Asics Novablast 4: First Thoughts on a Tamer, More Classic Daily Trainer

Introduction

The Asics Novablast 4 has a lot of history behind it. Since the original launched back in 2019, the line has grown into a fan favorite and one of the most recognizable neutral daily trainers around. This newest version keeps that identity but shifts it noticeably. It feels tamer, a little less racy, and more like a classic daily trainer than an all-purpose do-everything shoe. That change will excite some runners and divide others, so it is worth understanding exactly what moved before you upgrade.

What Has Changed

The upper is the first thing you notice. It is softer and more structured than the previous Novablast, and slightly less streamlined. The look brings to mind other recent Asics trainers, and there is a growing sense that the brand’s uppers, from the Cumulus to the Nimbus to this shoe, are starting to resemble one another. Comfort is up, but some of the Novablast’s outlier personality is gone.

Underfoot, the midsole is the full-length FlyteFoam Blast Plus with a sustainability twist: roughly 20 percent of the foam blend comes from recycled or eco materials. Stack height sits at 41.5 mm in the heel with an 8 mm drop, about half a millimeter more stack than before. The foam itself feels slightly firmer than the prior version, which gives the ride a steadier, more settled character.

How It Runs

On the run, the shoe feels good, but the character has shifted. It does not feel dramatically different from the Novablast 3 at first, though the firmer foam is noticeable and the overall package seems to have drifted away from the pick-up-and-go versatility the line was known for. This is now a more cushioned, more conventional daily trainer, with extra cushioning under the forefoot in particular.

The shoe gained roughly half an ounce, weighing in around 9.3 oz in a men’s size 10 versus about 8.9 oz previously. That is not a big deal in practice, but it reinforces the sense that this version is a touch more built-up than its predecessor.

Outsole and Grip

The outsole uses AHAR low rubber, a lower-density version of Asics’ long-lasting compound that is noticeably more tacky and slightly thicker than before. Some runners found the previous Novablast’s rubber slick, and this version clearly addresses that complaint with better grip underfoot.

For anyone who ran in the Novablast 3 and loved it, this is the area most likely to feel like a genuine improvement rather than a change in personality.

Who Should Buy It

Runners who found the Novablast 3 too lively or unstable will likely appreciate the calmer, more predictable ride here. Fans of firmer, structured daily trainers such as the Gel-Nimbus 24 should feel at home, since the ride similarity is hard to miss. The Novablast 4 still separates itself from the Superblast, but it no longer stands apart from the wider Asics lineup the way earlier versions did.

On the other hand, devoted fans of the Novablast 3’s springy, energetic feel may prefer to stay put. This version divides people, and the pattern of opinion across the line’s history, loving one version and not the next, seems likely to continue.

Conclusion

The Novablast 4 is a comfortable, well-gripped, slightly firmer daily trainer that trades some of the line’s signature bounce for a steadier, more classic ride. If you want a tame, cushioned everyday shoe, it is an easy recommendation. If you loved the Novablast 3 for its energy, try it on first.
