DNA Tuned supercritical foam
The complete Brooks Glycerin lineage
The Glycerin is Brooks's plush premium neutral trainer, the step up from the Ghost: same easy-miles mission, more foam, roughly $25 more. The modern era splits into three foam chapters. The classic DNA Loft 18 and 19 (2020-21) were soft, smooth and, in hindsight, a little dead. The nitrogen-infused DNA Loft v3 rebuilt the platform in the 20 (2022), the version one tester called the best Glycerin Brooks has ever made and the one loyalists still hoard. The DNA Tuned supercritical foam arrived with the 22 (2025) and split those same loyalists. Along the way the family sprawled. In 2021 Brooks killed the Transcend and folded it in here as the Glycerin GTS, a GuideRails support variant of each numbered shoe rather than a line of its own. A knit StealthFit variant ran from the 20 through the 22, retired when the 23's standard upper went knit. The 45 mm Glycerin Max (2024, where DNA Tuned debuted) and the flexible Glycerin Flex (2026) are separate shoes outside this succession.

Thinking about leaving the Glycerin?
We ranked the shoes that ride closest to it (a plush, smooth-rolling premium cruiser that stays composed rather than bouncy) and called out the honest differences.

- What is the newest Brooks Glycerin?
- The Brooks Glycerin 23, released in 2026. List price at launch was $175.
- Which Brooks Glycerin versions are hard to find now?
- Glycerin 18, Glycerin 19, Glycerin 20. They are discontinued at retail, so Amazon carries whatever stock remains and sizes disappear one by one.
- Which Brooks Glycerin should I buy?
- New to the line: buy the Glycerin 23. If you loved the way this line rode before the Glycerin 22 changed its character in 2025, the Glycerin 21 was the last version of the old ride, and remaining stock is the only way to get it.
