Adidas Supernova Prima 2 vs Asics Superblast 2:
Which to Choose

September 5, 2026 | updated at September 9, 2026

Verdict

If your training is built around comfortable, steady mileage and you want a stable, forgiving shoe that never surprises you, choose the Supernova Prima 2. If you run faster — tempo efforts, marathon-pace long runs, or race day itself — and want a plateless shoe that keeps up with the effort through foam energy alone, the Superblast 2 is the stronger choice. The deciding factor is pace: the two shoes' sweet spots barely overlap, and matching the shoe to how fast you actually run will matter more than any other consideration.

Who Should Choose Each Shoe

Choose

Adidas Supernova Prima 2

The Prima 2 is the pick for recreational runners who want one dependable shoe for daily miles and long runs without worrying about managing a tall, lively stack. It particularly suits neutral-to-mild overpronators who benefit from the Dreamstrings-assisted stability and who run most of their miles in the 5:00–6:30 min/km range. If consistency, predictability, and a settled, comfortable ride across easy and long efforts matter more than energy return or race-day versatility, this is the shoe.

Choose

Asics Superblast 2

The Superblast 2 is built for intermediate-to-experienced runners who want a single shoe capable of handling tempo sessions, uptempo long runs, and marathon race day without buying a dedicated carbon racer. Neutral runners who regularly train at 4:00–5:00 min/km and want maximum cushioning without sacrificing snap will get the most from the PEBA foam's energy return at pace. It's a poor match for runners who do most of their mileage at recovery shuffle speed, where the tall, lively stack offers little advantage and the neutral platform provides no pronation support.

Head-to-Head

**Cushioning and stack height:** Both shoes deliver generous underfoot protection, but the Superblast 2 goes substantially taller — 45mm in the heel versus 37mm in the Prima 2's heel, a difference you feel immediately. The Prima 2's Boost-based midsole is soft and protective without ever feeling excessive; the Superblast 2's dual-layer FF Turbo Plus over FF Blast Plus Eco stack is deep enough that it can feel slightly tippy at a slow shuffle until you find your rhythm at pace.

**Foam character and responsiveness:** This is where the two shoes diverge most clearly. The Prima 2's Boost foam gives a warm, rounded energy return — cushioned and lively but controlled, without the springy rebound of newer superfoams. The Superblast 2 runs on a PEBA-blend compound that compresses deeply and snaps back with noticeably more energy; it earns a responsiveness rating of 5/6 versus the Prima 2's 4/6, and the difference is tangible when you lift the effort.

**Pace and use case:** The Prima 2 is optimized for 5:00–6:00 min/km (about 8:00–9:40 min/mile) and suits steady base miles, easy days, and unhurried long runs. The Superblast 2 operates in a faster band — 3:50–4:40 min/km (roughly 6:10–7:30 min/mile) — and is genuinely comfortable holding marathon race pace or a harder long run. Neither carries a plate, so neither delivers the snappy toe-off of a carbon racer, but the Superblast 2 comes far closer to that territory on foam alone.

**Stability:** The Prima 2 is the more stable shoe by design. Its Dreamstrings TPU cords wrap the foot and steady lateral movement, earning a stability rating of 5/6 with a stable-neutral support classification. The Superblast 2 compensates for its tall, neutral stack with a widened midsole and extended heel geometry — enough to keep most neutral runners grounded — but it rates 4/6 and is not intended for overpronators.

**Weight:** The Superblast 2 weighs approximately 248g in a US men's 9, while the Prima 2 comes in at 264g for the same size. That 16g gap is modest but meaningful for runners racing or doing uptempo work in the Superblast 2, and it's especially notable given the Superblast 2 carries more foam volume.
