ASICS Sonicblast 2 vs ASICS Superblast 3

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 Superblast 3

+ Praised

Softer and bouncier than the Superblast 2 thanks to FF Leap, with a smooth, lively roll that works from easy miles to marathon pace; a few find it too big and soft for sharp speedwork.

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 Superblast 3

+ Praised

Exceptional, deeply protective cushioning that stays plush deep into long runs, with one of the most protective forefeet in the lab.

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 Superblast 3

± Divisive

The wider toe box fixes the cramped fit of the Superblast 2 and the woven mesh is comfortable, but the stiffness and a snug arch divide testers, and ventilation is only moderate.

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 Superblast 3

± Divisive

Most find the midsole and rubber long-lasting, but the softer outsole rubber and large exposed foam patches show early wear in some tests.

ASICS Sonicblast 2

+ Praised

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

ASICS Superblast 3

+ Praised

Outstanding road grip in dry and wet conditions, with lab traction the best tested at the time; loose gravel is its limit.

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 Superblast 3

± Divisive

The wide base and firmer carrier foam keep it manageable for its height, but the soft FF Leap makes it noticeably less planted than the Superblast 2, and the forefoot flare divides reviewers.

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.

ASICS Superblast 3

− Criticised

At $210 it is hard to justify for most runners, especially with cheaper super trainers and the Superblast 2 on discount offering most of the experience.
