ASICS Magic Speed 2 vs Magic Speed 3: Which Carbon-Plated Trainer Fits Your Running?

Introduction

The ASICS Magic Speed 2 and Magic Speed 3 share a name, a carbon-plated design, and a 7 millimeter heel drop, but they are surprisingly different shoes to run in. The Magic Speed 3 adds a second layer of FF Blast foam, a taller stack, a lighter upper, and a full-length carbon fiber plate that makes it bouncier and snappier. The Magic Speed 2 stays firmer, with a TPU carbon-plated construction that favors shorter, sharper efforts. Which one suits you depends mostly on how you plan to use it.

Weight and Midsole: Where the Biggest Changes Live

The Magic Speed 3 is the lighter of the two. Listed at around 7.8 ounces, it comes in noticeably under the Magic Speed 2’s 8.1 ounce listed weight, with a real-world drop of roughly half an ounce in comparable sizes. A good part of that saving comes from the reworked upper, but the midsole plays a role too.

Underfoot, the stack heights diverge. The Magic Speed 3 runs a 36/29 millimeter stack with two layers of FF Blast foam, while the Magic Speed 2 sits at 34/27 with a single firmer layer. The heel-to-toe drop stays at 7 millimeters on both. The extra foam in version 3 compresses more and gives a distinctly more cushioned, bouncy feel underfoot, while version 2 feels noticeably firmer.

Upper and Fit: Snugger and Slightly Short in Version 3

ASICS changed the upper considerably between versions. The Magic Speed 2 has a bit more volume in the toe box, still slightly pointed but not uncomfortable. The Magic Speed 3 uses a much lighter upper that fits roughly half a size short, similar in feel to the ASICS Megablast. The heel area stays light on both, with a touch more stiffness at the rear foot on version 3.

The practical advice is simple: if you want the Magic Speed 3 for training and longer runs, go up half a size. If it is for fast days and racing and you are comfortable with a slightly shorter fit, staying true to size works fine. Both uppers are very secure, which is a genuine strength shared by the pair.

Ride Feel: Bouncy versus Firm

This is where the two shoes could not be more different. The Magic Speed 3’s double layer of FF Blast foam plus its full-length carbon fiber plate creates a far bouncier, snappier ride. It has proven strong for intervals, fartleks, tempo runs, and even longer tempos, and it handled easy runs acceptably well, though that is not its best role. Once you learn to lean into the bounce, it delivers some genuinely fast interval sessions.

The Magic Speed 2 rides firmer, with a less stiff TPU carbon-plated construction. It feels best suited to shorter efforts like strides rather than sustained fast work. It is not a bad shoe, just a narrower one in what it does well.

It is worth noting that neither is a true super shoe, since the foam does not reach that top-tier level of aggression. The foam is still very good, though, which makes the Magic Speed 3 a strong pick for runners who want a carbon-plated shoe with bounce but without maximum aggression.

Which One Should You Buy?

At $160, the Magic Speed 3 is a compelling option, and for many runners it will become a go-to workout shoe. Racing duties may still belong to a super shoe, but for runners who do not get along well with super shoes, the Magic Speed 3 is a very good alternative.

If you enjoy a firmer ride and mostly want a shoe for shorter, sharper efforts, the Magic Speed 2 still has a place. If you want more bounce, more cushion, and a shoe that can carry everything from intervals to long tempos, the Magic Speed 3 is the clearer pick.

Conclusion

The Magic Speed 3 takes the formula further: lighter, bouncier, better cushioned, and more versatile, with a half-size-short fit to plan around. The Magic Speed 2 remains a firmer, more focused option for short fast efforts. Match the shoe to your training style and sizing, and either can earn a spot in the rotation.
