The Megablast is my tempo shoe. That’s the simplest way to say it. If I’ve got a workout on the schedule — progression run, threshold work, tempo — these are what I’m lacing up. They hold speed better than my easy-day shoes, and the cushion’s substantial enough that I’m not beat up the next day.
Now, will I pull them out on an easy day? Sometimes. If I’m feeling lazy or the rest of the rotation is in the wash, the cushion’s there and it’s a fine easy-day shoe. But that’s not the slot they’re in. They’re a tempo shoe that happens to be comfortable enough to slum it on a recovery day.
From the training log on Roman’s first birthday: “Florida in late May is the soup. 75 degrees, 94% humidity. The ASICS Megablast were on. Cushioned enough that I’m not fighting the road.” Five miles, forty-five minutes, calf quiet. That was an easy effort day — the kind of day they handle but aren’t built for. Full run report here.
What they’re not: a carbon race shoe. If you want something to PR in, look at the Alphafly or Vaporfly conversation. The Megablast is honest training kit — the shoe that carries the build, not the one that crosses the finish line.
Worth noting: ASICS sells these direct and that’s where I link. Amazon has them too but the direct site usually has size availability and you’re not paying a markup for the privilege. One fewer middleman.
If your tempo days have been on whatever shoe you grab — these are worth the upgrade. I’m going into the Indianapolis Monumental build with them as my tempo shoe and I don’t see that changing.
