ASICS Sonic Blast vs Nova Blast 5: Which Daily Trainer Fits Your Running?

Introduction

The ASICS Sonic Blast was built directly from the Nova Blast platform. ASICS took feedback from the Nova Blast and used it to create a speedier, more lively version: something more responsive, with better traction and more snap. That might sound like the Nova Blast line is being phased out, but it is not. ASICS simply wanted a faster sibling alongside it.

The result is an interesting comparison, because the two shoes share a surprising amount. Both carry the same weight and nearly identical geometry, yet they ride in noticeably different ways. Here is how they stack up.

Specs at a Glance

The Sonic Blast comes in at 46 mm of heel stack in men’s size 9 and 45 mm in women’s size 8, both on an 8 mm drop platform. That puts the forefoot at roughly 38 mm and 37 mm respectively. Weight is around 9 ounces (255 grams) at the sample size, and notably, the Nova Blast matches it with the exact same weight and specs.

The Nova Blast 5 runs 41.5 mm of heel stack in men’s size 9 and 40.5 mm in women’s size 8, again with the same one-millimeter difference between men’s and women’s sizing, the same 8 mm drop, and the same weight. In other words, the Sonic Blast adds a substantial amount of stack without adding a single gram.

Sonic Blast: Midsole and Plate

The Sonic Blast uses a new Flight Foam Turbo Squared midsole, an A-TPU based foam that is more resilient and lighter, allowing more foam without extra weight. It is very bouncy, but less compliant than Flight Foam Leap, the A-TPU foam used in ASICS racing models. This keeps the shoe training-focused, more durable, and better able to hold its structure. It feels similar to Flight Foam Turbo Plus, but slightly more compliant and even bouncier.

There is also a plate, called the Astro plate: a 3/4-length PEBAX plate that starts around the midfoot and spoons up into the forefoot with a sharp toe spring. The goal is a snappy, quick-rolling forefoot, and that experience clearly comes across.

Ride and Performance: Sonic Blast

This is a shoe that likes to go fast. It shines for uptempo work, whether that is an uptempo long run or sessions inside a marathon build where you want to build endurance without losing snap in your feet.

Transitions at slower paces are where things get trickier. The heel bevel is similar in size to the Nova Blast, but with much more foam and a 3/4-length plate, the midfoot can feel rigid and slightly slappy coming off the heel. At faster paces you compress into it quickly and snap off the forefoot, producing a trampoline effect that rolls forward beautifully. From the midfoot forward, it feels great, and if you land more forward, it could even work on easy days.

It also does not feel unstable at 45 mm of stack, which is an achievement in itself. That said, the heel and midfoot transition could be refined, perhaps with a more laterally biased bevel or a half-length plate instead.

Ride and Performance: Nova Blast 5

The Nova Blast 5 feels very balanced. Its Flight Foam Blast Max midsole is slightly more compliant and softer underfoot, but it lacks the spring of Flight Foam Turbo Squared. With no plate, more balanced geometry, and slightly taller sidewalls, transitions are smoother across a wider variety of uses.

One clear improvement over the previous Nova Blast is traction. Complaints about slick-conditions grip led ASICS to fit a high-abrasion ASICS Grip outsole, and it genuinely feels more tacky and holds the ground better. For daily training and easy miles, the Nova Blast still wins.

Upper and Fit

The Sonic Blast upper feels more performance-oriented while remaining training friendly. The jacquard mesh is thinner and airier but breathes well, with a padded tongue similar to the Nova Blast, a semi-rigid heel counter with less padding, and good lockdown. It feels streamlined throughout, with noticeable perforations that look sharp.

The Nova Blast 5 upper feels more plush, with visibly more padding around the heel collar. Width-wise, both are similar: normal through the heel and midfoot, slightly wide in the forefoot, with good volume and plenty of room for swelling. The Nova Blast is the friendlier daily upper; the Sonic Blast is the lighter, airier one.

Which One Should You Buy?

The Sonic Blast retails at $180, which is reasonable for what it delivers. The Nova Blast sits where it always has, in the $140 to $150 range. Both are excellent shoes capable of putting in serious miles.

If your priority is daily miles and easy running, the Nova Blast 5 remains the better pick. If you want something snappier and speedier at the same weight, with more stack and more resilient foam, the Sonic Blast is the stronger choice, and it will handle uptempo work better than the Nova Blast ever did. The two overlap enough that some runners could happily own either, but they are distinct enough to be different lines entirely.

Conclusion

ASICS took the Nova Blast formula and pushed it in two directions: the Sonic Blast trades plushness for stack, bounce, and a snappy plated forefoot, while the Nova Blast 5 doubles down on balanced, comfortable daily training. Choose the Sonic Blast for speed days and marathon builds, and the Nova Blast 5 for the easy miles that make up the bulk of your week.
