ASICS Superblast 3 review verdict

The ASICS Superblast 3 is a premium, plate-free supertrainer built for long runs, daily mileage and marathon-pace work. Its new FF LEAP top layer makes it softer, lighter and more energetic than the Superblast 2. The trade-off is stability: runners who preferred the firmer control of version 2 may find the taller, softer ride less planted.

Cushioning, ride and performance

FF LEAP is the defining update. It compresses more readily than the Superblast 2’s FF TURBO PLUS, while the firmer FF BLAST PLUS carrier, broad footprint and sidewalls prevent the platform from feeling shapeless. Independent testing has reported very high shock absorption at both heel and forefoot, but the sensation is protective rather than aggressively propulsive.

The Superblast 3 works best during long, mostly straight-line efforts. Its low weight, rocker and forefoot cushioning help maintain comfort late in a run, and it moves smoothly from easy pace into marathon pace. It can also handle controlled tempo sessions, although the tall stack feels less precise through tight corners or short, hard intervals.

Midfoot and forefoot strikers are likely to experience the smoothest compression and release. Heel strikers still receive substantial cushioning, but hard landings on the outer heel can create a brief wobble before the foot reaches the wider midfoot. It is a neutral shoe with supportive geometry, not a stability model.

Fit, sizing and stability

The Superblast 3 is generally true to length, with more usable forefoot room than the Superblast 2. Start with your normal running-shoe size. The fit remains standard rather than genuinely wide, so broad feet should check toe splay and lateral pressure instead of automatically adding extra length.

The woven upper is light and flexible, while reinforced eyestays and a semi-gusseted tongue improve containment. Narrow-heeled runners may notice mild lift with standard lacing; using the final eyelet for a runner’s loop usually improves lockdown without overtightening the midfoot.

The broad base and firmer lower carrier add guidance, but they cannot fully offset a soft 46.5mm heel. Runners with recurring ankle instability, marked overpronation or discomfort in tall shoes should test it before committing to long mileage.

Durability, walking and daily use

ASICSGRIP and AHAR LO cover the highest-wear areas, and independent abrasion testing suggests good rubber durability. The exposed foam through the centre may show cosmetic scuffing sooner, especially for runners who drag or twist through toe-off, but surface marks do not automatically mean the shoe is finished.

Do not rely on a fixed mileage promise. Replace it when cushioning becomes uneven, protection noticeably declines, the upper stops securing the foot or outsole wear reduces traction. The shoe can also be comfortable for walking and prolonged standing, although its height, softness and price are unnecessary for many casual walkers. It is designed for roads and smooth dry paths rather than technical trails.

ASICS Superblast 3 comparisons

Superblast 3 vs Superblast 2

Choose the Superblast 3 for a softer, lighter and more forgiving long-run ride. Choose the Superblast 2 if you value firmer transitions and greater inherent stability. Version 3 is an update in character, not an automatic upgrade for every runner.

Superblast 3 vs ASICS Megablast

The Superblast 3 offers more cushioning for long mileage and marathon preparation. The lower, firmer Megablast feels more direct for shorter tempo sessions and faster toe-offs.

Superblast 3 vs Nike Vomero Plus

The Vomero Plus prioritises soft daily comfort and a more planted sensation but carries more weight. The Superblast 3 is lighter and better suited to sustained faster running.

Superblast 3 vs Saucony Endorphin Speed 4

The nylon-plated Endorphin Speed 4 is sharper for intervals and tempo work. The plate-free Superblast 3 provides deeper protection and a less prescriptive ride over long distances.

Who should buy the ASICS Superblast 3?

  • Neutral runners training for a half marathon or marathon.
  • Runners wanting maximum cushioning without a carbon plate.
  • Anyone seeking one premium shoe for easy, steady, long and controlled tempo runs.
  • Superblast 2 users who wanted a softer ride and roomier forefoot.
  • Heavier runners who value cushioning that resists bottoming out.

Who should skip it?

  • Runners who need a dedicated stability shoe or strong medial guidance.
  • Anyone uncomfortable on very tall, soft platforms.
  • Athletes wanting a nimble shoe for short track intervals and sharp corners.
  • Superblast 2 fans who specifically prefer its firm, controlled ride.

At £200, the shoe makes most sense when it replaces both a maximum-cushion daily trainer and a non-plated long-workout shoe.

Final verdict 9.0/10

The ASICS Superblast 3 combines excellent long-run protection with useful pace versatility in a light, plate-free package. Its softer ride is both the upgrade and the caveat: better for runners who found version 2 too firm, less suitable for those who relied on version 2’s stability.

ASICS Superblast 3 FAQ

Is the ASICS Superblast 3 good for everyday running?

Yes. It handles easy runs, long runs, steady efforts and controlled tempo sessions. It may be excessive for runners who only complete short, relaxed runs.

Is the Superblast 3 true to size?

It is generally true to length with a standard-width fit and more forefoot room than the Superblast 2. Very wide feet should try it before buying.

Is the Superblast 3 a stability shoe?

No. It is a neutral shoe with a broad base, sidewalls and firmer carrier layer. These features add guidance, but the tall, soft stack can still feel unstable to some runners.

Does the Superblast 3 have a carbon plate?

No. Its rebound comes from FF LEAP foam, rocker geometry and the FF BLAST PLUS carrier.

Can you run a marathon in the Superblast 3?

Yes. Marathon training is one of its strongest uses. Its official 46.5mm heel exceeds the 40mm limit used in World Athletics road competition, so elite competitors should check current event rules.

How long does the ASICS Superblast 3 last?

Durability depends on gait, surface, body mass and rotation. Monitor uneven compression, reduced cushioning, upper security and traction rather than relying on one mileage figure.
