Ultimately, the choice between these two rides depends on your personal running style and preferences.
Support and Stability Differences
As you shift your focus from cushioning to support, you'll find the Brooks Glycerin 21 features a more substantial and supportive ride, thanks to its segmented crash pad and Omega Flex Grooves that work in tandem to provide a smooth heel-to-toe shift.
