Our Verdict

Brooks Adrenaline GTS 24

Brooks Glycerin 22

The Brooks Adrenaline GTS 24 and Brooks Glycerin 22 are both daily trainers, but they’re built around different priorities. The Adrenaline GTS 24 is the dedicated stability shoe, with a broad support-focused platform, firmer forefoot, and guide-rail-style support that gives it a more controlled feel underfoot. The Glycerin 22 is the more cushioned, comfort-first option, with better heel and forefoot protection, a roomier fit, and slightly more rebound overall. Neither shoe feels especially snappy, but the Glycerin 22 is the better pick for a softer, more comfortable daily trainer for running or walking. The Adrenaline GTS 24 is the one to reach for if you need structured support to help with overpronation.
