Race-Day Foam. Every-Day Training.

The first ASICS Superblast rewrote what a training shoe could be. No plate, no compromises — just a towering stack of responsive foam that could handle easy miles and fast efforts with equal confidence. Runners noticed. Then everyone noticed. Then it sold out everywhere.

The Superblast 3 is the version that earns that reputation all over again.

ASICS made one decisive move for v3: bringing FF Leap — the most advanced foam in their racing fleet, found in the Metaspeed Tokyo and Metaspeed Ray super shoes — into an everyday trainer. The result is a shoe that delivers a 15.4 percent increase in energy return compared to the Superblast 2, with a 1.5mm taller stack height and yet 10 grams less weight. More cushion. More response. Less shoe to carry.

This is the one-shoe rotation option for runners who refuse to settle.

The Technology

FF Leap + FF Blast Plus — The Dual-Layer Midsole

The Superblast 3 midsole is an exercise in intelligent engineering. FF Leap is 33% lighter and 13% more responsive than FF Blast, while still offering enough cushioning for daily training. It forms the dominant upper layer of the midsole — delivering the softness, bounce, and energy return associated with ASICS' fastest race shoes.

Beneath it, a firm 10mm lower layer of FF Blast Plus with a rise at the medial midfoot keeps any mush or instability in check — grounding the ride and giving runners a reliable, composed platform even as the upper foam gives back energy with every stride.

Diamond Forefoot Bounce Pod — Engineered Propulsion

A diamond-shaped design channeled into the top of the FF Leap layer, positioned just behind the toes, allows the foam to compress more independently in that zone — creating a more dynamic and responsive toe-off. It's a small detail that shows up in a big way when you decide to push the pace.

Engineered Woven Upper — Structured and Breathable

The engineered woven mesh upper is stiffer and surprisingly structured due to interwoven overlays, with a fit that is wider than prior versions and slightly higher volume — correcting the cramped toe box that affected earlier Superblast models. A redesigned lacing system with cord loops rather than traditional eyelets allows for a personalized, secure lockdown without the need to overtighten.

Who This Shoe Is For

• Runners who want one versatile shoe that handles easy miles, long runs, tempo work, and race day
• Athletes seeking carbon-plate performance levels without a carbon plate — or the rigidity that comes with one
• Long-distance runners who want maximum cushioning that still gives back energy, not just absorbs it
• Runners who put in high weekly mileage and need a shoe that stays lively deep into training blocks

Specs

Fit note: Fits true to size. The v3 upper is wider and slightly higher volume than prior Superblast versions — runners who sized down in v1 or v2 should return to their true size.
