Asics Superblast Review: A Super Trainer That Does More Than Easy Miles

Introduction

Some shoes sit neatly in a category. The Asics Superblast resists that. It is officially a super trainer, not racing legal, yet after putting 35 miles on it in three days, the picture that emerges is of a shoe that is far more capable than that label suggests. It is exceptionally light, it rides with a controlled bounce instead of a mushy sink, and it handles everything from easy runs to hard threshold work.

Specs and Underfoot Feel

The numbers tell part of the story. The Superblast carries 45.5mm of stack height in the heel and 37.5mm in the forefoot, for an 8mm drop. Despite that tall platform, it weighs just 239 grams in a men’s size 9, about 8.4 ounces, making it one of the lightest, if not the lightest, super trainers available.

The midsole uses a large volume of FF Turbo foam with a thinner layer of FF Blast Plus underneath. The Turbo here delivers a controlled, lively bounce that feels solid rather than soft. It is not mushy at all, which is the most common complaint with maximal shoes. If you have tried other tall-cushioned trainers and found them too unstructured, this is the shoe that fixes that.

Fit and Comfort

The fit is a little snug in the forefoot, with a very thin, light mesh upper that keeps weight down. The midfoot and forefoot width are more normal, so most runners should not feel squeezed, but anyone with wide feet may want to test it first.

The heel counter is small and light, and it does an excellent job of locking the heel in place without any rubbing or irritation from the mesh padding. For a shoe this minimal in the upper, the overall lockdown is impressively secure.

Ride and Performance

There is no plate in the Superblast, which may come as a surprise given how stiff it feels out of the box. That initial stiffness breaks in over the first runs, and it plays a real role in what the shoe can do: it helps the Superblast handle uptempo running surprisingly well.

The geometry is where things get interesting. There is a solid bevel in the rearfoot that can feel like you contact slightly early at first, until the foam breaks in and the ride smooths out. Up front, the shoe has a very aggressive toe-spring and forefoot rocker that snaps really well as soon as you pick up the pace.

That combination makes this a genuinely versatile trainer. Easy runs feel comfortable and protected, but the shoe truly shines on faster work. A threshold session in it felt excellent, and that is not something most super trainers can claim.

Buying Advice

The Superblast is worth a serious look if you want a single shoe that can cover a wide range of runs. It suits runners who want the cushioning of a super trainer without the mushy feel, and who want something light enough to double as a workout shoe.

Keep the fit in mind: the forefoot runs snug, so narrow to medium-width feet are the safest bet. And since it is not racing legal, it is best framed as a training shoe with more than enough speed for the hardest days of your week.

Conclusion

The Asics Superblast earns its place by refusing to compromise. It is one of the lightest super trainers out there, it rides with a controlled and energetic bounce, and its stiff, rockered geometry lets it handle uptempo work that most cushioned trainers cannot. If you are shopping for a super trainer and want one shoe that can do a bit of everything, this is an easy recommendation.
