Asics Superblast 2

Who Are Asics Superblast 2 For?

These are for the intermediate-to-experienced runner who wants one shoe to cover tempo sessions, uptempo long runs, and even race day without buying a dedicated carbon racer. It rewards runners who like to push the pace but still want protection under a tall stack — not the ideal pick if you mainly jog easy recovery miles, where its lively foam feels slightly wasted.

Feelings and Experience

Underfoot it feels tall, soft, and springy, with a PEBA-blend foam that compresses generously then rebounds with genuine energy as you roll forward. The ride comes alive once you lift the pace; at a slow shuffle the height can feel a touch tippy until you settle in. Transitions are smooth and rolling rather than snappy, since there's no plate forcing the tempo — the bounce comes from the foam itself.

Performance Specs

• Drop: 8mm heel-to-toe offset — a moderate offset that suits midfoot and heel strikers alike

• Cushioning: maximum, FF Turbo Plus over FF Blast Plus Eco — deep, plush protection

• Responsiveness: high — driven purely by the PEBA superfoam, no plate

• Stability: moderately good for a tall shoe — neutral support on an unusually wide, sculpted base

• Pace: Optimal for 3:50–4:40 min/km (6:10–7:30 min/mile)

Best Distances and Maximum Speed

It genuinely excels from 10K through the half and full marathon, with the half marathon as its sweet spot. Push it to its fastest effective zone of roughly 3:40–4:00 min/km (5:54–6:26 min/mile) and the foam works at its best; below that, a plated racer will serve you better.

Technologies and Materials

The midsole pairs a top layer of FF Turbo Plus PEBA foam over FF Blast Plus Eco for a stack near 45mm with no plate. A breathable engineered woven upper and strategic AsicsGrip outsole rubber round it out. At roughly 248g (US men's 9) it's remarkably light for its size, though that thin outsole coverage means durability is a fair trade-off.
