ASICS MEGABLAST Unisex Running Shoes
Maximum bounce. High-energy cushioning. A lightweight super trainer designed to make every kilometre feel faster.
The ASICS MEGABLAST is one of the most energetic shoes in the ASICS running range. Built around a full-length FF TURBO SQUARED midsole, the MEGABLAST combines a high level of cushioning with an unusually light, spring-loaded ride.
Unlike a conventional maximum-cushion trainer that prioritises softness and comfort above everything else, the MEGABLAST is designed around energy return. It is a neutral road-running shoe that can move from everyday mileage to long runs, tempo sessions and faster workouts without feeling like a traditional heavy cushioned trainer.
The result is a distinctive combination of maximum cushioning, high rebound and relatively low weight that makes the MEGABLAST particularly appealing to runners who want a versatile performance trainer without necessarily moving into a carbon-plated racing shoe.

What Is the ASICS MEGABLAST?
The MEGABLAST sits above the NOVABLAST in ASICS' performance-training hierarchy.
While the NOVABLAST 6 is an extremely versatile daily trainer, the MEGABLAST takes the concept of an energetic trainer considerably further. Its defining characteristic is the use of FF TURBO SQUARED throughout the midsole.
This gives the shoe a very high level of energy return without requiring a carbon-fibre plate.
It is best thought of as a high-stack, high-energy super trainer rather than simply another maximum-cushion running shoe.
FF TURBO SQUARED The Heart of the MEGABLAST
The most important component of the MEGABLAST is its FF TURBO SQUARED foam.
ASICS developed this foam to deliver a combination of low weight, softness and high rebound. The result is a midsole that compresses under load but rapidly returns energy as the runner progresses through the stride.
That characteristic gives the MEGABLAST its unusually pronounced bounce.
What you feel while running
- Soft cushioning when landing.
- High energy return through midstance.
- A springy sensation as you move towards toe-off.
- Less effort required to maintain momentum.
- A noticeably lively ride even at slower training speeds.
The foam is the reason the MEGABLAST can offer such substantial cushioning without feeling like a traditional heavy maximum-cushion shoe.
Maximum Cushioning Without the Heavy Feeling
The MEGABLAST has a very substantial amount of foam underfoot, with ASICS listing approximately 45mm of heel stack and 37mm of forefoot stack.
That gives the runner a large protective platform between the foot and the road.
However, the shoe remains surprisingly light for its stack height.
This combination is particularly valuable for runners who want maximum cushioning but do not enjoy the sensation of a heavy, sluggish shoe.
How Does the MEGABLAST Ride?
| Ride characteristic | MEGABLAST |
|---|
| Cushioning | maximum/high |
| Bounce | extremely high |
| Energy return | |
| Responsiveness | |
| Stability | |
| Long-run comfort | |
| Tempo performance | |
| Recovery running | |
The MEGABLAST is not a firm, aggressive racing shoe. Its performance comes from bounce and energy return rather than stiffness.
This makes it particularly appealing to runners who enjoy a cushioned ride but still want to feel propulsion beneath the foot.
The Rocker Geometry
The MEGABLAST uses a pronounced rocker profile to help move the runner through the gait cycle.
The geometry works with the highly responsive FF TURBO SQUARED foam rather than relying solely on foam compression for propulsion.
For heel strikers, the rocker can help move the shoe efficiently from landing towards midstance. For midfoot and forefoot runners, the substantial forefoot cushioning provides a highly protective platform for loading and toe-off.
The overall effect is a smooth, rolling transition rather than a traditional flat daily-trainer sensation.
Is the MEGABLAST a Stability Shoe?
No. The MEGABLAST is a neutral running shoe.
It has a substantial platform and can feel surprisingly stable considering its stack height, but it does not incorporate a dedicated stability system for controlling significant overpronation.
If you require structured stability, a model such as the ASICS GT-2000 or GEL-Kayano is a more appropriate starting point.
Who Is the ASICS MEGABLAST For?
The MEGABLAST is aimed at runners who want a highly cushioned shoe but do not want to sacrifice speed or energy return.
- Neutral runners wanting maximum cushioning.
- Runners who love a highly bouncy ride.
- Runners looking for a versatile super trainer.
- Runners who want a non-plated alternative to carbon racing shoes.
- Experienced runners looking for an energetic long-run shoe.
- Runners training for half marathon and marathon distances.
- Runners who want one shoe capable of handling easy and faster running.
- Runners who find conventional maximum-cushion shoes too dull or heavy.
MEGABLAST for Everyday Running
The MEGABLAST is capable of everyday mileage, but it is not simply a comfort-first daily trainer.
Every easy run has a noticeable level of bounce, meaning the shoe can make ordinary training kilometres feel more energetic.
For runners who like their daily shoes to have some performance character, this is a major advantage.
For runners who prefer a quiet, planted and predictable ride, the MEGABLAST may feel too lively.
MEGABLAST for Long Runs
This is one of the MEGABLAST's strongest applications.
