Brooks Glycerin 22 vs Salomon Aero Glide 3:
Which to Choose

On the numbers, both are max-cushion neutral shoes with high cushioning (5/6), above-average foam-driven responsiveness (4/6), moderate stability (4/6), and no plate — so rebound in each comes purely from the midsole. The clearest, most decisive difference is weight: the Aero Glide 3 lands around 249g (8.8oz) in a men's 9 versus roughly 289g (10.2oz) for the Glycerin 22, a gap of about 40g that you feel directly in how each shoe carries at speed. That weight advantage is why the Salomon holds a faster gear more willingly (its brisk zone sits around 4:40–5:00 min/km) while the softer, slightly heavier Glycerin is happiest at relaxed steady-state efforts and starts to dull once you push past about 5:00 min/km. The Aero Glide also runs a touch taller — roughly a 42mm heel stack against the Glycerin's ~39mm — giving it a fractionally more built-up, protective platform underfoot despite being the lighter shoe. Ride character diverges accordingly: the Glycerin's nitrogen-infused DNA Tuned foam is plush and pillowy with a gentle spring and a wide, sidewall-supported base that keeps transitions composed and planted, whereas the Aero Glide's Energy Foam TPU/EVA blend feels lively and forgiving but flattens into a pleasant roll rather than a snappy toe-off when you reach for turnover. Both use a traditional-to-moderate heel-to-toe offset (the Glycerin at a confirmed 10mm), so neither will feel unfamiliar to a heel or midfoot striker. On fit, the Glycerin leans accommodating and comfort-first, while the Salomon's upper feels a bit more performance-oriented and secure over the midfoot — worth trying on if foot-hold or forefoot room is a priority for you.
