Why this Shoe Works

Plush underfoot, mile after mile

Step in and the Glycerin GTS 23's DNA Tuned midsole does the talking — a nitrogen-infused foam with softer cells in the heel for cushioned landings and firmer, springier cells up front for an easy toe-off. It's that premium, sink-in-but-not-mushy feel Glycerin fans keep coming back for. Soft where you land, lively where you leave.

An upper that makes room for your foot

The Glycerin GTS 23's engineered triple-jacquard knit is soft, breathable, and accommodating — it gives wider and higher-volume feet room to settle without pinching or hot spots, while still holding your midfoot securely so your foot doesn't slide around. Your toes stay free to splay, the knit moves with you, and it comes in multiple widths so you can match the shoe to your actual foot shape instead of forcing your foot into the shoe. Roomy where you need it, secure where it counts.

Support that works quietly in the background

Brooks GuideRails sit along the midsole and only kick in when your stride drifts, gently keeping excess movement in check — no hard medial post, no corrective feel. The guidance is light enough that it never fights you; it just keeps things tracking straight when your form starts to loosen. Help you feel only when you need it.

Built For How You Move

Your plush daily trainer

Easy miles are where the Glycerin GTS 23 lives. The soft DNA Tuned foam takes the edge off Phoenix pavement while the GuideRails keep you tracking straight when your form starts to loosen, so daily training feels comfortable and repeatable. Not a fast shoe — a feel-good one. The pair you reach for on autopilot.

Built for long days on hard floors

Twelve-hour shifts and concrete are brutal on feet, and the Glycerin GTS 23 is one of our go-tos for them — plush, cushioned, and gently supportive from the first hour to the last. Nurses, teachers, and folks working retail and service across the West Valley lean on it. Comfort that outlasts the shift.

Easy walking and recovery

On a recovery day or a long walk, the soft landings and smooth roll let your legs settle while the GuideRails keep everything aligned. Neighborhood loops, travel days, errands around Glendale — it stays comfortable from the first block to the last. Easy on the legs.

Who Is the Brooks Glycerin GTS 23 For?

The Brooks (women's) Glycerin GTS 23 is for the runner or walker who wants a soft, premium ride with a little guidance built in.

The GuideRails are gentle enough that a wide range of runners enjoy them — whether you've felt your stride wander late in a run, deal with mild arch or knee discomfort, or just like the reassurance of a shoe that keeps things tracking straight.

The plush DNA Tuned cushioning and accommodating knit upper make it a favorite for easy daily miles, long runs at relaxed paces, and long days on hard floors — and with multiple widths, it fits broad and high-volume feet well.

It's a cushioned trainer first and a support shoe second, so it suits ladies who want comfort that doesn't wobble rather than a firm, corrective feel.

Who Should Skip It

We'd rather point you to the right shoe than sell you the wrong one. Skip the Glycerin GTS 23 if…

You want less guidance underfoot

If you'd rather a shoe without the GuideRails, look at the Brooks Ghost Max 3 or the Hoka Arahi 8 V.

You want even more structure

For a stride that needs more than gentle guidance, the New Balance 860 V15 (the women's Beast) offers a more supportive structured ride.

You want speed or a lighter shoe

At 9.8 oz it's a cushioned trainer, not a fast shoe. For tempo and race days, look at a lighter trainer like the Asics Superblast 3.

You're heading off-road

It's a road shoe. For trails, look at the HOKA Stinson 7 or Altra Olympus 6.

How it Compares

Gray Asics Kayano 33 running shoe with pink sole on a white background

Brooks Glycerin GTS 23 vs. ASICS Gel-Kayano 32

These two land in nearly the same place: premium, cushioned daily trainers with guidance-based support and no traditional medial post, both around an 8 mm drop and similar weight (10.8 vs ~10.5 oz), both carrying the APMA Seal. The difference is feel. The Glycerin GTS 23's DNA Tuned foam is plush and a touch lively, with a roomy, accommodating knit; the Kayano 32 pairs FF Blast+ foam with a PureGEL heel and ASICS's 4D Guidance for a slightly more structured, more locked-in ride.
Choose the Glycerin GTS 23 for the plush DNA Tuned ride and a roomier fit. Choose the Kayano 32 for ASICS's guidance system and a snugger, more secure hold. We carry both.

Blue and purple Hoka Gaviota 6 running shoe with white sole and purple accents on a white background

Brooks Glycerin GTS 23 vs. HOKA Gaviota 6

Both are max-cushion shoes with built-in support, but they feel different underfoot. The Glycerin GTS 23 is softer and plusher (DNA Tuned) with a higher 8 mm drop and gentle GuideRails guidance. The Gaviota 6 is firmer and more planted — denser CMEVA foam, a lower 6 mm drop, and an H-Frame plus a wide base for a more structured, steady feel, in a roomier high-volume fit, and it's a touch lighter (≈10.0 vs 10.8 oz).

Frequently Asked Questions

What's the difference between the Glycerin GTS 23 and the regular Glycerin 23?

Same shoe, one difference: the GTS adds Brooks's GuideRails. They share the same plush DNA Tuned midsole, stack, and drop, but the GTS has guidance built along the midsole that gently keeps excess movement in check. If you want a little reassurance or your stride tends to drift, go GTS; if you want the same cushion with nothing guiding it, the standard Glycerin 23 is the one.

Does the Glycerin GTS 23 have a medial post?

No. Instead of a traditional hard medial post, it uses GuideRails — guidance that sits along the sides of the midsole and only engages when your stride drifts, so it guides rather than corrects. How much support any runner needs comes down to the whole foot and how it loads, not a label — the surest way to know is a quick fit session in Glendale.

Is the Glycerin GTS 23 good for walking and standing all day?

Yes — it's one of our top picks for it. The plush DNA Tuned cushioning takes pressure off your feet, the GuideRails add gentle support for long hours, and it carries the APMA Seal of Acceptance. Nurses, teachers, and anyone on hard floors all day do well in it.

Is the Glycerin GTS 23 good for wide or high-volume feet?

Often, yes — the knit upper is accommodating and it comes in Medium (D), Wide (2E), and Extra-Wide (4E). Keep in mind "wide" is a blanket term, though: the foot is three-dimensional, with instep height, girth, and arch length all in play alongside width. Your foot should sit on the platform without spilling over; if it does, go wider, not longer. Best to have both feet measured in person.

Is the Glycerin GTS 23 true to size?

Close, but it runs a touch short for some runners. Order your normal size and leave about a thumbnail's width past your longest toe — and if you're between sizes or right at the top of your size, try a half-size up. The roomy upper handles a thicker sock or an orthotic well, and a little heel slip on the first few steps is normal.

Is the Glycerin GTS 23 breathable enough for Phoenix?

Its engineered knit upper breathes well and stays comfortable on warm Phoenix mornings, on the treadmill, and through all-day wear. It's a substantial, cushioned shoe rather than a thin summer racer, so for peak-summer speed work a lighter mesh will feel airier — but for everyday miles and long days on your feet, it's a comfortable warm-weather pick.

What changed from the Glycerin GTS 22 to the 23?

Brooks added 2 mm more DNA Tuned foam in the forefoot and lowered the drop from 10 mm to 8 mm, so the ride feels softer up front and more balanced overall. There's also a new engineered triple-jacquard knit upper for a plusher, more breathable fit, and the GuideRails feel a little less intrusive than before.

How does the Glycerin GTS 23 compare to the HOKA Gaviota 6?

Both are max-cushion shoes with built-in support, but they feel different. The Glycerin GTS 23 is softer and plusher (DNA Tuned) with a higher 8 mm drop and gentle GuideRails guidance. The Gaviota 6 is firmer and more planted — denser foam, a lower 6 mm drop, and an H-Frame plus a wide base for a more structured feel, in a roomier high-volume fit. Pick the Glycerin for a softer ride with light guidance; pick the Gaviota for a firmer, more planted feel. We carry both and can compare them on your feet.

How durable is the Glycerin GTS 23 — how many miles?

Plan on roughly 300–500 miles of running, typical for a cushioned daily trainer, and the durable rubber outsole holds up well. Walkers and all-day wearers usually get many months out of a pair. When the cushion goes flat or the support feels less steady, it's time for a new pair.

What's your return policy?

Our "You = Happy" policy gives you 60 days from purchase for a refund, exchange, or store credit. Refunds need the shoes in like-new condition; worn-but-not-worn-out pairs can still earn an exchange or store credit. Receipt or purchase-history lookup required. The Glycerin GTS 23 isn't carbon-plated, so it's fully returnable (clearance and plated shoes are final sale). Online orders can be mailed back or returned in person in Glendale to skip shipping.

Why Our Team Recommends the Brooks Glycerin GTS 23

The Glycerin GTS 23 is one of our easiest recommendations for the runner who loves a soft, cushioned shoe but finds her legs get tired or her stride starts to wander late in a run. We like that the GuideRails guide rather than correct — they're gentle enough that they don't fight a smooth stride, but they're there when fatigue sets in — and that the DNA Tuned foam delivers that plush, premium feel without turning unstable.

It's a favorite for all-day-on-their-feet workers across the West Valley and for runners who want max cushion with a little reassurance. It's not light and it's not fast, and we'll tell you so — but for soft, supported comfort, it's hard to beat.
