The Brooks Glycerin GTS 23 is a plush, structured-support road-running shoe Brooks positions for everyday and long runs. Its defining feature is GuideRails, which Brooks says helps keep excess motion in check; that is a description of the design, not evidence that the shoe prevents injuries or is right for every runner. The published specifications and Brooks’ comparison with the Glycerin 23 and Adrenaline GTS 25 can help you decide whether its approach matches what you want.
What the Glycerin GTS 23 is designed for
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. The GTS designation distinguishes it from the standard Glycerin 23, which Brooks describes as offering balanced support.
Those labels explain Brooks’ intended positioning; they are not a prescription based on your gait, a medical recommendation, or a guarantee of how the shoe will feel. The available product information does not establish independent test results or an individual fit assessment.

It also describes the upper as a new engineered knit intended to provide softness, breathability, and all-around comfort. Those material and comfort descriptions come from Brooks; they are not independently verified wear-test findings.

The comparison points to the practical distinction Brooks emphasizes: choose between the two Glycerin models based on whether you want Brooks’ structured-support or balanced-support positioning, and consider the Adrenaline if its listed walking use and lower observed US price are relevant to you. These descriptions do not establish that one model is medically necessary or objectively better for a particular runner. The weights in this comparison are from Brooks’ US women’s listing and should not be generalized to other sizes or regional listings.

What this review can and cannot establish
This is an evidence-based review of Brooks’ published product information, not a hands-on wear review. No independent lab test or wear test was established for this assessment, so it cannot substantiate claims about real-world durability, independently measured cushioning, or injury outcomes. Brooks’ descriptions are useful for understanding the shoe’s intended design and positioning, but they do not replace trying the shoe or assessing your own fit and comfort.
