Glycerin 23 GTS

The Brooks Glycerin GTS 23 is the stability-enhanced version of Brooks' premium daily trainer, built for runners who want generous cushioning without giving up support. It takes everything that makes the Glycerin 23 exceptional and adds Brooks' trusted GuideRails system for runners who need a little extra guidance through their stride.

The nitrogen-infused DNA Tuned midsole features an additional 2mm of foam in the forefoot compared to previous versions, delivering soft, cushioned landings at the heel and an energetic, responsive feel through toe-off. It is the kind of midsole that makes miles feel effortless — especially on longer runs when leg fatigue starts to set in.

The GuideRails support system works by limiting excess movement at the knees and ankles rather than rigidly correcting your foot strike. The result is a more natural feeling ride that gently guides your stride back into alignment only when needed, staying completely out of the way when your form is on point. A broad, stable platform reinforces this controlled feel underfoot, giving you confidence on every footfall.

The triple jacquard knit upper rounds out the package with a luxurious, secure fit that accommodates the foot comfortably across both daily training distances and longer efforts.

For runners who want premium cushioning with subtle, reliable support that never feels intrusive, the Glycerin GTS 23 hits the mark.
