Buy Superblast 2 on sale for long runs and steady daily mileage if you want a stable, durable, firm-ish super-trainer; skip it at full $200 retail when Evo SL covers most of the same job for less EVO SLs now my all-time favourite daily trainer, not even close.

Full breakdown

ASICS Superblast 2 is the unplated super-trainer that pairs a tall FF Turbo Plus midsole over a thin FF Blast Plus base, a wide stable platform, and a non-stretch engineered mesh upper. Long-mileage owners describe it as a reliable long-run cruiser rather than a magic-bouncy shoe, with one 600-mile owner calling it the best daily trainer he has owned without exaggeration, this has been the best daily trainer I’ve owned. Buy it for stable high-stack daily and long-run mileage, not for slow recovery jogs where the firmness reads clunky.

FAQ

How should Superblast 2 fit, and should I size up or down?

Size true to size — the mesh upper has zero give, and undersizing is a documented mistake on this shoe. A first-run owner with wide feet was direct that the mesh has no stretch versus a Kayano or Vomero Plus and you must not undersize or you will suffer the mesh upper has zero give/stretch, you must NOT undersize the superblast 2 or you will suffer. Wide-foot buyers should consider trying in-store; the platform is wide but the upper itself is fitted.

Is the Superblast 2 actually fun to run in, or just hyped?

It is reliable rather than magical, and owners openly call out the gap between hype and feel. The 512-mile reviewer called it solid but kind of overhyped and noted it works best when the bigger/taller crowd loads the foam kind of overhyped but solid long distance trainer, more popular with the bigger/taller crowd to get the most out of the foam, and the first-impressions thread says you really feel the bounce only at 4:30/km or faster. Buy it for fast aerobic and long-run pace ranges, not slow recovery jogs.

How long does Superblast 2 last in real mileage?

Plan on 500-700 miles before noticeable foam fade, which is excellent for a super-trainer. The 600-mile owner reported the outsole worn at forefoot/heel but the foam still bouncy and ride consistent, while a separate 1,800km owner saw flatness creep in around 700-800km versus 800-900km on the OG Superblast SB2 at 700+km they feel like they are flattening out. Buy a backup pair when ASICS purges stock for the next version.

Should I pick Superblast 2 or the new Megablast?

Pick Megablast if the OG Superblast was your sweet spot; pick SB2 if you want stable long-run miles at a sale price. An OG-Superblast loyalist who ran nearly 600 miles in V1 was disappointed by SB2 and called the Megablast the SB2 he was waiting for — closer to the OG feel and a bit lighter the Megablast is much closer in feel to the OG Superblast except a little lighter. If you cannot find Megablast or do not want to pay the new price, SB2 on discount remains a strong daily-and-long-run choice.
