The Grivet Take
The Glycerin GTS 23 is Brooks's premium stability cushion shoe, now on the new DNA Tuned foam with the drop pulled down from 10mm to 8mm. Forefoot stack is up 2mm, weight is down by almost an ounce, and the dual-density foam reads softer at the heel and snappier at the toe-off. GuideRails are still here, and engagement is fit-dependent: some runners find them more guided than the v22, others find them gentler. Best for daily easy miles, long runs, and long days on your feet, especially if you want premium cushion plus guided stability and don't mind a heavier shoe. Skip it for tempo or race days; the foam is plush, not propulsive.

Support
Support TypeSupport Type describes how much built-in guidance the shoe has. Neutral shoes do not add support structure. Stability shoes use geometry, rails, firmer foam, or frame designs to create a more guided feel. Motion control shoes are the maximum-support category and are rare in modern running.

How it fits
Fits true to size for most runners. New triple-jacquard upper is plush and breathable, with enough natural stretch to accommodate medium and high-volume forefeet. Toe box runs standard width with adequate vertical room; runners with low-volume narrow feet may want to size down a half size or pick the standard width over wide. Heel hold is secure thanks to a generous padded collar, but the collar is firm; some runners report Achilles or back-of-heel rubbing, especially in the first 20-30 miles. Available in Standard (D) and Wide (2E) for men's. Try them on if you're between sizes; some runners report the v23 sizing slightly short.
How it feels
Cushion is high without going to max territory. Reads soft when walking and firms up under running pace. The new DNA Tuned foam is dual-density: bigger cells in the heel for softer landings, smaller cells in the forefoot for a snappier toe-off. Forefoot rocker is moderate with adequate flex through deep diagonal grooves. Energy return is moderate but not bouncy; this shoe protects more than it propels. GuideRails engage along the sidewall through the gait cycle rather than just under the arch, producing a guided rather than corrected feel. Allow 20-30 miles to break in.

Tech, translated
DNA Tuned is Brooks's new nitrogen-infused midsole foam. The cell structure is dual-density: bigger cells under the heel for softer landings, smaller cells in the forefoot for firmer push-off. The result is a shoe that feels plush on the heel strike and snappier through toe-off.
GuideRails are firmer reinforcements built into the sidewalls of the midsole. They engage when the foot moves further than the shoe's geometry was designed for, gently keeping motion in check without forcing a fixed path.
Triple-jacquard upper is the new flagship element. The mesh has natural stretch and flexes with the foot. Fit and breathability come up consistently as standout in long-run testing.
What changed from the previous version
Drop dropped from 10mm to 8mm by lifting the forefoot 2mm; heel stack stays at 38mm. Brooks swapped DNA LOFT v3 for DNA Tuned, a nitrogen-infused dual-density foam. Weight came down from 11.7 oz to 10.8 oz in men's 9, and the new triple-jacquard upper is plusher and more breathable than the v22 mesh. GuideRails return, with reactions split on whether they engage more prominently or more gently than v22. The heel collar is firm; runners with sensitive Achilles areas may want to test before committing.
Frequently asked
Does the Brooks Glycerin GTS 23 run true to size?
Yes, the Glycerin GTS 23 fits true to size for most runners, though some report it sizing slightly short. Brooks offers Standard (D) and Wide (2E) widths for men's. The new triple-jacquard upper has natural stretch and accommodates medium and high-volume forefeet comfortably; runners with low-volume narrow feet may prefer to size down a half size or pick the standard over the wide.
What changed from the Brooks Glycerin GTS 22?
Brooks pulled the drop from 10mm to 8mm by lifting the forefoot 2mm; heel stack stays at 38mm. The midsole moved from DNA LOFT v3 to DNA Tuned, a dual-density nitrogen-infused foam with softer cells in the heel and firmer cells in the forefoot. Weight came down from 11.7 oz to 10.8 oz in men's 9, and the new triple-jacquard upper is plusher and more breathable. GuideRails return, and runners loyal to the v22's firmer corrective feel may want to compare back-to-back before upgrading.
How does the Brooks Glycerin GTS 23 compare to the Brooks Glycerin 23?
The Glycerin GTS 23 is the same shoe as the neutral Glycerin 23 with GuideRails added along the sidewall. Both share the new DNA Tuned dual-density foam, the 38mm/30mm stack, and the triple-jacquard upper. Choose the GTS for guided stability built in. Choose the neutral Glycerin 23 for a lighter shoe without the sidewall rails.
Is the Brooks Glycerin GTS 23 firm or soft underfoot?
Cushioned but firm-leaning underfoot, especially before break-in. The new DNA Tuned foam is dual-density: heel cells are softer for cushioned landings, forefoot cells are firmer for a snappier toe-off. Walking pace makes the shoe feel plush; running pace firms it up. Allow 20-30 miles for the foam to settle.
Is the Brooks Glycerin GTS 23 good for walking?
Yes, the Glycerin GTS 23 is well-suited to walking and long days on your feet. The 38mm stack and dual-density DNA Tuned foam read soft at slower loading rates, and the GuideRails along the sidewall provide gentle guidance for tired feet. It's heavier than a dedicated walking shoe at 10.8 oz, but the cushion and stability make it work for all-day-on-feet use as well as easy running miles.
Is the Brooks Glycerin GTS 23 good for wide feet?
Yes. The Glycerin GTS 23 is available in Standard (D) and Wide (2E) widths for men's, which covers most foot shapes. The new triple-jacquard upper has natural stretch and accommodates high-volume feet well. Runners with extra-wide forefeet should pick the 2E; standard-width feet should be comfortable in the D.
Is the Brooks Glycerin GTS 23 good for treadmill running?
Yes. The full-rubber outsole holds up to belt wear, and the cushioned ride is forgiving for repeated foot strikes on the same surface. At 10.8 oz the shoe is on the heavier side for treadmill running, so longer treadmill efforts may feel more sluggish than they would in a lighter daily trainer. For easy and steady-state treadmill miles, it's a comfortable pick.
