Brooks Adrenaline GTS 26 review: a comfier upper on the same trusted ride

Some shoes earn their update status by changing everything. The Adrenaline earns its by changing only a few things, and the Adrenaline GTS 26 is exactly that kind of update; the same trusted stability platform with the comfort refinements aimed where they were actually needed.

Iit keeps the Adrenaline GTS 25's core untouched: nitrogen-infused DNA LOFT v3, the GuideRails support system, a 10mm drop on a 36mm/26mm stack.

What's new lives up top: a soft flat-knit tongue, a refreshed flat-knit collar, and a heel loop for easier entry.

Having run in it alongside my memories of the Adrenaline GTS 25, my take is simple; very similar to the previous version, with a more comfortable upper, and a heel-biased cushion profile that continues to make this a particularly great shoe for heel strikers.

I have been testing the Brooks Adrenaline GTS 26 through daily miles, steady efforts, and time on feet, and here's my full review, including who should upgrade and who can wait.

Sizing and fit

True to size, with the fairly accommodating volume the Adrenaline line is known for, and the strong width lineup means most runners won't need to size around the fit.

The upper is where this version earns its keep: the new flat-knit tongue is thinner, softer, and hugs the top of the foot instead of sitting on it like the Adrenaline GTS 25's padded version, the refreshed collar wraps the ankle without rubbing, and heel lock remains excellent.

The flat-knit heel loop is a small touch that makes a real difference for easy on and off.

Performance review

A 26th version carries a specific burden; don't break what a quarter century of runners rely on, and fix what they've been quietly tolerating. Here's how the Adrenaline GTS 26 handles both.

The same trusted ride, and that's the point

Underfoot, this is very similar to the Adrenaline GTS 25.

It's soft, balanced, predictable, and stable, with the reengineered DNA LOFT v3 adding a slightly smoother transition and a touch more life at toe-off rather than changing the shoe's character.

That continuity is the feature, not the flaw. The Adrenaline remains the stability shoe that doesn't feel like one, and the dependable daily trainer you reach for when the plan says steady miles, long runs, recovery days, or hours of walking; yes, it's a great walking shoe too.

GuideRails: stability you only notice when you need it

Brooks' support system remains the quiet benchmark for non-intrusive stability: raised sidewalls from heel to midfoot that act as bumpers, engaging only when your foot strays from its natural path.

There's no medial post fighting your stride, and for most of a run you'd swear you were in a neutral shoe.

The GuideRails system announces itself late in a run, when form starts to break down and the guidance keeps everything tracking straight.

That's exactly when a stability shoe should speak up, and it's why the Adrenaline has held this lane for so long.

The flat-knit upper is the real upgrade

If the Adrenaline GTS 25's update was about the midsole, this one is about everything touching your foot.

The old padded tongue was the Adrenaline GTS 25's one comfort niggle, adding bulk and warmth over the top of the foot.

The new flat-knit version is thinner and more flexible, curving with the foot instead of stacking padding on it, and together with the refreshed collar it makes the Adrenaline GTS 26 meaningfully more comfortable over long sessions.

It's the kind of change you stop noticing precisely because nothing bothers you anymore.

Built for heel strikers, honestly

The cushion distribution hasn't changed, and it's worth being direct about it: the heel is the plush, protective zone, and the forefoot still runs a touch firmer and less cushioned by comparison.

For heel strikers, that geometry is a gift; confident, cushioned landings exactly where the impact happens, transitioning cleanly through the 10mm drop without ever feeling unstable up front.

This shoe is particularly great for heel strikers, and I'd put that near the top of the reasons to buy it. Midfoot and forefoot strikers will notice the relative firmness up front more readily, and may be happier on a more evenly cushioned platform.

Know its pace, its weight, and its value

My pair weighs 10.7oz (303g) in a US 9, half an ounce up on my Adrenaline GTS 25 pair, and this remains a heavier shoe than many neutral daily trainers. It isn't built for speed work, and it doesn't pretend to be.

At $155 it holds the Adrenaline GTS 25's launch price, and the upgrade case depends on where you're coming from: if your Adrenaline GTS 25 still has life, there's no rush, especially with that model dipping toward $125 on clearance.

If you're coming from a Adrenaline GTS 24 or older, you get two generations of added softness plus the comfier upper, and the jump is worth it.

Durability should hold the line's strong reputation, with the outsole historically showing minimal wear deep into a shoe's life.

My verdict

The Adrenaline GTS 26 is another dependable evolution of Brooks' flagship stability trainer: the same reliable, guided, protective ride as the Adrenaline GTS 25, now with the upper comfort the last version was missing.

It shines for overpronators and heel strikers logging daily miles, long runs, recovery days, and plenty of walking, and the quiet GuideRails support still makes it the stability shoe for runners who don't want to feel like they're wearing one.

Buy it knowing its lane: it's not light, it's not fast, and the forefoot stays firmer than the heel. Neutral runners are better served by the Brooks Ghost 18, and if you want maximum cushion with your stability, my On Cloudrunner 3 Max review covers that brief.
