If you’ve ever stood in front of a wall of ASICS shoes wondering what actually separates the Novablast, Superblast, Megablast, or Sonicblast, you’re not alone. The names sound similar, but each model is designed to deliver a very different running experience.
Add the Metaspeed Sky and Edge into the mix, and you’re looking at ASICS’ full performance lineup, engineered around how runners move, absorb impact, and generate speed.
This guide breaks it down simply, so you can choose the shoe that actually matches how you run, not just what’s popular.
The “Blast” Family: One Platform, Four Distinct Rides
At the core of the Blast lineup is FF BLAST™ cushioning, a lightweight foam designed to deliver both softness and energy return. But each model adjusts how that foam behaves, changing the feel underfoot, the level of protection, and how responsive the ride is.
Think of this lineup as a spectrum:
- Softer and more protective on one end
- Lighter and more responsive on the other
ASICS Novablast 5: The Everyday All-Rounder
The Novablast 5 is built for consistency. It’s the kind of shoe you can rely on day after day, whether you’re heading out for an easy run or building steady weekly mileage.
The FF BLAST™ MAX cushioning softens impact without feeling overly soft or unstable. There’s a noticeable bounce underfoot, helped by the trampoline-inspired outsole, which adds a bit of lift to each step. The updated jacquard mesh upper improves breathability and creates a more secure, adaptable fit.
This balance of comfort and responsiveness is what makes the Novablast stand out, it doesn’t overcomplicate things, it just works.
Best for: Daily mileage, easy to moderate runs, and runners who want a reliable, energetic feel without switching shoes.
ASICS Sonicblast: Light, Fast, and Adaptable
The Sonicblast is designed for runners who want versatility without compromise.
Its dual-foam setup combines FF BLAST™ MAX for cushioning and FF TURBO²™ for responsiveness. The addition of the ASTROPLATE™ helps guide forward motion, giving the shoe a smoother, more efficient transition from landing to toe-off.
What you get is a shoe that can handle a range of efforts, from steady runs to faster sessions, without feeling out of place in either.
Best for: Tempo runs, mixed-pace workouts, and runners who prefer one shoe that can cover multiple types of training.
ASICS Superblast 3: High-Energy Training, No Plate Required
The Superblast 3 pushes performance further without stepping into full race-day territory.
By combining FF BLAST™ PLUS with brand new FF LEAP™, a foam typically reserved for elite racing shoes, it delivers a lightweight, highly responsive ride. The energy return is noticeable, especially as you pick up the pace, making longer or faster runs feel more efficient.
Despite the performance focus, it remains stable and comfortable enough for regular use, which is what sets it apart from more aggressive options.
Best for: Faster training days, long steady efforts, and runners who want a race-like feel in a training shoe.
ASICS Megablast: Maximum Cushion, Maximum Protection
The Megablast is built for runners who prioritize comfort over long distances, but still want energy return.
Its FF TURBO™ SQUARED foam delivers a soft yet lively ride that helps reduce impact over time. The wider base adds stability, while the ASICSGRIP™ outsole provides reliable traction across different surfaces.
What makes the Megablast stand out is how it balances cushioning and bounce, you’re protected from the ground, but you’re not disconnected from it.
Best for: Long runs, recovery days, and runners looking for maximum cushioning without a sluggish feel.
The Metaspeed Series: Speed, Built Around You
While the Blast family focuses on training, the Metaspeed series is built for performance. These are ASICS’ carbon-plated shoes, but what makes them different is how they’re designed around running style, not just speed.
Metaspeed Sky Tokyo: Built for Stride Length
The Metaspeed Sky Tokyo is designed for runners who increase speed by covering more ground with each step.
The combination of the brand new FF LEAP™ foam underneath a flatter, wider carbon plate creates vertical propulsion for a longer stride extension on race day. The Metaspeed Sky Tokyo is a shoe that rewards powerful, longer strides.
Best for: Runners who naturally lengthen their stride as they speed up and want to maximize efficiency with each step.
Metaspeed Edge Tokyo: Built for Cadence
The Metaspeed Edge Tokyo is tuned for runners who increase speed by turning over faster.
In contrast to the Sky, the Edge Tokyo places its FF LEAP™ foam overtop of the carbon plate which itself features a much steeper forward angle, creating a curved geometry that facilitates forward propulsion for quicker transitions and a higher cadence. The Metaspeed Edge Tokyo feels more controlled and precise, especially at higher RPM.
Best for: Runners with a faster cadence who want a shoe that supports quick, efficient turnover.

The key takeaway is simple: these shoes aren’t competing with each other, they’re solving different problems.
