A firmer, bouncier update that feels lighter than its weight thanks to DNA Tuned break-in and delivers higher stability via a medial post; battling the Kayano 32 for Matt's stability shoe of the year and a clear improvement over the previous, too-soft version.
Best for: Runners who want a bouncier heel, a higher heel drop, a more flexible forefoot, and who like the feeling of a medial post with pressure under the arch — higher-stability needs than a stable-neutral trainer.
+2 earlier reviews from Doctors of Running
A firmer, more secure, and noticeably more stable iteration that returns the Glycerin GTS to its premium stability roots; better for runners wanting real stability but may over-correct pronation for some.
Best for: Runners who found v21 too soft or wanted more stability/control from a premium stability trainer
The softer, more traditional-feeling Glycerin GTS that the reviewer prefers over v23, especially on sale, for its cushier midsole and clearer medial support.
Best for: Runners who want a softer stability ride with a clear medial post feel and narrower fit.
