Critic consensus
from 11 reviewsThe Asics Megablast is an energetic super trainer celebrated for pairing a massive, bouncy foam stack with remarkably low weight. Reviewers consider it an exceptionally versatile option for everything from daily mileage to uptempo workouts and marathon efforts, though its premium price is steep. It best suits neutral runners seeking a lively, highly cushioned ride without a carbon plate.

A shoe earns a tag as soon as one reviewer recommends it for that kind of run; the count shows how many agree. Mentions include synonyms, so “recovery”, “zone 2” and “conversational” all count toward Easy.

For the right runner, the Megablast could be the best running shoe perhaps ever made given its exceptional weight, comfort, and versatility.
