ASICS Superblast 3 Running Shoes

Key Specs

What's Changed from the Superblast 2

The Superblast 3 introduces several meaningful updates over the Superblast 2.

Midsole: The addition of FF LEAP™ foam in the upper layer creates a softer, bouncier ride. FF BLAST™ PLUS is retained in the base layer for stability and ground feel. The result is a dual-density setup that's noticeably more energetic than the single-density midsole in version 2.

Outsole: A trampoline-inspired pod under the forefoot boosts energy return at toe-off. The Superblast 3 keeps the smooth cushioning of the 2 but adds a more noticeable rebound when you roll through your stride.

Weight: Reduced to approximately 237–239g, down from around 255g in the Superblast 2. The lighter build is noticeable on foot, particularly over longer efforts.

Stack Height: Increased to 46.5mm heel / 38.5mm forefoot (8mm drop), up from 45mm/37mm in the Superblast 2. More cushioning underfoot without a noticeable change in ride height feel.

Platform: Subtly widened through the midfoot for added stability, compensating for the softer midsole compound.

Upper: Updated engineered woven mesh with improved midfoot support via a redesigned eyestay. Breathable, secure, and very similar fit profile to the Superblast 2.

Break-in: Unlike previous versions, the Superblast 3 feels dialled from the first run with no notable break-in period.

Sizing & Fit

The Superblast 3 fits true to size for most runners. The fit profile is very similar to the Superblast 2, so if you had a size that worked in version 2, the same size should work here.

This is a unisex shoe sold in men's sizing. Women should order 1.5 sizes below their normal running shoe size. For example, if your normal size is a Women's 8, order a 6.5.

The upper holds the foot securely through the midfoot with no pressure points or hotspots reported by our testing team across 100km of use. The step-in feel is comfortable straight away.

How It Compares

Superblast 3 vs ASICS Megablast

The Superblast 3's shift toward a softer, bouncier ride creates clearer separation from the Megablast in the ASICS lineup. The Superblast now sits more firmly in the everyday cushioned trainer role, while the Megablast serves as the faster, firmer option for longer efforts at higher intensities. Runners who previously used the Superblast 2 for faster long runs may find the Megablast now fills that role more naturally. See our full ASICS Megablast breakdown.

Superblast 3 vs Gel-Nimbus

The Superblast 3 offers a similar level of protection and cushioning to the Gel-Nimbus, but with a more energetic, engaging ride character. Runners who find the Nimbus too passive may prefer the Superblast's added bounce and liveliness. See our full ASICS Gel-Nimbus breakdown.

Superblast 3 vs Novablast

The Superblast 3 feels more stable and composed than the Novablast, particularly on longer runs or when fatigued. It offers a more controlled platform while still delivering plenty of cushioning and energy return. See our full ASICS Novablast breakdown.

Who Should Buy the Superblast 3

The Superblast 3 is best suited for runners who want a single versatile trainer that handles easy runs, long runs, and steady efforts. If you're looking for a max-cushioned shoe that's still lively and engaging, this is a strong option.

If you liked the Superblast 2, this will feel familiar — just softer, with more bounce, and a slightly different purpose. The ride has shifted toward comfort and everyday versatility rather than faster-paced long runs.

If you're new to the Superblast range, it's one of the most complete do-it-all trainers available — a genuine one-shoe option for runners who don't want to overthink their rotation.
