ASICS Magic Speed 5 Review: Carbon Trainer for Sub-3 Runners

Released in December 2025, the ASICS Magic Speed 5 represents a dramatic shift for the series — going from a stiff, traditional carbon trainer to something that feels almost indistinguishable from a race shoe.

The Magic Speed line sits one tier below ASICS’s flagship MetaSpeed carbon shoe series, offering high-performance carbon plate technology at a more accessible level.

The upgrades from the previous model looked genuinely exciting, so I picked up a pair right at launch.

About 20% lighter than its predecessor, the Magic Speed 5 carries near-racing-shoe specs. It’s a far more versatile shoe that can genuinely handle almost any type of training — a completely different shoe from the Magic Speed 4.

In my opinion, this is the most enjoyable Magic Speed yet — though the target runner has shifted slightly upward in ability level. One thing to be aware of: the sizing runs small.

In this review, I’ll cover the ride feel, sizing, and which runners and training scenarios this shoe suits best.

By the end, you’ll know whether the ASICS Magic Speed 5 belongs in your rotation.

Why I Bought the ASICS Magic Speed 5

I previously owned the Magic Speed 4 — a great shoe with strong propulsion that was easy to run in. But despite having a carbon plate, the sole itself felt notably stiff, and I never really found it comfortable.

The Superblast 2 gave me a similar feeling. With almost no flex in the sole, your foot feels almost locked in place.

I ended up passing on both the Superblast 2 and the Magic Speed 4 after wearing them a few times, which left me without a training shoe that could grip well on wet roads.

My only remaining option was the PUMA DEVIATE NITRO ELITE 3 that I’d been using as a trainer, but it already had around 700 km on it and was approaching the end of its life.

I was looking for a high-traction shoe I could train in hard. I already had the Adidas Adizero EVO SL and the New Balance FuelCell Rebel v5, but neither delivers great traction.

The Magic Speed 5 uses ASICS GRIP on the outsole and dropped significantly in weight. The near-race-shoe specs gave me slight pause, but my curiosity won out — I bought a pair immediately.

Running Performance Review

Here’s how the Magic Speed 5 felt on the run.

I tested it across a range of paces: moderate runs from 8:03/mile (5:00/km) to 6:26/mile (4:00/km), and lactate threshold intensity sessions from 6:10/mile (3:50/km) to 5:22/mile (3:20/km).

Walking around in them first, the rocker-style roll-forward feel you get from the MetaSpeed series is more subdued — the sole feels relatively flat in comparison.

Jumping and bounding in place, the not-too-thick sole and firm-but-not-harsh cushioning made it feel light and responsive — easy to get off the ground.

Starting out at an easy pace, the ground feel is immediately different from its predecessor. The Magic Speed 4 had a midsole over 40 mm with almost no flex, so you couldn’t feel much underfoot. The Magic Speed 5 has a noticeably softer ground feel.

That said, it’s not soft in any mushy way. I suspect this is largely due to the FF BLAST PLUS foam placed on the ground-contact side of the midsole.

As I pushed the pace, the bounce became more pronounced. Rather than rolling over a stiff sole, it rewards the kind of stride you’d use in a race shoe — compressing the cushion and loading up for rebound.

The overall feel edges toward a high-end racing shoe — light, bouncy, and genuinely comfortable at pace.

Pushing closer to 6:26/mile, the comfort is almost indistinguishable from a race shoe. However, comparing effort-to-pace, it doesn’t quite match high-end shoes like the MetaSpeed series for raw speed.

I also ran some strides at around 4:50/mile (3:00/km). The response is snappy, and speed comes easily. It suits a quick-turnover style rather than one where you load up each stride.

Race-Level Performance in a Daily Trainer

The Magic Speed 5 now closely matches the specs and ride feel of a race shoe, while still providing enough landing stability to work well as a daily trainer.

For my own races, I would always reach for the MetaSpeed series — it’s a clear performance step up, and there’s no compelling reason to race in the Magic Speed 5 when you have that option.

For training, though, I expect to use the Magic Speed 5 often. High-end carbon shoes can feel unstable underfoot and tend to pull too much out of you for everyday use — the Magic Speed 5 sits in a better balance for training workloads.

As a full marathon race shoe, the Magic Speed 5 seems well-suited to runners targeting sub-3 hours down to sub-2:50.

In my opinion, runners targeting around sub-3 can’t fully extract the performance a shoe like the MetaSpeed Edge Tokyo offers — and in the late stages of a race when fatigue sets in, the instability of a high-end carbon shoe could actually hurt performance.

For runners in the sub-3 to sub-2:50 range, racing in the Magic Speed 5 is a legitimate option. The spec upgrade is substantial enough to recommend it as a race shoe.

Design and Upper: Built for Speed

The Magic Speed 5’s construction has shifted dramatically. Previous versions had a solid, clearly trainer-oriented build. The Magic Speed 5 looks and feels like a race shoe.

The upper uses the same Engineered Mesh as its predecessor, but this version is noticeably thinner.

The entire shoe now has a racing-spec construction. It feels like the intended use has shifted from “training shoe” toward “race shoe” — a change I welcome.

Comparing the upper of the Magic Speed 4 and 5 side by side, the difference is clear. Even the laces have changed — the Magic Speed 5 uses a serrated lace style more commonly found on race shoes.

The heel construction and overall build have all moved toward lightweight, race-oriented materials.

Sizing: Go Half a Size Up

Sizing deserves attention on this one.

I bought a size 27.5 cm (approximately US 9.5). The verdict: it runs small.

I wore the same size in the Magic Speed 4, but the 5 has noticeably less room at the toe. Whether it’s the thinner upper or last shape, the Magic Speed 5 is definitely smaller. It feels like going back to the Magic Speed 3’s sizing.

Compared to other shoes, it’s close to the ASICS Evoride Speed 3 but feels slightly smaller. It’s still a touch roomier than the MetaSpeed Edge Tokyo or MetaSpeed Edge Paris.

If the Magic Speed 4 fit you perfectly, I’d recommend going up half a size. If you had a little room to spare in the 4, your normal size should be fine.

For reference, here’s my sizing experience across other shoes I’ve run in.

Traction: Still Exceptional

The traction on the Magic Speed 5 is excellent. The outsole uses ASICS GRIP.

ASICS GRIP was first introduced on the original MetaSpeed Sky. It has delivered outstanding traction since day one — reliable even on wet roads.

The Magic Speed 5 uses a new outsole pattern, but the grip performance is fully intact.

Weight: 204g (Size US 9.5)

At a measured 204g in a size 27.5 cm (US 9.5), the Magic Speed 5 is impressively light. The shoe it feels closest to ride-wise is the Adidas Takumi Sen 11, which weighs around 190g — so the Magic Speed 5 is slightly heavier.

Durability

I will update this section as I accumulate more mileage on the Magic Speed 5. The upper is thin by design, but the outsole uses the durable ASICS GRIP rubber.

The midsole also features FF BLAST PLUS on the ground-contact side, which should contribute to longer-lasting cushion performance.

Who Should Buy the ASICS Magic Speed 5?

The Magic Speed 5 is best suited as a race shoe for intermediate runners (targeting sub-3:30 to sub-2:50) and as a training shoe for advanced runners.

Intermediate runners may struggle to fully harness the MetaSpeed Edge Tokyo’s capabilities — the Magic Speed 5 is a better fit for that ability range.

For runners slower than sub-3:30, the shoe may be harder to work with. The Magic Speed 4 rewarded a rolling, ground-contact-style stride; the Magic Speed 5 requires more active push-off to move forward.

From my own testing, 7:14/mile (4:30/km) to 6:26/mile felt like the sweet spot for this shoe. Runners whose race pace falls in that range should find the Magic Speed 5 works well as a race shoe.

My Training Use Cases

Here’s how I plan to use the Magic Speed 5 in my own training:

Of all the shoes in my rotation, this is the most versatile. That said, the carbon plate tends to push your pace faster than intended — so it’s worth being mindful of overuse.
