The ASICS Megablast is one of the brand’s most exciting launches for 2025, dropping September 1st at $225. But what exactly is this shoe, how does it fit into the ASICS Blast lineup, and is it worth the premium price tag? After putting it through easy runs, marathon pace sessions, tempo efforts, and a long run, here’s my full breakdown.
Stats & Features
Price: $225 (US launch, UK pricing TBD)
Weight: ~250g (UK 9.5)
Stack Height: 45mm heel
Foam: New FlyteFoam Turbo Square (aliphatic TPU) – 33% bouncier, 10% softer than previous Turbo
Plate: None
Upper: Engineered woven mesh with pull tab and race-style laces
Outsole: ASICS Grip rubber
Fit: True to size
On paper, the Megablast is light, cushioned, and versatile. The woven mesh upper surprised me with its comfort and lockdown, and while I’m undecided on the colourway, the build feels premium.
Where It Fits in the Blast Range
The ASICS Blast lineup is now stacked:
Novablast 5 → everyday trainer
Sonicblast → plated super trainer
Superblast 2 → long-run machine / marathon racer
Megablast → the all-in-one option
Think of the Megablast as the “one shoe to rule them all” (yes, a Lord of the Rings reference) — blending elements of the Nova, Sonic, and Superblast into one versatile package. It has no plate, but it’s designed to handle everything from easy mileage to race day.
Performance Review
Over a week of testing, including a long run, the Megablast impressed me at all paces:
Easy pace (8:30/mi / ~5:20/km): Surprisingly smooth, stable thanks to the wide base, and not clunky like the Superblast can feel at slower speeds.
Marathon pace (~8:00/mi / ~5:00/km): The shoe really comes alive — light, bouncy, and efficient, with a feel similar to the Superblast but a touch more effortless.
Tempo pace: Despite the big stack, the foam feels energetic and responsive, making faster efforts fun and snappy.
Crucially, the Megablast handled all three paces well — versatility is its biggest strength.
Megablast vs Superblast 2
The Superblast 2 has long been my go-to marathon training shoe: unbeatable for long runs and holding pace, but clunky at easy effort.The Megablast takes all the best parts of the Superblast (comfort, long-run feel, pace holding) and improves on the weaker areas (easier at slow paces, lighter, bouncier). It’s essentially a more complete version — though notably without a plate.
Price & Value
Here’s the sticking point: at $225+, this is an expensive non-plated shoe. The Superblast 2 already sits at £195 / $200, and the Megablast will be pricier.
Can I justify it? Honestly, yes — but only if you want a one-shoe rotation. If you like having multiple shoes for different sessions, the Megablast might not be essential. But if you want one trainer that covers everything — daily runs, long runs, tempos, and even race day — it could save you buying two or three pairs.
Conclusion
The ASICS Megablast surprised me. The new FlyteFoam Turbo Square foam is a big upgrade: softer, bouncier, yet stable enough to handle easy mileage. It’s versatile, fun, and could easily serve as a do-it-all shoe for marathon training.
