The Asics Superblast 3 arrives as a significant evolution of one of the brand’s most popular performance trainers, bringing a new midsole compound and a noticeably different ride feel. On paper, it remains a premium non-plated “super trainer,” but in practice it now feels closer to a high-end daily marathon shoe than a rigid tempo cruiser.
The headline update is the midsole, which now blends FF Blast Plus with the new FF Leap foam, previously reserved for Asics’ top racing models. According to Asics, FF Leap is 33% lighter and 13% more responsive than FF Blast, while still offering enough cushioning for daily training.
The stack height is slightly higher than the Superblast 2, yet the overall shoe is lighter. A trampoline-inspired forefoot outsole geometry is designed to improve toe-off energy return, while the engineered woven upper improves breathability and moisture management. A gusseted tongue and wing system helps lock the midfoot down securely.

Asics Superblast 3 review
The Fit
The fit is true to size and extremely comfortable. There’s generous space in the toe box without feeling sloppy, and the midfoot sits at an average width. Runners with slightly wider feet should appreciate the forgiving forefoot, while the padded heel and tongue make it easy to achieve a secure lockdown. The shoe feels plush on foot without becoming bulky, and it’s comfortable straight out of the box.

The Run Test: Likes
The standout feature of the Superblast 3 is the new FF Leap midsole, which delivers a softer, bouncier and more energetic ride than previous versions. Compared to the Superblast 2’s firm and rigid feel, this update makes the shoe far more comfortable for long runs and steady marathon-pace efforts.
It provides a smooth, natural ride that helps maintain consistent pace without feeling aggressive or forcing speed. The shoe also works much better at easier paces, making it more versatile across daily training than before. Fit is another strong point: true to size with a forgiving toe box, secure midfoot lockdown and plenty of comfort through the upper thanks to the padded tongue and collar.
The wide base still offers good overall stability for most runners, even over marathon distances, and the outsole shows solid durability and grip. Overall, it feels like a more refined, performance-focused version of the Asics Novablast 5.

The Run Test: Dislikes
The softer FF Leap foam also introduces some compromises. Stability is reduced compared to the Superblast 2, which had a much firmer and more planted base. Runners who valued the previous model for its solid, controlled platform may find this version slightly wobblier, particularly when fatigue sets in.
While the shoe delivers good energy return, it lacks the instant responsiveness needed for sharp interval sessions or short repeats, making it less suitable for high-intensity speed work. It performs best once you settle into a rhythm rather than when frequently changing pace.
The price is another downside: at £200 / $210, it is expensive if mainly used for easy or steady runs. Finally, runners who prefer a firmer, more traditional tempo shoe may not enjoy the softer, bouncier ride, as the Superblast 3 feels like a different shoe compared to the Superblast 2.

Verdict And Alternatives
The Asics Superblast 3 is a refined and more approachable version of its predecessor. It shifts away from the firm, tempo-focused feel of the Superblast 2 and toward a softer, bouncier, more marathon-friendly ride. It’s an excellent option for runners who want a premium training shoe for long runs, steady efforts, and even marathon racing without stepping into carbon-plated territory.
The main drawbacks are its high price and reduced stability compared to the previous model. Runners who prefer a firmer, more controlled platform may still prefer the Superblast 2, while those wanting maximum speed and responsiveness may look elsewhere.
But for runners seeking comfort, energy return, and versatility from easy runs up to tempo pace, the Superblast 3 is a standout update and likely to become a favorite for long-distance training.
Other options you might look at include the slightly more speed-focussed Asics Megablast, the very similar R.A.D UFO and cheaper alternatives like the Adidas Adizero Evo SL.
Asics Superblast 3 vs Asics Megablast
The Megablast has a lot of similarities with the Superblast 3 but skews more towards faster sessions, providing a more responsive ride but still allowing for a high level of versatility. Both shoes excel as tempo efforts and long runs, but the Superblast 3 is slightly softer and better suited to effort at the easier end of the spectrum.
Asics Superblast 3 vs R.A.D UFO
The Superblast 3 and R.A.D UFO are both excellent shoes if you’re looking for a fun, bouncy option that eats up miles. Aside from the price, the main difference is a slightly more pronounced rocker in the UFO and a touch more responsiveness.

Tom heads to the Seville Marathon 2026 for the launch of the Asics Superblast 3, taking the opportunity to test the shoe out over 26.2 miles. It’s fun, soft and bouncy, and meant that he crossed the finish line with a smile on his face.
