ASICS Mega Blast Review: A Lighter, Bouncier Super Trainer

Introduction

The ASICS Mega Blast is the newest addition to the Blast line, a family that has quietly become one of ASICS’ strongest running franchises. It arrives as a lightweight, high-stack super trainer built around a brand-new foam, and it sits in a very similar lane to the beloved Super Blast. With a $225 price tag and plenty of cheaper rivals closing in, the question is whether the upgrades justify the jump.

Upper and Fit

The upper is very light and highly breathable, with a yarn construction that feels closer to a race day shoe than a daily trainer, though with a bit more padding in the heel. The sawtooth laces with cammy beads hold well, and the tongue is gusseted on both sides for a secure feel.

Fit is true to size with no hot spots over long runs, but the heel counter and collar are the weak point. There is some gaping around the heel when you look down, and the fit there leans heavily on the interior pillow padding. It sits somewhere between the Super Blast and a true race day fit.

Midsole: Flight Foam Turbo Squared

The midsole uses a completely new foam called Flight Foam Turbo Squared. It is an aliphatic TPU (ATPU), a material trending across the industry because of its durability and rebound. ASICS claims it is 33% more bouncy than the previous Turbo foam and about 10% lighter.

The stack is substantial: 45mm in the heel, 37mm in the forefoot, an 8mm drop. At 8.7 to 8.8 oz (249g) in a men’s 10.5, it is genuinely light for a daily trainer, coming in around the same weight the Super Blast hit in a men’s 9.

Ride and On-Run Feel

On the run, the Mega Blast delivers plenty of cushion and a fun, bouncy ride that can go any distance. On a 16-mile long run with the pace picked up at the end, the combination of light weight and midsole bounce felt great. Interestingly, heel striking brings out the biggest bounce, while midfoot running feels more controlled and stable.

Compared to the Super Blast, which could feel like you sink into it a bit and were better suited to holding a pace than pushing it, the Mega Blast offers more punch when you want to move. It reads like a successor in spirit: an improvement in many ways, especially in weight and energy return.

The Blocky Factor

The main design criticism carries over from the Super Blast: the wide platform can feel a bit blocky underfoot, which limits agility when cornering or trying to go fast. That wide platform is also where the stability comes from, and this shoe is far more stable than, say, the Nova Blast. If you prefer a sleeker feel, the Sonic Blast may suit you better.

Durability and Value

ATPU foam should hold up for hundreds of miles, and the outsole offers solid traction with plenty of exposed foam that showed minimal wear after roughly 30 miles. The foam is not overly squishy, so it resists compressing to nothing, and a little break-in may even improve the ride.

The catch is price. At $225, the Mega Blast sits well above competitors in the $140-160 range that also use lightweight, resilient foams. The counterargument is that this platform may hold up longer and provide a firmer, more durable base than some cheaper options.

Buying Advice

If you want an unplated race day-adjacent shoe or a lightweight do-it-all trainer, the Mega Blast is a strong pick. ASICS says the Super Blast will remain in the lineup as the long run option with a bit more stability, so the Mega Blast makes most sense for runners who prioritize lightness, bounce, and speed over maximum cushion and support. Color options run wild and bright, though a clean triple white with a pearlized midsole is available for quieter tastes.

Conclusion

The Mega Blast is a great shoe that functions as an improvement on the Super Blast for many use cases: lighter, bouncier, and fun across distances. Whether it earns a slot in your rotation will come down to taste and budget, but for weight, durability, and cushioning, it is among the best in its class.
