Asics Superblast 3 (2026 Review): The Best Super Trainer?

Asics is no longer resting on the success of its Gel line. The Blast line has become the brand’s most compelling showcase, a series of bold and innovative shoes that push the boundaries with every new model. And few releases were as highly anticipated as the Superblast 3.

The first two versions won over runners and testers alike, establishing themselves as true benchmarks. But the arrival of the excellent Megablast just before it raised a legitimate question: Does the Superblast 3 still have a reason to exist?

The answer is yes, without a shadow of a doubt. The shoe has its own distinct identity, a clearly defined place in the Blast lineup, and a midsole that takes things to a whole new level with an impressive 46.5 mm stack height.

Still, it’s not the only one on the market. Between the Novablast 5, the Megablast, and the new Sonicblast, figuring out which Blast is right for you is no easy task.

In this in-depth review, I’ll explain exactly how the Superblast 3 stands out from its sister models, and whether it’s the right fit for your running style.

Our verdict

Cushioning

Let’s start with the dimensions, because this is truly remarkable. Already imposing in the previous version, the height is now 46.5 mm at the heel and 38.5 mm under the forefoot.

It’s quite simply one of the shoes with the highest sole stack on the market today.

Only time will tell whether this growth will continue or if we’re about to hit a ceiling. That said, I don’t really notice much of a difference with the Superblast 3: the ride feels very similar to lower-stacked shoes.

The shock absorption is, of course, impressive: the shoe allows runners of all types to cover longer distances with comfort. Its limitations lie more in other areas, which I’ll discuss below.

There are two layers of foam, just like on the v2, but they’re different:

• On the top layer, FF Leap (replacing FlyteFoam Turbo+)
• On the bottom layer, FF Blast+ (replacing the FF Blast+ Eco foam)

The first is made of A-TPU (aliphatic thermoplastic polyurethane), which is currently the best material available. In fact, it’s the material used in racing models, such as the excellent Asics Metaspeed Ray.

According to the brand, it is 13.7% more responsive, 15% lighter, and 30% plusher compared to the previous FlyteFoam Turbo+ foam. These figures are hard to verify, but there’s no doubt that it’s better.

The FF Blast+ foam isn’t new, but its main purpose is to add a bit of firmness (and stability) to counterbalance the plushness of the first one. I think the result is very successful: the feel is very well balanced.

The blend leans (slightly) toward plush. The ride is a real pleasure, light and airy despite the height. The lack of a plate provides good flexibility and makes the ride less demanding.

Overall, the feel on impact won over every runner I read or talked to.

Finally, the 8-mm heel-to-toe drop is standard and should suit all runners.

Energy Return

The shoe weighs 227 g / 8.0 oz in size 42, which is lighter than the v2 and is getting closer and closer to the 200 g / 7.1 oz mark, which is usually reserved for carbon-plated “rockets.”

The design features the signature geometry of the Blast line, with an asymmetrical, curved shape inspired by a trampoline and two Trampoline Pods (including an extra one at the front): you can feel it when you push off, with a higher bounce (though it doesn’t quite match the elite models).

The responsiveness is excellent, with good forward propulsion and smooth heel-to-toe transitions, although some would have preferred a more pronounced rocker.

Support and Stability

The maximum height had raised concerns that the shoe might be unstable. But that’s not the case at all.

I found the Superblast 3 to have very good stability, and I haven’t seen much negative feedback on that point.

This is due to the wide base, reliable traction, and precise lockdown. There isn’t much difference compared to more traditional shoes with a heel height of less than 40 mm.

This model is universal (for neutral and supinated foot types).

Foot Lockdown

I was impressed by the upper of the Superblast 2, I thought it was exceptional for such a lightweight shoe.

I might as well say it right off the bat: I enjoyed this new Superblast 3 just as much.

This is a prime example of its kind, showcasing the brand’s expertise. It is made of engineered woven mesh with varying densities and patterns: more structured at the bottom and on the sides, and more breathable in the toe area to facilitate airflow.

The combination of a thicker knit and very fine yarns ensures excellent breathability while still providing good warmth in cold weather. The numerous padding sections and seamless design offer great step-in comfort.

The interior is soft except in the toe area (it’s best to wear socks).

I found the stretchy gusseted tongue very comfortable. It moves with the foot without slipping.

However, it didn’t win everyone over: some runners would have liked more padding. Perhaps they expected even more given the shoe’s high price, but personally, I thought it was very well-designed.

The rigid heel counter is also well-padded and effectively keeps the heel in place.

The lacing system now combines eyelets and laces to better adapt to your foot: the first two at the front go only through the laces, and the next two go through both the laces and the eyelets.

The benefit? It leaves more room in the forefoot when needed while providing better midfoot lockdown.

This provides a secure, comfortable foot lockdown that’s perfectly suited for long distances.

Sizing and Fit

It’s hard to make sense of all the conflicting opinions.

Some mention that the fit is narrow, while others feel there is too much room in the front.

Given the large number of shoes I test, I think I can offer some insight to help you make a decision.

I have fairly wide feet, and the shoe felt great on me. I didn’t find that there was any more room than in other similar models I’ve tested. Plus, the stretchy upper (and new lacing system) allows it to adapt to a wide variety of feet.

The length is standard.

I recommend choosing your usual size, or even half a size smaller if you have narrow feet (try them on).

Traction

As with the previous version, Asics uses ASICSGRIP outsole rubber in the impact zones (the design is nearly identical). The only real difference is the new Trampoline Pod (mentioned above).

Traction is strong on all surfaces, including wet ones.

The numerous grooves and micro-grooves provide excellent flexibility.

The design prevents pebbles from accumulating, so you’ll be able to run on dirt and gravel paths.

Use Scenarios

My concern going into this test? That I wouldn’t be able to tell the difference between the Superblast 3, the Sonicblast, and the Megablast. That concern vanished as soon as I took my first few strides.

What defines a shoe, beyond its spec sheet, is how it feels upon impact. The Superblast 3 is the only model in the lineup to feature FF Leap foam, and you can feel it right away. The plush feel is reminiscent of the latest Metaspeed line, offering an enjoyable ride that fans know so well. With no plate to counterbalance it, the FF Blast+ takes on that role, creating a very successful combination.

Asics promised a unique experience and high performance. They delivered on that promise. The shock absorption is excellent, and it works well for all types of running, whether in racing or training.

Some people think it’s too demanding for beginners, but I don’t agree. It’s still much more accessible than carbon-plated shoes. It’s more likely to be the price that puts a beginner off, not the shoe itself.

Comfort is excellent, with a plush feel and a bounce that won runners over across the board. It is also more versatile at moderate paces than the firmer previous version. It has plenty of pop: tempo workouts are a pure pleasure, and it excels at incorporating marathon-pace segments into a long run.

For short bursts of speed, such as a 400-meter sprint, the Megablast will perform better. The lack of a plate and its plush feel may limit its use in this context, although a large part of the pack will still be perfectly happy with it.

In racing, carbon plate models like the Metaspeed Ray will remain more responsive. But in the category of shoes without carbon plates, the Superblast 3 is the best option available today for the marathon.

Quality and Lifespan

The durability is very good.

The ASICSGRIP outsole rubber is durable, and the upper shows no signs of wear after about 100 kilometers.

The foams should also retain their properties (cushioning and responsiveness) well over time.

The Superblast 3 should therefore last quite a while (you can bet on more than 600 km). But at a premium launch price, the value for money will depend on your expectations. You’re mainly paying for the cutting-edge design.

From an environmental standpoint, the Superblast 3 features recycled polyester in its upper, a dope-dyed inner lining designed to reduce water consumption during production, and bio-based materials in the midsole.

This product contains no animal-derived materials (vegan).

Conclusion

The Asics Superblast 3 takes things a step further, with an even more maximalist midsole that incorporates the excellent FF Leap foam for greater versatility.

In my opinion, this is the most polished shoe in the Blast line.

It’s among the best for training and an excellent marathon choice for runners who don’t want a carbon plate.
