Its defining feature is Brooks’ GuideRails system, which the company says is designed to support the body’s natural motion path and help keep excess movement in check. Those are manufacturer descriptions, not evidence that the shoe prevents injuries or is right for every runner.
This review explains the shoe using Brooks’ published product information; it is not based on an independent wear test. The practical decision is whether its stated support approach and specifications suit what you are looking for, and how it differs on paper from the Glycerin 23 and Adrenaline GTS 25.

What kind of running shoe is the Glycerin GTS 23?
Brooks categorizes the Glycerin GTS 23 as a road-running shoe for everyday runs and long runs. The company describes its cushioning as plush and its support as structured. “GTS” distinguishes this model’s GuideRails support system from the standard Glycerin 23, which Brooks describes as offering balanced support.
That positioning can help narrow a shortlist, but it is not a prescription. Brooks’ product descriptions do not establish that a particular runner needs structured support, or that the shoe will change their injury risk or running mechanics.

How does GuideRails support work?
Brooks says GuideRails is designed to support the body’s natural motion path and help keep excess movement in check. The company’s product page describes it as a system that “helps keep excess movement in check.” This is Brooks’ explanation of the design intent; it should not be read as proof of injury prevention or as a guarantee that the shoe will control an individual runner’s movement.
If support is your main reason for considering the shoe, treat GuideRails as a feature to assess alongside fit and comfort—not as a medical solution. The available product information does not report independent testing of its effects.

What changed in the cushioning and upper?
DNA TUNED cushioning
Brooks says the GTS 23 has 2 mm more nitrogen-infused DNA TUNED cushioning in the forefoot. That is a manufacturer-reported design change; the product information cited here does not provide independent measurements of softness, energy return, or performance.
Engineered-knit upper
Brooks describes the upper as a new engineered knit intended to provide softness, breathability, and all-around comfort. Those are stated design aims, not independently verified wear-test findings. On the US women’s page, Brooks also lists 60.3% recycled materials in the upper; that percentage is the manufacturer’s product metric.

How does it compare with the Glycerin 23 and Adrenaline GTS 25?
Brooks’ US women’s product comparison distinguishes the three shoes by support positioning, intended use, drop, listed weight, and the prices shown on that page. The figures below are specific to that comparison, and prices can change.
| Model | Brooks’ support description | Listed use | Drop | Listed weight | US price shown |
|---|---|---|---|---|---|
| Glycerin GTS 23 | Structured support | Road running; everyday runs and long runs | 8 mm | 9.8 oz | $180 |

| Adrenaline GTS 25 | Structured support | Structured support; road running, walking, and reliable comfort | 10 mm | 9.5 oz | $155 |
Brooks showed these US prices on the product page captured for this review; they are not guaranteed current prices or prices for other regions. The company’s comparison supports a distinction in positioning, not a universal ranking: the Glycerin GTS 23 and Adrenaline GTS 25 are both described as structured-support options, while the standard Glycerin 23 is described as balanced support.

Who should consider the Glycerin GTS 23?
It is worth considering if you are shopping for a road shoe that Brooks positions as plush, structured, and suitable for both everyday and long runs. Its published specification includes an 8 mm drop, while the listed weight depends on the particular regional and gendered product page.
It may be useful to compare the standard Glycerin 23 if you prefer Brooks’ balanced-support positioning, or the Adrenaline GTS 25 if you want a structured-support model that Brooks also lists for walking. The product descriptions alone cannot determine which shoe will fit your foot or feel best while running; try-on comfort and sizing remain individual.
What this review can—and cannot—establish
This assessment is based on Brooks’ product descriptions and listed specifications, not an independent lab test or hands-on wear test. It therefore cannot report real-world durability, how the cushioning feels over time, or whether the shoe improves comfort or reduces injury risk for a specific runner. Brooks’ US page displayed customer ratings and reviews, but retailer-hosted feedback is not a controlled test and can change.
