ASICS Superblast 2 Reviews

Two pairs of Superblast 2 in, they set their marathon PR in a pair bought three days before the race.

Likes how versatile the Superblast 2 is across paces, from slow recovery runs up to their marathon pace, where it still feels good.

1,050 km on one Superblast 2 and 240 km on a second: it carried a new runner through marathon prep, shining on long runs mixing MP and easy pace, with a slightly wide toe box they came to appreciate.

At 600 miles the Superblast 2 is still going strong after recovery runs, Pfitz long runs, MP work, tempos and their first marathon; only a bit too much stack for VO2max work.

A half-marathon runner who ran about 400 miles (600 km) in roughly six weeks, across long runs of 22-32 km, tempo work and some recovery runs. They praise its versatility, grip on wet grass and corners, and how well the sole and foam held up, and call it excellent for long runs. They say it is not built for fast track reps, the 45 mm stack is too tall to race in, the toe box is slightly narrow, the foam lost a little pop, and they found the price and UK availability negatives.

A 6'4", 245 lb runner ran a marathon in the Superblast 2 with no leg pain, unlike earlier halves in the Endorphin Pro 3.

A heavier midfoot striker at 207 miles uses the Superblast 2 for everything and set a half PR: stiff at first, it softened around 40 miles into rebound and stays protective deep into long runs.

A runner calls the Superblast 2 their favourite non-plated long-run shoe for training and marathon racing, keeping their legs fresh.

Loving the same foam as in their favourite race shoe, they ran 100-120 miles in this one, including dirt paths, wet surfaces and snow. They find it a great easy-day and long-run shoe that feels excellent at marathon pace, with no traction problems, a comfy breathable upper and no blisters. They rate the foam only 7/10, find the 45 mm heel clunky and less poppy than the race shoe, say the upper is too cold in 20-degree weather, and would point most runners to an Evo SL or Nimbus instead because of the price.

A smooth, reliable long-run workhorse: soft-but-firm, slightly bouncier than v1, roomy toe box, no hot spots. 250+ miles in and it 'still looks fresh'; one tester says it works for easy days and as a race shoe up to the marathon.

Found it stiff and firm at first and nearly returned it, but it clicked around mile 20–30. It is now the go-to for tempo and long runs, with snappy energy return; too firm for easy and recovery days, where the Novablast 5 is preferred.

Replaced a HOKA Mach 6 with the Superblast 2 and, 250 km in, is happy: stiff at first, comfortable after 100 km, excellent as a daily trainer and long-run shoe and responsive enough for tempo, though clunky for intervals and not enjoyable on recovery days.

Compares the Superblast 2 with the Mizuno Neo Vista: both fantastic smile-on-your-face long-run shoes; the SB2 runs a little short so they sized up half.

Ran a 24-hour, 100+ mile ultra in the Superblast 2 as a road-ultra runner and reviewed how it held up over that distance.

Moved from the Endorphin Speed 3 to the Superblast 2 and, about 100 miles in, finds it just okay: stiff, clunky at slow paces, with little energy return unless they pick up the pace. It does shine on long runs and when their legs are tired, so they are keeping it.

A 76 kg runner who found the Superblast 2 firmer than expected; it needed 70-80 km to break in and feels like a brick at slow paces and for heel striking, and they picked up ITB trouble while adapting. Later ran a marathon in it and it was perfect, comfortable for four hours with fresh legs.

After 200 miles, a 190lb runner says the Superblast 2 barely looks used, has a plusher upper and more responsive foam than v1, and is their go-to 90% of the time.

Saves it for long runs, with easy miles in the Novablast 4. Took time to find their groove: on hilly routes the heel feels clunky and makes good downhill form difficult.

After long runs in the Superblast 2 their feet still feel great, so they recover and run again sooner.

About 100 miles in, finds the Superblast 2 as good or slightly better than the first version for long runs with pace work, and it handled 5:50/mile repeats as long as turns weren't sharp. Prefers the Boston 12 for intervals but says the Superblast 2 can do it all.
