The Brooks Glycerin GTS 23 takes the premium, plush cushioning of the standard Glycerin and adds a layer of intelligent, non-intrusive support. It is a highly supportive, balanced shoe that proves you do not have to sacrifice speed, versatility, or comfort to get the stability your body needs.
Support: The GuideRail Advantage
The defining feature of this shoe is Brooks' GuideRails support system. Instead of forcing your foot into a rigid, corrected posture from the very first step, the GuideRails act like the bumpers on a bowling alley.
The support acts as a helpful tool specifically for when your gait tires. During the later miles of a run, when fatigue sets in and your form starts to get sloppy, the shoe catches that subtle inward roll and keeps your stride in a nice, neutral position throughout. It is support exactly when you need it, and completely unobtrusive when you don't.
Performance: From Easy Miles to Race Day
Usually, heavily cushioned stability shoes are relegated to slow, easy recovery runs. However, the Glycerin GTS 23 is excellent for all types of runs. It transitions beautifully from easy runs to tempo efforts.
To put its versatility into perspective: I used this exact shoe for my debut triathlon, and it also carried me to a Half-Marathon Personal Best (PB). It provides the protective cushioning needed to keep your legs fresh over 13.1 miles, but it doesn't hold you back when you want to put your foot on the gas.
The Verdict
The Brooks Glycerin GTS 23 is an exceptional all-rounder. It delivers elite-level comfort, intelligent support that adapts to your fatigue, and enough responsiveness to smash a PB on race day. If you need stability but still want a dynamic, plush ride, come down to the store and try them out for yourself!
