NegativeTrained about 50 miles in them without issues, then raced a half marathon and damaged both big toenails so badly they came off weeks later, which they blame on the snug toe box.

MixedGot two black toenails from the toe box in their usual ASICS size, but considers it the best shoe they have owned, so they sized up and now run all marathon workouts in it without issues.

PositiveAt 740 km their pair is still perfect. The narrow feel eased after about 70 km, though the front remains quite narrow.

MixedA 45-65 mpw midfoot striker at 600 km finds the Megablast one of their most versatile shoes, grippy, stable on turns and light with great energy return and little outsole wear, but the low-volume tapered toe box left bleeding toes on a 38 km run, so they keep it under 25 km.

NegativeThe Megablast forefoot is snug and causes big-toe discomfort late in longer runs.

PositiveTook it on a 14 km run on day one and grinned the whole way; it is a bit snug in the forefoot, but they hope it loosens before their first marathon.

NegativeThree runs in, the Megablast toe box is tight; on the first run they changed shoes at 10k due to a blister at the big-toe knuckle.

NegativeAfter more than 50 pairs of Asics, the Megablast was the first that didn't fit: the toe box was crazy tight in their usual size, so they returned it.

NegativeAfter three trouble-free pairs of Superblast 2, got a pinky-toe blister on the first run in the Megablast; half a size up still blistered both pinky toes within five miles, so they cut holes in the upper.

MixedFinds the Megablast quite narrow, which makes it uncomfortable to wear for long, and wishes ASICS offered wider sizes; otherwise it would be a great shoe.

MixedIn UK 9.5 the Megablast fit is less comfortable than hoped, snug around the little toe.
Most runners find the Megablast bouncy, responsive and very durable, with plenty of life left after hundreds of miles and use as an all-round trainer. The narrow, low toe box is the main complaint, causing blisters, especially on the pinky toes, and lockdown is hard for some.
