Brooks Glycerin GTS 23 Review (2026): GTS 23 150+ Miles Tested — The Plushest Stability Shoe?

The Brooks Glycerin GTS 23 is the most refined stability shoe I’ve tested — combining DNA Tuned nitrogen-infused cushioning with less-intrusive GuideRails in a package that feels like a luxury neutral trainer. In this Brooks Glycerin GTS review, I break down 150+ miles of real-world testing across roads, treadmill, and Atlantic City boardwalk.

I struggled with the stability shoe dilemma for years — trust me, I tried six different stability shoes before finding one that didn’t feel like an orthopedic device. The Glycerin GTS 22 changed my perspective, and the GTS 23 refines everything I loved about that shoe. The new 8mm drop, extra forefoot foam, and triple-jacquard upper make this the most balanced version yet.

I’ve tested the Glycerin GTS 23 for 150+ miles at my 182-lb frame with mild overpronation. This Brooks Glycerin GTS review covers cushioning feel, the refined GuideRails system, how it compares to the GTS 22, and who should buy it. For broader stability options, see my overpronation shoe guide.

Quick Verdict

In my Brooks Glycerin GTS review, I award the Glycerin GTS 23 a 9/10 for overpronators who want maximum cushion without sacrificing comfort or natural stride. Brooks refined the GuideRails geometry and dropped the offset from 10mm to 8mm, creating a smoother heel-to-toe transition that feels less like a stability shoe and more like a premium daily trainer.

Full Specs & Tech

I’ve compiled the full specifications below: the GTS 23 pairs DNA Tuned nitrogen-infused foam with refined GuideRails stability in a new 8mm drop platform. Two key changes from the 22: the drop decreased from 10mm to 8mm, and the forefoot gained 2mm of additional foam for more balanced cushioning.

DNA Tuned foam is Brooks’ nitrogen-infused cushioning technology that uses dual-cell construction — larger cells in the heel for softer landings and smaller cells in the forefoot for firmer, more responsive push-off.

GuideRails is Brooks’ holistic stability system that uses raised sidewalls along the midsole to keep your foot and ankle in their natural motion path — preventing excess inward or outward movement without rigid medial posts or hard plastic inserts.

GTS 23 vs GTS 22 — What Changed

The GTS 23 drops from 10mm to 8mm offset and adds 2mm of forefoot foam for smoother, more balanced transitions. This is the biggest geometry change in the Glycerin GTS lineup in three years, and I noticed the difference immediately on my first run.

Category	GTS 22	GTS 23	Winner
Drop	10mm	8mm	Winner: GTS 23 — More balanced, smoother transitions
Stack (forefoot)	28mm	30mm	Winner: GTS 23 — +2mm forefoot foam for push-off
Weight	10.7 oz (303g)	10.8 oz (306g)	Winner: GTS 22 — 23 is heavier by 3g — negligible
Upper	Double-jacquard knit	Triple-jacquard warp knit	Winner: GTS 23 — Plusher, more breathable, better lockdown
Outsole	Standard rubber	RoadTack rubber	Winner: GTS 23 — Named compound — better grip and durability
GuideRails	Standard geometry	Refined — less intrusive	Winner: GTS 23 — Smoother stability corrections
Cushion Feel	Ultra-plush, absorptive	Plush, slightly more responsive forefoot	Winner: GTS 23 — Better energy return at toe-off
Break-in	15-20 miles needed	10-15 miles needed	Winner: GTS 23 — Faster break-in period

The drop change is the headline upgrade. At 182 lbs with a mild heel strike, the 8mm drop puts me in a slightly more forward-leaning position than the 22’s 10mm. My calves needed about 30 miles to fully adjust, but the payoff is a noticeably smoother transition through midfoot. If you’re coming from the GTS 22, give your body 3-4 runs to adapt to the lower drop.

GuideRails Stability: How It Actually Works

GuideRails guide your natural motion path instead of forcing correction through rigid medial posts or plastic inserts. Here’s why this matters: traditional stability shoes push back against pronation actively. GuideRails use raised sidewalls that act like guardrails on a highway — you don’t notice them until you start drifting.

I tested the Glycerin GTS 23 alongside the Saucony Guide 19 (traditional TPU frame stability) and noticed a clear difference. The Guide 19 pushes back against pronation with a firm medial structure. The GuideRails in the GTS 23 simply prevent excess movement. For mild-to-moderate overpronators like me, the GuideRails approach feels more natural because it works with your gait, not against it.

The GTS 23’s refined GuideRails geometry is subtler than the GTS 22. I noticed less sidewall contact during straight-line running and more engagement on turns and late-mile fatigue — exactly when overpronation worsens. Brooks clearly dialed in the activation threshold.

However, if you have severe overpronation, GuideRails may not provide enough correction. In that case, a more structured shoe like the ASICS Kayano 32 with its 4D GUIDANCE SYSTEM is a better choice. For broader stability options, check my stability shoe guide.

Cushioning & Ride Feel

DNA Tuned midsole delivers the plushest ride in any stability shoe tested across 150+ miles of roads and boardwalk. The nitrogen-infused foam uses dual-cell technology: larger foam cells in the heel for soft landings, smaller cells in the forefoot for a slightly firmer push-off. The extra 2mm of forefoot foam in the GTS 23 makes the transition smoother than the 22.

At easy pace (9:00–9:30/mile), the ride is smooth, protective, and consistent. The 38mm heel stack provides substantial cushioning without feeling unstable. On long runs (12+ miles), the foam maintains its softness — no dead spots or compression at mile 12 that I notice with cheaper foams.

The 8mm drop changes the ride character compared to the GTS 22’s 10mm. I feel slightly less heel-dominant and more balanced through the gait cycle. The forefoot push-off is noticeably improved — still absorptive, but there’s a hint of energy return that the 22 lacked.

Be patient with break-in — it’s normal and I went through the same adjustment. The first 10-15 miles felt firmer than expected. After that, the DNA Tuned foam softened into its optimal state. This is standard for nitrogen-infused foams — they need heat and compression cycles to reach peak performance.

Ride Aspect	Rating	My Experience
Heel Cushion	10/10	DNA Tuned absorbs heel impact beautifully at 182 lbs — plush but not mushy
Midfoot Transition	9/10	8mm drop creates smoother roll-through than the 22’s 10mm
Forefoot Push-off	7/10	+2mm foam helps — still absorptive, but with better energy return
Long Run (60+ min)	9/10	Foam stays consistent — zero degradation at mile 12
Stability Feel	9/10	Refined GuideRails are invisible until you need them

How the Cushioning Actually Feels: My Notes from the Boardwalk

The first time I wore the Glycerin GTS 23 was for a 7-miler on the Atlantic City boardwalk in late February — 38°F, wind off the ocean, boards still slick from overnight rain. By mile 2, the DNA Tuned foam had warmed up and the cushioning felt genuinely soft without the instability I sometimes get from ultra-plush shoes. By mile 5, I forgot the GuideRails were there. That’s the highest compliment I can give a stability shoe.

I’ve since tested it on the Absecon Island road loop (concrete and asphalt mix), a 12-mile long run on boardwalk planks, and two treadmill sessions at the gym. The cushioning consistency is the standout feature — the foam feels the same at mile 1 and mile 12. Cheaper foams bottom out during long efforts. The DNA Tuned doesn’t. At 182 lbs, that consistency matters more than it would for a lighter runner.

Upper, Fit & Comfort

The triple-jacquard warp knit upper is the best-fitting upper Brooks has put on a stability shoe. Breathability rates 9/10 — a clear upgrade from the GTS 22’s double-jacquard, with more visible ventilation zones. It rivals the Nike Pegasus 42’s Flymesh for airflow.

The fit runs true to size. At US 10.5, I have about a thumb’s width in the toe box. The midfoot lockdown is secure without feeling restrictive, and the heel counter grips well without pressure points. Some runners report the toe box feels slightly shallower than the GTS 22 — if you have high-volume feet, try a wide option.

One improvement I notice: the gusseted tongue stays centered during runs. On the GTS 22, my tongue would occasionally slide laterally after mile 5. That issue is gone on the 23 — the triple-jacquard construction holds everything in place.

• Available widths: D (standard), 2E (wide), 4E (extra-wide)
• True-to-size fit — order your normal running shoe size
• Padded tongue with gusseted construction — zero lateral sliding
• Heel counter provides secure lockdown without rigidity
• Triple-jacquard warp knit adapts to foot shape over 10-15 miles

Outsole & Durability

RoadTack rubber outsole projects 400-500 miles of life with minimal wear after 150+ miles of mixed-surface testing. I run primarily on Atlantic City boardwalk planks, asphalt, and concrete. At 150 miles, the outsole shows light wear on the lateral heel but zero concerning thinning. I project this shoe to last 400-500 miles — a stellar durability highlight in my Brooks Glycerin GTS review.

The RoadTack compound is a clear upgrade from the GTS 22’s unnamed rubber. Grip on dry pavement is excellent. On wet sidewalk, traction is adequate but not exceptional — I’d rate it 7/10 on wet surfaces. If you primarily run in rain, a trail shoe is still a better choice.

GTS vs Glycerin 23 (Neutral): Which Do You Need?

The only difference is the GuideRails stability system — foam, outsole, and drop are identical. If you don’t overpronate, the GTS adds unnecessary structure. Don’t worry if you’re unsure — I was confused about this too. If you do overpronate, even mildly, the GuideRails provide valuable protection without compromising ride quality.

Feature	Glycerin GTS 23 (Stability)	Glycerin 23 (Neutral)
GuideRails	✅ Yes — refined holistic stability	❌ No — neutral ride
Weight	10.8 oz (slightly heavier)	10.6 oz
Ride Feel	Guided, controlled at extremes	Free, unrestricted
Best For	Mild-to-moderate overpronators	Neutral runners
Cushioning	DNA Tuned — identical	DNA Tuned — identical
Drop	8mm — identical	8mm — identical

If you’re unsure whether you overpronate, visit a running store for a free gait analysis. Or flip your old running shoes over — heavy wear on the inner heel edge signals overpronation. See my shoe selection guide for more.

Who Should Buy the Brooks Glycerin GTS 23?

The Glycerin GTS 23 is built for overpronators wanting luxury cushioning without the rigid feel of traditional stability shoes. After 150+ miles, here’s my recommendation for each runner type:

Runner Type	Recommendation	Why
Mild-moderate overpronator	✅ Perfect fit	Refined GuideRails provide gentle, effective support
Heavy runner (180+ lbs)	✅ Excellent	DNA Tuned absorbs impact at high bodyweights without bottoming out
Easy/recovery runner	✅ Ideal	Maximum cushion for low-intensity miles
Runner with knee pain	✅ Highly recommended	GuideRails + DNA Tuned reduces joint stress
Shin splints sufferer	✅ Top choice	Shock absorption at this cushion level is therapeutic
Runner with plantar fasciitis	✅ Worth trying	Plush heel cushion takes pressure off the fascia
Speed/tempo runner	❌ Not ideal	10.8 oz is too heavy for fast-paced work
Severe overpronator	⚠️ May not be enough	GuideRails is gentle — severe cases need firmer stability
Neutral runner	❌ Wrong shoe	Get the Glycerin 23 (neutral) instead — same cushion, no stability

Competitor Comparison

The GTS 23 prioritizes comfort over control, unlike the Kayano’s aggressive stability or the Guide’s lightweight approach. Here’s how the four top stability shoes compare after I’ve tested each one:

Best Shoe Rotation with the Glycerin GTS 23

The GTS 23 works best as your comfort shoe in a 2-shoe rotation with a lighter speed-day trainer. I’ve been running 30–40 miles per week with this rotation for the past 8 weeks:

Day Type	Shoe	Why
Easy/recovery runs	Brooks Glycerin GTS 23	Maximum cushion — easy runs don’t need speed
Tempo/threshold	Brooks Ghost 18	Lighter at 10.2 oz and more responsive for faster efforts
Long easy runs	Brooks Glycerin GTS 23	Consistent cushion — foam doesn’t degrade over 60+ minutes
Intervals/speed	Saucony Endorphin Speed 5	PEBA foam for max energy return on fast repeats

For a deeper look at how the Ghost 18 and Glycerin GTS compare, read my Ghost vs Glycerin GTS comparison. Alternatively, if you want a lighter HOKA daily trainer, see my HOKA Clifton 10 review. The short version: the Ghost is my weekday workhorse, the Glycerin GTS is my weekend long-run protector.

Pros & Cons Summary

Here’s my honest pros and cons after 150+ miles of daily training in the Glycerin GTS 23.

✅ What I Love	❌ What Could Be Better
DNA Tuned nitrogen foam — plushest stability cushion tested	10.8 oz — heavier than neutral and some stability alternatives
8mm drop creates smoother transitions than GTS 22’s 10mm	Not for speed — too cushioned for intervals or tempo work
Triple-jacquard upper — best breathability in a Brooks stability shoe	10-15 mile break-in period before foam reaches optimal softness
D, 2E, and 4E widths — covers most foot shapes	Toe box may feel shallow for high-volume feet
RoadTack outsole — projected 400-500 mile lifespan	Wet traction is adequate but not outstanding
Excellent for knee pain, shin splints, plantar fasciitis	GuideRails may not control severe overpronation

Final Verdict

The Glycerin GTS 23 is the best stability shoe for runners who refuse to sacrifice comfort for support in 2026. The 8mm drop, extra forefoot foam, and refined GuideRails make this the most balanced, natural-feeling Glycerin GTS ever built.

If you overpronate and want a shoe that feels like a premium neutral trainer with invisible stability, this is your shoe. The DNA Tuned foam delivers cushioning that rivals the ASICS Nimbus 28 and HOKA Bondi 9 — check out my full HOKA Bondi 9 review for a max-cushion comparison — and the GuideRails system provides support without rigid correction. For max cushion options across all categories, check my best cushioned running shoes guide.

It’s not perfect — the weight is noticeable, the break-in period is real, and speed work requires a rotation partner. But for its intended purpose — protective, cushioned, daily stability training — the Glycerin GTS 23 is the best in the business. If your current shoes are nearing replacement, this is a worthy upgrade.

FAQ

These are the 10 most common questions about the Brooks Glycerin GTS 23, answered from 150+ miles of testing.

Is the Brooks Glycerin GTS 23 a stability shoe?

Yes. The Glycerin GTS 23 features Brooks’ GuideRails holistic stability system with refined geometry. Unlike traditional medial posts, GuideRails uses raised sidewalls to prevent excess foot movement. It’s designed for mild-to-moderate overpronators who want stability without a rigid, controlling feel.

What is the difference between the Glycerin 23 and Glycerin GTS 23?

The only difference is the GuideRails stability system. The Glycerin 23 (neutral) has no stability features. The Glycerin GTS 23 adds GuideRails for overpronation support. Everything else — DNA Tuned foam, triple-jacquard upper, RoadTack outsole — is nearly identical.

What changed from the Glycerin GTS 22 to the GTS 23?

Three major changes: the drop decreased from 10mm to 8mm for smoother transitions, the forefoot gained 2mm of additional DNA Tuned foam, and the upper upgraded from double-jacquard to triple-jacquard warp knit for better breathability and fit. The outsole also switched to the named RoadTack rubber compound.

Is the Glycerin GTS 23 good for flat feet?

The Glycerin GTS 23 works well for mild flat feet with its GuideRails support. However, runners with severe flat feet and significant overpronation may need more aggressive stability. See my flat feet shoe guide for targeted recommendations.

How does the Glycerin GTS 23 compare to the ASICS Kayano 32?

The Glycerin GTS 23 prioritizes plush comfort with passive GuideRails stability. The Kayano 32 uses an active 4D GUIDANCE SYSTEM for more aggressive pronation control. Choose the Glycerin for maximum comfort; choose the Kayano if you need firmer stability correction.

Does the Glycerin GTS 23 run true to size?

Yes. In my experience at US 10.5, the fit is true to size with about a thumb’s width in the toe box. Some runners report the toe box feels slightly shallower than the GTS 22. The shoe is available in D, 2E, and 4E widths for different foot shapes.

How long does the Glycerin GTS 23 last?

Based on my testing, the Glycerin GTS 23 should last 400-500 miles. At 150+ miles, my pair shows minimal outsole wear and no midsole compression. The RoadTack rubber is more durable than the GTS 22’s unnamed compound. See my shoe replacement guide for signs to watch.

Is the Glycerin GTS 23 good for knee pain?

Yes. The combination of DNA Tuned nitrogen-infused cushioning and GuideRails stability makes the Glycerin GTS 23 excellent for runners with knee pain. The cushioning absorbs impact while GuideRails prevent the excess movement that stresses knee joints. See my knee pain shoe guide for more options.

Can I use the Glycerin GTS 23 for walking?

Absolutely. The plush cushioning and gentle stability make the Glycerin GTS 23 an excellent walking shoe. The 8mm drop and DNA Tuned foam provide all-day comfort. Many users buy it specifically for daily walking and extended standing.

Is the Glycerin GTS 23 good for beginners?

Yes — the Glycerin GTS 23 is an excellent choice for beginner overpronators. The GuideRails system is gentle and non-intrusive, so new runners won’t feel restricted. The plush cushioning is forgiving during the adaptation period when your body is adjusting to running forces. See my beginner shoe guide for more options.
