ASICS Megablast vs ASICS Sonicblast 2

ASICS Megablast

+ Praised

Springy and fast once the pace picks up; several reviewers find it flat at slow jogging speeds, and one finds the wide platform bulky.

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 Megablast

+ Praised

Deep, protective stack that holds up on long runs, though one reviewer calls the foam firm rather than soft.

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 Megablast

± Divisive

Light and breathable, but the most common fit complaint: a shallow, tapered toe box, a stiff toe piece, lace bite and a scratchy liner for some.

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 Megablast

+ Praised

Long-term testers report little foam or outsole wear at 100 to 250 miles and expect it to last well past 600; one lab test flags a weak toe box.

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 Megablast

+ Praised

Sticky on dry and wet pavement; the exposed foam makes it a poor choice for gravel or trails.

ASICS Sonicblast 2

+ Praised

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

ASICS Megablast

+ Praised

Most reviewers find the wide base and firmer foam surprisingly stable for the height; two find the tall platform wobbly, especially at the heel.

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 Megablast

− Criticised

The most common complaint: expensive for an unplated trainer. A few long-term testers say the durability earns back the price.

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.
