ASICS MEGABLAST Unisex Running Shoes
Maximum cushioning. Exceptional bounce. Lightweight energy for daily mileage, long runs and faster training.
The ASICS MEGABLAST Unisex is a high-stack neutral road-running shoe built around one defining characteristic: high-energy, highly responsive cushioning without the weight normally associated with maximum-cushion footwear.
At the heart of the MEGABLAST is FF TURBO SQUARED, ASICS' exceptionally lightweight and bouncy cushioning compound. Combined with a pronounced rocker geometry and a high-volume midsole, it creates a ride that feels energetic rather than simply soft.
With approximately 45mm of heel stack, 37mm of forefoot stack, an 8mm drop and a weight of around 223g in the unisex reference size, the MEGABLAST occupies an unusual position: it provides the cushioning of a maximum-cushion trainer while retaining the weight and responsiveness associated with faster performance shoes.
This makes it suitable for runners looking for a highly cushioned daily trainer that can move comfortably from easy kilometres to long runs, tempo work and faster training.

What Is the ASICS MEGABLAST Designed For?
The MEGABLAST is designed as a maximum-cushion, high-energy neutral trainer.
It is not simply a soft recovery shoe. Its purpose is to combine substantial underfoot protection with enough rebound and responsiveness to handle a surprisingly broad range of running speeds.
It is particularly suited to:
- Daily road running
- Easy runs
- Recovery runs
- Steady-state running
- Long runs
- High-mileage training
- Progression runs
- Tempo sessions
- Faster aerobic workouts
- Marathon training
- Long-distance training
- Selected race distances
The defining difference is that the MEGABLAST does not feel like a conventional heavy maximum-cushion trainer.
It is designed to give the runner maximum cushioning with a highly energetic ride.
FF TURBO SQUARED The Engine of the MEGABLAST
The MEGABLAST uses FF TURBO SQUARED, an advanced ASICS cushioning foam designed around low weight, softness and energy return.
The foam is engineered to produce a particularly pronounced rebound sensation.
For the runner, this translates into:
- High energy return
- Soft impact absorption
- A pronounced bounce
- Low weight relative to stack height
- Fast rebound after compression
- A lively sensation at multiple running speeds
The important point is that the MEGABLAST's cushioning is not simply about making the ride soft.
The foam is designed to give energy back.
That is why the shoe can feel surprisingly lively despite carrying a very substantial amount of midsole material.
Maximum Cushioning Without Maximum Weight
The MEGABLAST has an approximately 45mm heel stack and 37mm forefoot stack.
That is a substantial amount of material between the runner and the road.
Ordinarily, increasing stack height can result in a heavier and less agile shoe. ASICS has taken a different approach with the MEGABLAST by using a lightweight, high-energy foam to keep the overall shoe weight relatively low.
At approximately 223g in the unisex reference specification, the shoe has an unusually high cushioning-to-weight ratio.
This is one of its biggest advantages.
How Does the MEGABLAST Ride?
| Ride Characteristic | MEGABLAST |
|---|
| Softness | Soft and highly cushioned |
| Bounce | Very high |
| Energy Return | Very high |
| Responsiveness | High |
| Stability | Moderate for a maximum-cushion neutral shoe |
| Transition | Rolling and smooth |
| Road Feel | Low to moderate |
| Long-Run Comfort | Excellent |
| Speed Capability | High for a maximum-cushion trainer |
The word that best describes the MEGABLAST is bouncy.
It does not attempt to give the runner a firm, highly connected road sensation. Instead, the shoe places a large amount of energetic foam between the foot and the road and allows that foam to absorb, compress and rebound through each stride.
The Rockered Geometry
The MEGABLAST uses a pronounced rocker geometry to complement its high stack and energetic foam.
The rocker helps the foot transition forward through the gait cycle, particularly when the shoe is loaded under the midfoot and forefoot.
This is important because a highly cushioned shoe can otherwise become cumbersome when the runner increases cadence.
The MEGABLAST's geometry is designed to help prevent that sensation.
The result is a shoe that can transition from:
- Easy running
- Steady running
- Long-distance running
- Progression running
- Faster aerobic running
without requiring the runner to move into a completely different shoe category.
MEGABLAST for Easy Runs
This is one of the shoe's strongest applications.
The combination of maximum cushioning and lightweight construction makes the MEGABLAST particularly effective for everyday easy kilometres.
The substantial midsole helps absorb repeated road impact while the high rebound keeps the ride from becoming dull.
For runners accumulating significant weekly mileage, this can make the MEGABLAST a useful primary training shoe.
MEGABLAST for Recovery Runs
The MEGABLAST is highly suited to recovery running.
Its cushioning provides a protective platform when the legs are tired, while the energetic foam helps prevent the shoe from feeling completely flat.
However, the high stack and pronounced bounce mean it will not suit every runner as a recovery shoe. Some runners prefer a lower, more stable and more controlled platform when fatigued.
