Overview

The ASICS Megablast is ASICS' max-stacked super trainer—pushing the boundaries of bounce and cushioning to create the most responsive Blast shoe yet. With a massive 47mm heel stack and FF BLAST TURBO foam, the Megablast delivers an incredibly springy ride that feels almost otherworldly.

This is ASICS taking the Blast concept to its logical extreme. The Megablast isn't subtle—it's a shoe that wants you to feel every bit of its energy-returning foam on every stride.

What It's Known For

The Megablast's 47mm heel stack is among the highest available in running shoes—and it's all responsive FF BLAST TURBO foam. This creates an incredibly bouncy sensation that makes the shoe feel alive and eager to propel you forward.

Despite the massive stack, the Megablast weighs just 8.5oz. This defies expectations and makes the shoe feel surprisingly nimble given its cushioning volume.
