Asics Gel-Cumulus 27 vs Brooks Glycerin 22:
Which to Choose

On paper these two are near-twins — matched cushioning, responsiveness, and stability scores, no plate, neutral support, and virtually identical stack heights (around 38.5mm at the heel on the Cumulus, roughly 39mm on the Glycerin), so cushioning depth is effectively a wash. The first concrete split is drop: the Cumulus runs an 8mm offset while the Glycerin keeps a traditional 10mm, so the Glycerin sits you a little further back on the heel and rewards heel strikers, whereas the Cumulus's lower ramp nudges you toward a smoother midfoot-to-forefoot roll. The second is weight — the Cumulus is the lighter shoe at roughly 261g (men's 9) against about 289g for the Glycerin, a noticeable ~28g gap that makes the Asics feel a touch more nimble when you do pick up the pace, while the Brooks feels more planted and plush but also more of a chore to turn over quickly. Foam character differs too: the Cumulus pairs FF Blast+ ECO with a PureGEL heel unit for calm, forgiving, rounded landings, while the Glycerin's nitrogen-infused DNA Tuned foam gives a slightly livelier, gentler spring and leans on wide, sidewall-supported sidewalls for a composed, steadying base. Both go muted if you push much past roughly 5:00/km, and both are durable everyday workhorses — the Cumulus's AHAR outsole covers the high-wear zones well — so no one is buying either of these for speed.
