ASICS Gel Kayano 33 vs ASICS Sonicblast 2

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.

ASICS Sonicblast 2

+ Praised

The redesigned shoe is more fluid and lively at marathon and tempo efforts, though its stiff midfoot and less energetic heel can feel awkward at easy paces.

ASICS Gel Kayano 33

+ Praised

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

ASICS Sonicblast 2

± Divisive

The high stack protects well on long runs, but its firmer feel is not to every runner’s taste and the forefoot bounce is more noticeable than the heel.

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.

ASICS Sonicblast 2

+ Praised

The lighter mesh is breathable and generally secure with useful toe volume, though some find the racer-focused upper less plush and the toe shape tapered.

ASICS Gel Kayano 33

+ Praised

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

ASICS Sonicblast 2

+ Praised

Early reports and lab testing suggest the outsole holds up well, while the thin toe mesh is a possible weak point.

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.

ASICS Sonicblast 2

+ Praised

Lab results are excellent and runners report dependable road traction, with no major grip concerns in early 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.

ASICS Sonicblast 2

± Divisive

Several reviewers find the broad geometry and firmer foam unusually composed for a tall trainer, while others caution it is still a neutral shoe and not the most stable option.

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.

ASICS Sonicblast 2

± Divisive

Some consider the price reasonable for a versatile plated trainer, while others question the premium given the ride and alternatives in the range.
