Brooks Glycerin 23
Brooks Glycerin 23
Plush, stable daily trainer with soft DNA Tuned cushioning and roomy fit, best for easy miles.
The Brooks Glycerin 23 is a plush, no-nonsense daily trainer that feels like a luxury mattress for your feet—made for runners and long-shift warriors chasing relentless comfort and recovery miles. Experts and users agree its nitrogen-infused DNA TUNED midsole, 38/30 mm stack, and 8 mm drop deliver cushy landings and smoother roll, though reviewers note the ~10.6 oz (M9) weight and muted energy return blunt tempo ambitions. The triple jacquard upper earns praise for a roomy toe box but draws heat/fit comments, and certifications like APMA/PDAC A5500 add medical cred—value hinges on premium comfort over speed.

Believe in the Run praises the Brooks Glycerin 23 as a reliably comfortable, premium-feeling daily trainer with a well-executed DNA Tuned midsole that delivers plush heel cushioning and a stable, smooth ride. The reviewer is fond of its durability, crossover comfort for long on-feet days, and tasteful styling, but their enthusiasm is tempered by clear criticisms: the shoe has gained weight, feels too close to the new—and lighter—Glycerin Flex, and its overly warm, overly padded triple-jacquard upper (especially the tongue) reduces breathability and summer run comfort. Price is another sticking point at $175 for a non-plated, non-superfoam trainer. Overall the tone is measuredly positive—appreciative of ride and comfort—yet cautiously critical about value, redundancy in the lineup, and suitability for true performance running.
RTINGS praises the Brooks Glycerin 23 as a plush, comfort-focused daily trainer that continues the series’ legacy of excellent heel cushioning and stable platform, but the review’s tone is measured and cautiously critical rather than effusive. The testers highlight meaningful improvements—higher stack, reduced drop, and a more structured yet flexible triple-jacquard upper—while calling out clear drawbacks: heavy construction, minimal energy return, and forefoot compression that leads to bottoming out on long runs, making it subpar for marathons or racing. Unique insights include Brooks’ nitrogen-injected DNA Tuned foam strategy (larger heel cells, denser forefoot), thorough size/variant testing (including Wide/Extra Wide), and direct comparisons to rivals (ASICS Gel-Nimbus 28, Saucony Triumph 23), which frame the Glycerin 23 as a dependable, comfort-first choice best suited to heel strikers and everyday miles rather than speed or long-distance competition.

Eric - Running Content/ReviewsEric “Rad Dad Bod” McIntyre highlights the Glycerin 23’s key change — a reduced drop (10→8mm) and softer DNA-tuned foam in the forefoot — and sounds genuinely excited about how that will improve daily cushioning and fit for lower-drop runners. He praises the sticky new outsole and familiar, breathable upper while noting this is an evolution rather than a radical overhaul. Overall consensus: He recommends the Glycerin 23 as a more appealing, cushioned daily trainer for runners who prefer a 4–8mm drop, expressing curiosity and optimism rather than full-throated raving; he invites feedback from traditional higher-drop fans, so his recommendation is enthusiastic but measured.
natalie rog ✮⋆nmarierog (natalie rog ✮⋆) highlights feeling "like I'm walking on clouds" with the Brooks Glycerin 23—immediate, plush cushioning impressed them on a first run, especially as a heavier-footed runner replacing worn HOKAs. They note quick break-in and strong comfort on their usual multi-run weeks in rainy PNW conditions. Overall, natalie warmly recommends the Glycerin 23 for runners seeking soft, highly cushioned shoes straight out of the box, framing it as a successful upgrade with no major complaints mentioned in this clip.

Store Reviews
CUSTOMER REVIEWS FROM 1 STORE
Amazon reviewers overwhelmingly praise the Brooks Glycerin 23 for plush cushioning and day-long comfort. Runners and people who stand for hours report reduced foot and back pain and describe the midsole as soft but supportive on longer runs. Several users highlight a roomy vertical and horizontal toe box compared with prior models, and one runner praised Brooks for removing a previous upper design that irritated bunions. Many buyers also note solid arch and heel lockdown that keep feet secure without feeling heavy. Fit receives mixed feedback: multiple reviewers say the shoe runs small or a bit narrow, prompting recommendations to order a half size up or choose wide widths, while others call the fit true to size. A few users request slightly more forefoot support around the big toe. Overall, Amazon customers value the Glycerin 23 for its cushioned ride, improved upper comfort, and strong support for walking, long shifts, and running.

Brooks’ reputation for comfort-first trainers shows up loud and clear in the Glycerin 23: a premium neutral daily shoe tuned for long miles, recovery runs, and on‑your‑feet days. At its heart sits nitrogen‑infused DNA TUNED foam, reworked with +2 mm forefoot stack to soften toe‑offs, paired with a 38/30 mm stack and 8 mm drop that smooths heel‑to‑toe flow. The plush triple jacquard warp‑knit upper gives a roomier toe box and secure lockdown, while a wide platform and sculpted midsole deliver steady, confidence‑inspiring transitions. Expect a durable full‑length rubber outsole for road miles, though weight and muted snap temper speed ambitions — roughly 10.6 oz (M9). If you’re a neutral runner, heavier foot, or recovery‑day devotee who values cushioning over tempo, this shoe is built for you; read on to see which trade‑offs matter most to your miles.
DNA TUNED cushioning
Brooks’ nitrogen‑infused DNA TUNED midsole is the headline act: large heel cells for plush landings and smaller forefoot cells for cleaner toe‑offs, with an extra 2 mm forefoot that genuinely softens the ride. In testing it soaks up long‑run shock and eases joint strain, though experts note modest energy return compared with livelier foams; user feedback backs the “pillow” feel while flagging occasional forefoot compression on extended efforts. Overall, it’s a comfort‑first foam engineered for recovery and daily miles, not race day snap.
Platform stability and transitions
A wide platform and strategic midsole sculpting produce impressively smooth, stable transitions—think forgiving roll without wobble—making the shoe feel confidence‑inspiring as fatigue sets in. The combination of zonal DNA cells and a broader base helps runners maintain form on longer efforts, with both testers and users noting fewer stumble moments and reliable midfoot support. It’s stability by geometry rather than rigid guidance, excellent for daily miles but less suited to those wanting aggressive guidance for overpronation.
Stack height and drop
At 38/30 mm with an 8 mm drop, the Glycerin 23 moves toward a lower, more balanced platform that smooths transitions without forcing a rocker gait. That extra forefoot stack plus the reduced drop helps mid/forefoot strikers feel less abrupt toe‑off, while heel strikers enjoy plush landings; reviewers confirm a noticeably softer forefoot versus prior models. It’s a deliberate tweak that favors long, easy days over aggressive tempo work, delivering cushioned protection and steadier heel‑to‑toe rhythm.
Weight and ride responsiveness
The Glycerin 23 leans into plushness at the cost of sprightliness: roughly 10.6 oz (M9) yields a cushy, protective ride but a perceptible heft that blunts tempo efforts and quick surges. Experts and vloggers both remark on added mass versus lighter Glycerin variants, and while the DNA TUNED foam cushions brilliantly, it offers muted energy return, so the shoe shines for recovery and long runs rather than fast intervals. Expect comfort‑centric performance, not flashy responsiveness.
Upper construction and fit
The triple jacquard warp‑knit upper is plush, breathable and forgiving, creating a roomier toe box that many users praise for bunion relief and all‑day comfort. Lockdown is secure thanks to padded collar and lace chain, though the short, non‑gusseted tongue draws recurring complaints for shifting or rubbing on long outings. Fit skews true‑to‑size for many but wide feet often prefer the wide option for ideal comfort; overall the upper trades off seasonal breathability for luxe plushness.
Conclusion
Think of this as a comfort-first verdict: the nitrogen‑charged DNA TUNED cushioning soaks up miles, the raised stack height and 8mm drop smooths roll, and the plush upper construction and fit welcomes wider feet. A broad platform keeps transitions confidence‑inspiring, while the full‑coverage outsole traction and durability handle road miles with quiet competence. Trade-offs are real: the shoe’s weight dulls quick efforts and the ride’s muted snap limits tempo ambitions. If you live for easy runs, recovery days, or long shifts on your feet, this is a calming daily companion; if you chase race‑day zip, look elsewhere. Overall: a thoughtfully tuned, durable trainer that prioritizes protection and comfort over fireworks—precisely what its supporters and critics have been saying.
