Negative

Gives them toe blisters and sizing up isn't an option.

Mixed

Loves it, but it rips up their pinky toes on longer runs.

Mixed

Significantly more stable than the Topo Specter 3 for them, but the toe box is a problem.

Reddit · r/RunningShoeGeeks · Aug 16, 2026 · summarized

Negative

Very tapered toe box that gives them hot spots on long runs.

Reddit · r/RunningShoeGeeks · Jul 1, 2026 · summarized

Mixed

Loves the foam but it chews up their toes even half a size up.

Reddit · r/RunningShoeGeeks · Jun 27, 2026 · summarized

Mixed

Loves the midsole, but the narrow, low-volume toe box killed their toes after several miles.

Reddit · r/RunningShoeGeeks · Apr 29, 2026 · summarized

Negative

Back in the box after a couple of runs due to pinky-toe blisters from the narrow toebox.

YouTube comment · on Ben Parkes - Road Running Reviews · Mar 30, 2026 · summarized

Negative

Trained 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.

YouTube comment · on Ben Parkes - Road Running Reviews · Mar 29, 2026 · summarized

Mixed

Got 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.

YouTube comment · on Ben Parkes - Road Running Reviews · Mar 27, 2026 · summarized

Positive

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

Reddit · r/RunningShoeGeeks · Mar 2, 2026 · summarized

Mixed

It rubs their pinky toe, making runs over 10K tricky, though they enjoy the feel.

Reddit · r/RunningShoeGeeks · Feb 9, 2026 · summarized

Mixed

A 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.

Reddit · r/RunningShoeGeeks · Dec 14, 2025 · summarized

Negative

Their first tempo half marathon in it destroyed their pinky toes with blisters despite them not having wide toes.

Reddit · r/RunningShoeGeeks · Dec 4, 2025 · summarized

Negative

Two runs in, the narrow toe box gives them big-toe pain that worsens over distance.

Reddit · r/RunningShoeGeeks · Nov 4, 2025 · summarized

Negative

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

YouTube comment · on Ben Parkes · Oct 2, 2025 · summarized

Positive

Took 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.

Reddit · r/RunningShoeGeeks · Sep 30, 2025 · summarized

Negative

Three 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.

Reddit · r/RunningShoeGeeks · Sep 24, 2025 · summarized

Negative

After 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.

YouTube comment · on Ben Parkes · Sep 17, 2025 · summarized

Negative

After 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.

YouTube comment · on Ben Parkes · Sep 16, 2025 · summarized

Mixed

Finds 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.

Reddit · r/RunningShoeGeeks · Sep 10, 2025 · summarized

Mixed

In UK 9.5 the Megablast fit is less comfortable than hoped, snug around the little toe.
