The ASICS Megablast is the new kid on the block, but it’s not shy about making an entrance. Sitting in the ASICS lineup as a max-cushioned daily trainer, it’s built to handle just about everything: long runs, easy days, and even faster paces when you’re feeling ambitious. Bonus: it’s the lightest shoe in the entire ASICS Blast lineup, which makes its versatility even more impressive.
The star here is the FF TURBO² midsole foam, ASICS’ bounciest and most energetic compound to date. It’s not just soft underfoot; it’s resilient, meaning the cushioning lasts mile after mile without giving up its pep. Combined with a thinner, lighter, and more breathable upper than what you’ll find on the Superblast, the Megablast feels lively yet comfortable, like max cushion without the marshmallow mush.
Why does max cushion plus responsiveness matter? Because most runners (especially those who want comfort without sacrificing fun) don’t just need shock absorption for their joints; they also need a shoe that helps return some of that energy with every step. The Megablast delivers both, giving you protection for long hauls and a bounce that keeps your stride from feeling sluggish. In other words: it’s kind to your knees and your motivation.

Design & Fit
The ASICS Megablast may be a max-cushioned workhorse, but its upper shows a clear nod to racing shoes. The engineered mesh is super light, highly breathable, and gives you that barely-there feel that keeps your feet from overheating on longer miles. Slip it on and you’ll notice the fit is snug and streamlined, with just enough room in the forefoot to let your toes spread out without feeling like they’re at a yoga retreat.
Sizing feels true, but here’s the catch: it leans on the narrow side. If you’ve got wide feet, you might feel like you’re squeezing into skinny jeans—possible, but not exactly comfortable. For most, though, the heel counter and padded collar nail the fit, offering that “locked-in but not locked-down” balance you’d expect from ASICS’ most popular daily trainers.
The gusseted tongue does its job quietly, keeping everything secure without creating hot spots or pressure points. And while the upper feels like a racer, the platform underneath is anything but flimsy: the wide base provides stability that gives you confidence at any pace. It’s like strapping a race car body onto a sturdy SUV frame—sleek on top, steady underneath.
Cushioning & Ride Quality
If there’s one reason the ASICS Megablast stands out, it’s the FF TURBO² midsole foam. This is ASICS’ bounciest, most energetic foam yet, and it’s better than its predecessor in every way—lighter, softer, and more resilient. You get the plush comfort of a max-cushioned shoe, but with a lively kick that doesn’t fade after a few runs.
On the road, the Megablast feels at its best during long runs and faster paces. It’s cushioned enough to keep your legs fresh, but snappy enough to make tempo miles feel less like work and more like play. Compared to the Superblast, it runs a touch softer and lighter (7.7 oz only for men & women), but not in the “sink-in” way—this foam bounces right back, giving you a responsive toe-off that keeps your stride moving forward.
The curved sole design helps smooth out transitions, making each step feel fluid and efficient. It’s that little bit of rocker that keeps you rolling, whether you’re cruising through easy miles or picking things up for a workout.
In many ways, the Megablast feels like the middle ground between the Superblast and Novablast—capable of doing it all, from recovery runs to tempos. It’s a rare mix: max cushioning that doesn’t slow you down, and responsiveness that doesn’t beat you up. Or put simply, it’s the kind of shoe that makes long miles feel shorter.
Performance on the Run
The ASICS Megablast plays nice no matter the pace. On easy runs, it feels smooth and cushioned, almost like it’s encouraging you to relax and enjoy the scenery. But pick up the tempo, and the shoe comes alive—suddenly that bounce in the FF TURBO² foam makes it easy to settle into faster paces without much extra effort. Long steady runs and tempo sessions are where it really shines, giving you both comfort and efficiency mile after mile.
That said, with its 45/37 mm stack height (8 mm drop) and wide platform, the Megablast isn’t trying to be your next racing shoe. It’s stable and protective, but some runners may find it a bit bulky if they’re chasing top-end speed. Think of it as the dependable training partner who can keep up when you push the pace but won’t exactly break the tape on race day.
For high-mileage runners, the soft yet resilient midsole offers excellent joint protection, making it a great choice for piling on weekly volume without feeling beat up. The shoe’s combination of comfort and liveliness is rare—few max-cushioned trainers feel this eager to move.
Weight, Drop, and Stack Height
- Weight: 7.7 oz men & women
- Drop: 8 mm
- Stack height: 45/37 mm
Comfort for Everyday Runners
The ASICS Megablast may look like a max-cushion monster, but it feels surprisingly friendly underfoot. That generous stack of FF TURBO² foam works overtime to absorb impact, reducing fatigue on long efforts. For everyday runners, that means you can log miles without your knees, hips, and lower back staging a protest the next morning. Softer cushioning doesn’t just feel nice; it spreads out the shock of each step, protecting the joints that tend to complain first.
Despite all that foam, the Megablast stays light for its class, so you’re not weighed down on longer runs. Less strain means fresher legs, and fresher legs usually mean fewer excuses to skip tomorrow’s workout. Add in excellent breathability from the thin, airy mesh upper, and you’ve got a shoe that helps keep swelling and hotspots at bay—no “oven feet” here.
Put it all together and the Megablast delivers comfort that lasts beyond the run itself. It’s the kind of shoe that feels good not just when you lace it up, but hours later when you realize you’re not limping around the house. For everyday runners, that’s the kind of comfort that really counts.
Durability & Traction
The ASICS Megablast uses ASICSGRIP rubber in all the right spots (forefoot and heel), so you get dependable traction on both dry pavement and those surprise wet patches that always seem to appear right when you speed up. The catch? There’s not rubber everywhere. Most of what you’re landing on is exposed FF TURBO² foam, which keeps the ride soft and the weight down but may raise an eyebrow if you’re used to full rubber coverage.
The good news: this isn’t the flimsy foam of yesterday. FF TURBO² is more resilient than its predecessor, meaning it won’t scuff down as quickly as you’d think. The lighter feel is worth the trade-off, and unless you’re dragging your feet like a tired marathon finisher at mile 25, durability should hold up just fine.
As for lifespan, you’re looking at the usual 300 to 500 miles, depending on your running style and surfaces. In other words, the Megablast should last long enough to get you through a solid training block or at least until you’re tempted by next year’s new foam.

Definitely. Its plush cushioning and light build make it comfortable for all-day use. Just note at $180, you’re paying for premium running tech, not just walking comfort.

Runners who want a soft yet springy max-cushion trainer for long runs, recovery days, or steady workouts. Great for neutral runners looking to reduce impact on joints without sacrificing energy return.
Who shouldn’t buy it?
