How does the Glycerin 22 differ from the Glycerin 21?

The 22 swaps in the new DNA Tuned midsole, which is nitrogen-infused and tuned for a softer heel and firmer forefoot. The upper is an engineered double jacquard knit for a more accommodating fit. The 10mm drop carries over.

Is the Glycerin 22 good for long runs?

Yes. Brooks positions it for road running and long runs, and the plush DNA Tuned cushioning is meant to keep legs fresh over high mileage. It is a neutral, balanced-support shoe.

How does it compare with the Hoka Bondi?

The Bondi is softer and heavier with a thicker stack. The Glycerin 22 is lighter and feels more like a conventional trainer, with a firmer forefoot for toe-off.

Does it fit true to size?

Brooks lists it as true to size, and the knit upper is described as accommodating for a range of foot shapes. Runners between sizes often stay with their usual Brooks size.

What is the drop and stack height?

It has a 10mm drop, with a 38mm heel and 28mm forefoot stack. That is a moderate drop that suits most heel and midfoot strikers.

Is it a stability shoe?

No. It is a neutral shoe with balanced support, not a posted stability model. Runners who need motion control should look at Brooks' Adrenaline GTS instead.
