The ASICS GEL-KAYANO 32 and the Brooks Adrenaline GTS 23 are both longstanding support trainers aimed at overpronators, but they offer very different ride experiences. The Adrenaline uses Brooks' GuideRails system for support, paired with a high-drop, traditional geometry that feels more structured through the heel but less adaptable overall. Its midsole is noticeably firmer and absorbs less impact, giving it a harsher feel. The ASICS, in contrast, delivers a softer and more protective ride with a smoother heel-to-toe transition thanks to its lower drop and added forefoot stack. It still offers plenty of support thanks to its 4D Guidance sidewalls.
The Mizuno Wave Horizon 9 and Brooks Glycerin GTS 23 are both premium stability trainers that cost the same, but they suit slightly different runners. The Horizon 9 is more stable and a touch better cushioned, while the Glycerin GTS 23 is a hair lighter and provides support in a less intrusive way. Neither is particularly lively, so the decision mostly comes down to support needs: get the Horizon 9 if you need the most secure ride possible; get the Glycerin GTS 23 if you want a more of a stability shoe with gentler support.
