Asics GT-2000 15 Review: The Test We Should Have Run First

Four days ago, RunMorph published a full review of the Asics GT-2000 13, calling it the world's best-selling Asics stability shoe. The problem: the GT-2000 15 had already launched in the US two days earlier, on August 1, 2026. In other words, that article covered a model already two generations behind. We're setting the record straight here, no detours: this is the real review of the GT-2000 15, the direct replacement for the 13 and the 14 in the Asics lineup, and we're as blunt about its strengths as about what still doesn't work.

Asics GT-2000 15: the real new stability benchmark in the Asics lineup

Asics had already done the hard part with the GT-2000 13: ditching the punishing stiffness of old-school stability shoes for more progressive support. The GT-2000 15 keeps the same philosophy and takes it further. Two concrete additions: 2 mm more stack height and FF BLAST MAX foam replacing FF BLAST PLUS, with a softer feel and more bounce. You notice it from the first strides: there's more material underfoot, and the shoe still feels planted and reassuring.

On the outside, the upper switches to an engineered woven construction, meant to improve breathability and wrap the foot more naturally than the previous generation's Jacquard mesh. On paper, everything points the same way: more comfort, same level of support. In practice, it's not that simple, and we'll come back to it below.

GT-2000 15 specs

The price stays the same as the GT-2000 13 despite the upgrades, which is good news. Note that the shoe isn't widely available in French stores yet as we publish this review: the August 1 US launch comes a few weeks before general availability in France, a typical lag for Asics.

FF BLAST MAX, 3D Guidance System, PureGEL: what really changes underfoot

FF BLAST MAX is the foam doing all the work here. Softer than the GT-2000 13's FF BLAST PLUS, it gives more generous cushioning at ground contact and a clearer rebound at toe-off, without ever turning unstable, which is what you might fear on a stability shoe. It's the first change runners who already know the GT-2000 series pick up on.

The 3D Guidance System hasn't moved an inch. Same principle as before: a wider base at the heel and midfoot, a redesigned external heel counter, and an upper that channels the foot toward a neutral position without physically locking it in. This is stability that guides rather than corrects, and it remains the GT-2000's signature. The PureGEL in the heel rounds out the package: this gel formula, 65% softer than standard Asics Gel, absorbs heel impact on long runs and late in a run, when fatigue sets in and your stride breaks down.

RunMorph's tip: if you've already read our GT-2000 13 review, the question isn't whether the 15 is better (it is, on paper and on the road), but whether the change in firmness suits you. If you liked the 13 for its firmer, more planted feel, the 15 will surprise you: in a good way for most runners, in a bad way if you're very attached to the original feel.

On the road: from easy runs to long runs

At easy-run pace, between 5:30 and 6:30/km, the GT-2000 15 feels good right away. The FF BLAST MAX absorbs well, the PureGEL's softness in the heel comes through from the very first footstrikes, and the 3D Guidance System's support stays discreet as long as your stride is clean. On a 25 to 30 km long run, the gap with the GT-2000 13 holds up: your feet stay fresher for longer, and late-run fatigue is easier on your joints.

Once the pace climbs toward 4:45-5:00/km, the shoe shows the usual limits of this type of product: you feel the 252 g, the geometry isn't built for quick surges, and stability takes over from responsiveness. That's neither a surprise nor a real criticism; a stability daily trainer was never meant to be a racing shoe. What bothers us more is that tight toe box we mentioned above: it makes itself felt from kilometer 15, with a slight squeeze on the forefoot that wasn't there on the GT-2000 13.

GT-2000 15 vs. Brooks Adrenaline GTS 24 vs. Saucony Guide 19: stability shoe comparison

The road stability category has no shortage of serious contenders. Here's how the GT-2000 15 stacks up against two direct rivals RunMorph has already reviewed.

Against the Brooks Adrenaline GTS 24, the GT-2000 15 is lighter and has a more modern foam, but it costs around twenty euros more for a comfort gain that mainly pays off if you run high mileage. Against the Saucony Guide 19, both play the same card: support without stiffness. The Guide 19 has a lower drop and a more wrapped fit at the rear, while the GT-2000 15 is lighter but held back by its narrow toe box. On weight and responsiveness alone, the GT-2000 15 comes out on top of the three.

Our take: which runners is it for?

Runners who overpronate and want comfort above all

This is the GT-2000 15's natural target. The FF BLAST MAX plus PureGEL combo makes this shoe much more pleasant than the 13 over long distances, without giving up any support.

Marathoners in a training block

With generous cushioning and a lower weight, the GT-2000 15 holds up through an entire marathon build, long run after long run, as long as your feet aren't too wide.

Runners with wide feet or a sensitive forefoot

This is the profile that should steer clear, or at least try it on in a store before buying. The tight toe box can turn a great stability shoe into a recurring source of discomfort as the kilometers add up.

The RunMorph Coach verdict

The Asics GT-2000 15 does what a good update should: it improves what could be improved (comfort, weight, rebound) without touching what already worked (the support of the 3D Guidance System). The result is one of the best stability daily trainers on the market right now, and it clearly replaces the GT-2000 13 as the benchmark in the Asics lineup.

But we won't kid ourselves about the toe box: it's a real flaw, not a marginal comfort detail, and you should know about it before buying rather than discover it at kilometer 20 of a long run. At €150, the GT-2000 15 remains a very good investment for runners who overpronate and have standard or narrow feet. If your feet are wide, try before you commit.

Final score: 8.5/10.
