I’ve had a long history running in the Brooks Glycerin. My first foray with the shoe was pre-COVID, with the Glycerin 17 back in 2019. That feels like 10 years ago, not five. With the nitrogen-injected DNA LOFT v3 foam, the shoe has improved leaps and bounds from its previous iterations. But how does it stack up against the Glycerin 20 and Ghost Max?
