Looking for a shoe that can keep up with you during marathon training, without saving all the bounce for race day? The ASICS Superblast 3 and Megablast deserve your attention. They both occupy the premium training segment, but their design offers two different paths to choose from.
Our advice: start with the Superblast 3 if long runs are your priority. Try the Megablast if you are primarily looking for a highly dynamic foam to vary your pace. Comfort at your usual pace should be the deciding factor between the two.
Two approaches to premium training
The Superblast 3 introduces FF LEAP foam to this range. ASICS adds a responsive element to the forefoot and a woven upper designed to keep the foot secure over long distances. Its main advantage is offering plenty of cushioning in a shoe intended for training.
The Megablast relies on FF TURBO SQUARED foam and ASICSGRIP rubber. ASICS presents it as one of its bounciest training models. It’s an option to consider when you want an energetic feel alongside generous cushioning.
| Your priority | Model to try first |
|---|---|
| Consistent long runs | Superblast 3 |
| Pronounced bouncy feel | Megablast |
| Marathon prep with various types of sessions | Both, at your easy and sustained paces |
| Supplementing a racing shoe | Depends on the missing role in your rotation |
Which one for marathon prep?
Start by looking at your week. If your most important run consists of a long distance at a controlled intensity, focus primarily on the support, toe box space, and fluidity of the shoe after a few minutes of running.
If your long runs include marathon-pace blocks, look for a shoe that remains comfortable when you accelerate. The Megablast is an interesting candidate here, but the Superblast 3 also deserves a try: a more spectacular foam underfoot isn't automatically more pleasant for two hours.
For a runner who already owns a fast shoe, the new pair must meet a specific need. Are you looking for a model for long runs or a second tool for sustained sessions? That answer matters more than the most prestigious name.
Our verdict
The Superblast 3 is a good starting point for exploring a shoe designed for long training distances. The Megablast deserves a spot on your list if bounce is a major part of your running enjoyment. In either case, try the shoe while running at an easy pace: that is often the speed at which you will accumulate the most mileage.
Frequently asked questions
Is it useful to own both? Their roles may overlap. To build a rotation, one comfortable shoe for easy runs and a pair for racing might meet more distinct needs.
Is the bounciest one necessarily the best? No. The bouncy sensation must be accompanied by comfortable support and a gait that you control easily.
How to choose between them in the store? Wear your running socks and compare the two at your easy pace, then at a slightly more sustained pace.
