam in the heel and forefoot takes the edge off landings and suits daily mileage, though lab tests call it average and the forefoot firms up over longer runs.

ASICS Gel Kayano 33

+ Praised

Comfortable, secure and well padded, with a roomy forefoot for most; the main complaint is a laterally tapered toe box that pinches the outer toes and a warm, heavily padded rear.

Brooks Adrenaline GTS 25

± Divisive

A roomier forefoot and soft mesh improve comfort for many, but the tapered toe box, thick warm upper and heavily padded heel collar divide testers.

ASICS Gel Kayano 33

+ Praised

Thick outsole rubber, a durable dual-layer mesh and little wear in testing point to a long life.

Brooks Adrenaline GTS 25

+ Praised

Reviewers generally expect a long-lasting daily trainer, with strong outsole wear scores, though one long-term tester saw average wear and early foam compression.

ASICS Gel Kayano 33

+ Praised

Hybrid ASICSGRIP is excellent on wet and dry pavement, with one lab result among the best tested; loose gravel and slick stone are weaker.

Brooks Adrenaline GTS 25

+ Praised

Grippy rubber handles wet roads and light paths well, with only the exposed foam limiting off-road use.

ASICS Gel Kayano 33

+ Praised

A broad, rigid platform and the new FluidSupport system give confident, unintrusive guidance, though one reviewer finds the medial midfoot support thin for a stability shoe.

Brooks Adrenaline GTS 25

+ Praised

GuideRails and a broad, flared base give noticeable but unobtrusive medial support that holds up when form fades.

ASICS Gel Kayano 33

± Divisive

Some say it earns its $170 as a premium stability trainer, while others argue the Kayano 32 on sale or lighter rivals offer more for less.

Brooks Adrenaline GTS 25

± Divisive

At $155 it is fairly priced for a durable stability trainer, though some reviewers say lighter, livelier rivals offer more for similar money.
