A comparability of the newly launced Asics Megblast vs Sonicblast from our assessments. These are two model new footwear designed extra for the typical runner to get a style of that light-weight velocity.

I’ve mentioned beforehand ASICS likes to confuse us with names just like the Metaspeed Sky vs Metaspeed Edge that are the identical, however the identical in any respect. And now we’ve an entire line up of Blast footwear, which is certainly intentional as extra manufacturers go to this silo method to outline a household of footwear.
Right here’s a rundown of how the model breaks out footwear proper now, the blast line up is the primary collection with out their trademark historic Gel (assume Gel Nimbus, Gel Cumulus). And the road has actually introduced them again to the forefront of runners minds.
- ASICS Novablast 5: Day by day coach with good quantity of cushion, not made to select up the tempo.
- ASICS Superblast 2: Light-weight, nice cushioned coach that may decide up the tempo and carry many by means of their marathon feeling actually secure.

We’ve received extra particulars on every of those new footwear beneath from our testing, however answering a few of your fast questions first.
For these ready on updates to the prevailing footwear, we’re taking a look at March 2026 for the Superblast 3 and July 2026 for the Novablast 6. That provides these two new footwear a while for everybody to know what they’re and see how they slot in to a working shoe rotation.
ASICS Sonicblast vs Megablast
Contemplate this your fast comparability after which we’ll dive in to some further particulars and opinions.
One factor these footwear each share is a model new midsole, FF Turbo Squared. This can be a key distinction maker in these footwear and in addition another excuse, they launched concurrently. It’s positively made to be mild and mean you can really feel like you may decide up the tempo, however it’s a totally different feeling than the highest tier FF Leap which actually bounces.
New now usually means they’re taking an current foam and doing a little remixing. It’s an enchanting technical course of that I received’t bore you with, however ends in some large positive factors for these footwear.
After all, the query on my thoughts was will this new tremendous foam be as sturdy. ASICS mentioned of their testing it meets all the traditional sturdiness requirements, which sounds slightly like a politician answering with out answering. As famous, we’re testing these proper now and could have some ideas.
- Each are very light-weight with out being a high tier racing shoe
- Each make the most of this mild, bouncy foam
- Megablast is ENTIRELY the brand new foam, Sonicblast is a combo of foams
- Sonicblast has a plate
- Megablast is lighter with a bit extra cushion
- Megablast is unisex sizing and higher jogs my memory extra of a racing shoe
- Each generally is a day by day coach or race day shoe

ASICS Megablast Overview
We’re beginning with the non-plated and but lighter weight of the 2 footwear! I used to be tremendous intrigued and needed to search out one of the best ways to explain this cushion, so I ran across the block in 5 totally different footwear. Not bizarre in any respect.
If I needed to decide the closest feeling underfoot it might be the a lot cherished Adidas EVO SLbesides that is even lighter. Pulling it on will instantly offer you that race day shoe feeling with the skinny woven higher, skinny tongue and frivolously padded heel collar.
They name this the bounciest shoe they’ve, however placing it on subsequent to the Metaspeed I disagree. Presumably as a result of the Metaspeed is softer and offers extra rebound. That being mentioned it’s nonetheless a enjoyable journey.
Having examined this shoe from 7:30 tempo to 12 minute tempo, it may well do all of it.
BUT for me if the objective is something 9 or underneath I’d go for a special shoe. I really actually loved the journey at that 9:30-12 tempo.
I’m thrilled to see a model spend a while fascinated with the gait and the wants of these not simply working a 3 hour race, however those that are able to have a very robust race day at 5 hours! Lighter weight can add up over the miles and the rocker, geometry and bounce will certainly assist with the stride persevering with to really feel good.
Not a shoe for strolling round, however the shoe you need if you’re placing in some longer miles or these days the place you’re enjoying with velocity. No, we don’t all want or need a plate. The froth performs an enormous position in a footwear potential to select up the tempo and also you’ll discover that right here.
In contrast to a regular max cushion working shoe, say the tremendous cozy Asics Gel-Nimbusyou received’t be sinking in to the cushion or dropping vitality to it’s softness.
Some of us might not love that feeling and would like the softer shoe total, so it’s going to come back right down to a bit of non-public desire underfoot. In truth, whereas I believe I may go sooner on this shoe I’d like the general really feel of the Superblast 2 higher.
We normally do that per shoe, however these two share so many traits that we’re doing a joint who’s the Megablast good for:
- Vast Toes: Unisex sizing means it’s slightly extra accommodating and much wider than most race footwear, however not a large match. Toebox may use extra room.
- Heavier Runners: The froth is able to carry you the space and won’t overly compress.
- Lengthy Runs: Designed with marathon coaching in thoughts.
- Entrance of the Pack: No. It’s not your shoe, keep in your lane.
At a 45mm stack the shoe feels extraordinarily secure because of the actually extensive base. This can be a frequent function of the blast line that we respect.
- Very drop: 8 mm
- Stack: 45 mm
- Weight: 8 oz (word precise weights are coming in lighter than specs record)
- Out there in 2 colours
- Not accessible in Vast, Unisex match
- Out there on Asics.com for $225
As anticipated with a lighterweight shoe, we don’t have a full ASICSGRIP rubber protection on the underside. Once more this leads us to surprise about sturdiness, so we can be checking again after 100 and 200 miles. Asics says they’ve examined it in opposition to their requirements and it ought to be as sturdy as a day by day coach.
Of those two footwear, the Megablast on the increased value level could be the extra effectively rounded shoe for lengthy runs to tempo pickups, when you’re on the lookout for only one choice.

Lengthwise I’m tempted to inform you to go up a 1/2 dimension. Possibly it’s simply that the toebox is pretty shallow and also you’re rocking ahead, however I actually needed a bit extra room.
Although it’s Unisex sizing I didn’t run into any points with my foot slipping round. I admit this can be a peeve of mine and I want manufacturers would begin getting per making race type footwear in each a female and male final.
Love the laces in right here having the ridges. This can be a new factor for a lot of manufacturers on their race type footwear and it completely appears to assist with preserving them tied. Heel lock lacing was wanted on this shoe, which might be because of the Unisex match which modifications the heel cup. And it’s a VERY brief lace to try to make that occur.
Tongue has no padding and is hooked up to stop transferring round. General going to assist hold the warmth down, which is nice as our toes already swell throughout marathon runs.
Heel collar is frivolously padded and had no points. As with each race type shoe, I do want there was a bit extra room within the toebox and I believe some might want extra quantity within the mid-foot.
ASICS Sonicblast Overview
A big contingent of runners have been asking ASICS for a Novablast with a plate, aka one thing mild with good cushion that may go only a hair sooner. As a substitute of simply inserting a plate, they got here up with this new foam and put in a PEBAX plate to make it extra extensively accessible and usable than the carbon plated race day footwear.
The three/4 size PEBAX plate (known as an Astroplate) goes to be extra versatile, which is vital because the gait of a 4 hour runner is totally different than a 3 hour marathon runner. Lots of the entrance pack race footwear are too stiff for on a regular basis athletes and will contribute to decrease leg accidents.
Whereas the Megablast is fully the brand new Flyte Foam Turbo Squared, the Sonicblast stored the identical backside layer because the Superblast (FF Blast Max). That is the place we begin to perceive how totally different foams give us a special really feel and velocity in a shoe.
Personally, I loved the journey of this shoe extra. I believe it’s fully associated to that backside layer of froth that’s additionally used within the Novablast. I really assume that heavier testers have gotten extra bouncy and benefit from the Megablast extra.
The Sonicblast has a direct really feel of a shoe that’s prepared to select up the tempo. Not a bouncy tremendous shoe, however a shoe that’s going to really feel actually good for a 4 hour marathon. Sure, that is the cheaper of the 2 footwear which is stunning because it has a plate, however once more reveals you that foam makes a distinction.
I’ve used this shoe for a few simple runs and a few tempo runs. It carried out effectively in each, however was very nice on that slight decide up. As a result of it’s plated, it wouldn’t be my go to for day by day coaching. Nonetheless, I’d fortunately take it out on longer miles with objective paced efforts figuring out that it’s going to nonetheless really feel high-quality on these simple miles in between.
Even with the massive stack peak, this one by no means felt like a max shoe to me. That’ s an excellent factor.
We normally do that per shoe, however these two share so many traits that we’re doing a joint who’s the Sonicblast good for:
- Vast Toes: Common match, probably not designed for extensive toes.
- Heavier Runners: Good foam set as much as deal with impression and forestall bottoming out.
- Lengthy Runs: Designed with greater miles in thoughts.
- Entrance of the Pack: It could actually deal with some sooner paces, however is designed for the center of the pack.
The marginally sooner shoe is at a barely lower cost, which may shock a few of you! It’s nonetheless a effectively rounded shoe, however possibly much less day by day coach as a result of we simply don’t want a plate on a regular basis.
- Very drop: 8 mm
- Stack: 46 mm
- Weight: 7.8 oz ladies’s, 9 oz males’s (word precise weights are coming in lighter than specs record)
- Out there in 3 colours
- Not accessible in Vast
- Out there on Asics.com $180

Oddly or sadly they didn’t lengthen the textured laces to this shoe, however I really feel like that might be the following replace which can even drop a tiny quantity of weight. In any other case, no points with the match.
It’s true to my regular size and with ladies’s sizing, it goes again to a bit extra slim match. Wouldn’t complain in the event that they discovered a method to improve the toe field in each footwear, however I additionally didn’t have any points with rubbing.
The tongue is skinny and hooked up, whereas the higher feels extraordinarily breathable. That makes me need to take this out for some arduous summer season miles feeling like my toes would keep cooler, but in addition may swell a bit and really feel high-quality. Proper now 8 miles is my longest run in them.
