I was excited to try the ASICS Megablast, although if we’re being honest, the first run was not my favorite (I’ll get into that later). If you’ve loved how bouncy the Superblast and Novablast feel but wanted something lighter and livelier than a daily trainer without going full race-day plate, this ASICS Megablast review can help decide if it’s that middle lane you want.
I’ve never been a huge Novablast fan. I know it’s a crowd favorite, but it isn’t mine. I’ve always wanted something “more” from that shoe. It is just okay in my opinion. I really liked the original Superblast but the Superblast 2 was just ok as well. The Superblast is also just a lot of shoe and many people don’t want or need all of that. The Megablast sits right between the Novablast and Superblast. So I was hoping maybe I would like the Megablast the most.
ASICS Megablast Review: Questions I Had Before Running
Is the ASICS Megablast good for long runs?
Yes. The Megablast’s high stack of FF Turbo Squared foam provides deep cushioning without feeling mushy, which makes it ideal for long runs or high mileage. The rocker geometry smooths transitions and keeps your stride efficient even after fatigue sets in.
How does the ASICS Megablast compare to the Superblast 2 or Novablast 5?
Think of it as the middle ground. The Superblast 2 is the plushest and most maximal option, while the Novablast 4 leans toward daily-trainer comfort. The Megablast sits between them, lighter and snappier than the Novablast but less extreme than the Superblast.
Does the ASICS Megablast run true to size?
Mostly, yes. Length runs true, but the forefoot has a more tapered shape. This taper shape is common for ASICS running shoes in general. Runners with wider feet or who prefer extra toe room might consider sizing up half a size. For most neutral-width runners, true to size works fine.
Is the ASICS Megablast worth the $225 price tag?
If you log consistent mileage and want a trainer that bridges daily and workout needs, it justifies the cost. You’re paying for the FF Turbo Squared midsole and decent durability. If you only need a soft recovery shoe, it might be more than you need, but for performance-minded runners, it’s mostly in line.
Who should buy the ASICS Megablast and who shouldn’t?
Buy it if you’re a neutral runner who likes energetic cushioning and wants one shoe for everything from easy runs to tempo sessions. Skip it if you need motion control, prefer an ultra-soft feel, or want a race-day shoe.

ASICS Megablast Fit and Sizing Review
Was getting an all-white version of the shoe to run in the desert the best idea? No, and now they’re a nice mix of orange and brown. We know color doesn’t matter in a running shoe but I do like the all white version. Anyway, let’s get into fit.
Most ASICS shoes fit long and narrow, and the Megablast is no different. The engineered mesh is thin, breathable, and dries quickly, which helps on hot road days and long runs where feet tend to swell. A lightly padded heel collar and a firm counter create solid rearfoot lockdown without rubbing, and the gusseted tongue stays centered. The best running shoe uppers disappear on your feet, and I’ve found the Megablast doesn’t have any hot spots.
Length runs true for most, but the forefoot is on the tapered side, so runners who need extra space in the toe box should try before buying or consider a half size up. The toe box fabric has a little give but not much, which keeps the fit secure at faster paces and during cornering but may feel snug for wide feet.
In running shoes, I wear between a women’s size 10–11 wide and found the size 11 to fit the best. If you have wider feet, you’ll likely need to size up half a size.
If you came here for an ASICS Megablast review focused on sizing, the short answer is true to size for most, half up for wide feet.
How the ASICS Megablast Feels on the Run
The midsole is where the magic happens. FF Turbo Squared delivers that trampoline-style bounce but tempers it with more control than pure marshmallow foam. I’ve found too soft and mushy shoes can make the pad of my feet hurt so this is nice. The rocker helps you roll off the forefoot smoothly, and the geometry encourages a forward feel at daily paces and steady efforts.
You get clear energy return without the stiffness of a plate, which many runners will appreciate on days you want pep without rigidity. Compared to the Superblast 2, the Megablast feels slightly more responsive with a similar max-stack cushion underfoot. It’s been easier to pick up the pace in the Megablast.
Where does the Megablast fit in my rotation? Honestly, at first I didn’t like it. The first try-on felt bulky, and I actually took them off and decided to try another time. After logging a few miles, it changed my mind. It’s comfortable, balanced, and smoother than it looks.
It’s a great all-around shoe, something I can pack when I’m unsure what kind of run I’ll do. If I’m doing pure speedwork, I’ll grab something faster, but for daily mileage, this is a reliable choice.
ASICS Megablast Durability and Traction
ASICSGRIP coverage is placed where it matters. On damp roads and light grit, traction holds up well. The tradeoff is that rubber doesn’t cover the entire bottom, which keeps weight down but slightly limits durability.
I’ve taken the Megablast out on light desert trails with no issues. Based on wear so far, I expect around 300 to 400 miles of life. The lack of rubber on key areas might shorten its lifespan a bit, but overall it should last about as long as most daily trainers.
ASICS Megablast Review Conclusion:
The Megablast is bouncy without being sloppy, light without feeling thin, and protective without dulling your stride. Once you get used to it, it’s a fun shoe to run in. It’s one of those models that grows on you with each run and starts to make more sense the longer you wear it. The ride feels efficient yet forgiving, and the FF Turbo Squared midsole keeps the experience fun even after long efforts.
If you’re someone who enjoys the Novablast but wants a bit more stability and a sleeker feel, or if the Superblast feels like too much shoe, the Megablast is right in the middle. Over time, I’ve found myself reaching for it on days I just want something that feels fast without needing to think about pace. It’s not a wow shoe on the first run, but it becomes one the more you use it, and that might be its biggest strength.
For anyone skimming this ASICS Megablast review for the gist, it’s a solid yes if you want one shoe that can do a little bit of everything.
