Adidas Adizero Evo SL Woven vs ASICS Mega Blast: Which Trainer Deserves Your Miles?

Introduction

If you are shopping for a new daily trainer, speed trainer, or super trainer, this is a comparison worth paying attention to. The Adidas Adizero Evo SL Woven has been getting a second wave of attention thanks to a revised, far better upper and a slightly softer foam feel, while the ASICS Mega Blast remains one of the most beloved trainers of the past few years.

One is a $150 trainer with race foam and geometry that nudges you toward faster paces. The other is a pricier, more stacked shoe with what is arguably the most advanced training foam on the market right now. They overlap, but they are not trying to do the same job.

Quick Specs

The Mega Blast is the taller shoe of the two, coming in around 45 mm in the heel. Its FF Turbo Squared foam is a tweaked, firmer and more stable version of ASICS’ race foam tuned for training. The Evo SL Woven sits lower to the ground at roughly 37 mm in the heel with a large rocker, and uses Light Strike Pro foam.

A note on the Woven specifically: the pair tested here was made in Indonesia, and the foam in this version feels noticeably softer and more comfortable than earlier standard versions made in China and Vietnam. Where your pair is made may matter.

Fit and Upper: A Clear Win for the Evo SL Woven

The woven upper is the headline upgrade. Adidas went from having one of the worst uppers in the running shoe market to one of the best. The material sits on top of the foot with no bunching or odd pressure points, the lockdown is secure, and there is plenty of padding around the heel. It is genuinely dialed.

The Mega Blast’s upper is its one real downside. It is not bad, but it feels tight out of the box, then stretches to feel almost loose after break-in. If ASICS ever updates this shoe, a better upper would be the obvious move, because the midsole leaves little room for improvement.

Geometry and Ride: Two Very Different Philosophies

The Evo SL Woven is all about geometry. The platform is flat through the rearfoot and then rolls into a big rocker that covers roughly 60% of the shoe, creating a defined sweet spot in the forefoot. It wants you to land in a specific zone and push off there, and every run in it tends to force a quicker pace. That is not a bad thing if your goal is lifting your maintenance paces, but some runners find the geometry is not quite what they want, and the experience can vary from run to run.

The Mega Blast lets you land anywhere you want. Smash the heel, land flat, get up on the forefoot and rip 400s. With far more foam underfoot, it is a better long run shoe, a better relaxed-miles shoe, and more versatile overall. The foam itself is incredibly energetic and bouncy, like a racehorse chomping at the bit, whereas the Evo SL relies more on geometry than foam character to get you moving.

Cold Weather Behavior

One practical point in both shoes’ favor: neither foam bricks up in the cold. Both were run in genuinely frigid conditions, down around -4 European (19F), and both kept their bounce and smoothness. That is one of the real benefits of modern race-foam trainers and super trainers.

On grip, though, the ASICS takes it. The Continental rubber on the Evo SL is legendary in name, but on actual ice it offered essentially no traction, and other brands’ rubber compounds have caught up. The Mega Blast’s outsole lugs handled cold, sketchy surfaces noticeably better, making it the safer winter pick of the two.

Foam Quality: The Mega Blast’s Biggest Advantage

The Light Strike Pro in the Evo SL is a good foam, but it sits one tier below the top-performing super trainer compounds, and the ride can feel inconsistent depending on the run. The Mega Blast’s FF Turbo Squared is a modified version of ASICS’ race shoe foam, nearly as energetic but tuned for training. It is arguably the most advanced training foam available right now.

Community opinion on the Evo SL is split, roughly 60/40 between people who think it is the greatest shoe ever made and people who find it a flat shoe with great geometry but a somewhat lifeless foam at some paces. The woven version with its softer foam seems to be winning over more people from the skeptical camp, and the same pattern showed up in extended testing here.

Durability Notes

The Mega Blast was taken up to around 300 miles, and the picture there is worth knowing. The more it breaks in, the softer the foam gets and the more the upper stretches, which may make the shoe slightly less stable over time. The Evo SL Woven is still early in its mileage, with plans to push it toward 100 miles.

How to Choose Between Them

Here is the simplest decision framework. If you want long run capability, the craziest bounce, more protection underfoot, more versatility, better raw speed, or better winter grip, the Mega Blast is the pick. It is the mileage racker and the stacker.

If you want the best deal, a shoe that encourages faster daily running, or you are a forefoot striker who mostly uses the front of the platform, the Evo SL Woven makes sense. It also wins if the upper is your priority. For shorter runs of 45 minutes or less, you could get away with the Evo SL comfortably.

At $150, the Evo SL is priced like a standard daily trainer while delivering race foam and genuinely fast geometry. That is a strong value, though the market is catching up. The Mega Blast costs significantly more, but what it delivers for that price, a race-shoe-like foam with more stack and no plate, justifies the gap. One thing neither shoe is good for: walking. If you need a walking shoe, look elsewhere.

Conclusion

The Mega Blast remains the winner of this comparison. It is the more complete shoe: better foam, better grip, more stack, and more versatility across paces and run types. But the Evo SL Woven is a highly capable trainer in its own right. With the new upper and softer foam, it has gone from a shoe that was hard to recommend to one that is genuinely enjoyable for fast daily miles and even hill sprints. Buy the Mega Blast if you want the best and your budget allows it. Buy the Evo SL Woven if you want maximum value in a fast daily trainer.
