The Glycerin Max 2 is Brooks' biggest shoe: the tallest stack of dual-cell DNA TUNED foam the brand makes, rolled through the stride by a GlideRoll rocker. Soft cells in the heel take the landing, firmer cells in the forefoot return the push, and the whole thing weighs a substantial 320 g.
It suits you if long easy miles are the point of your running and you want the maximum protection Brooks sells — the kind of shoe you finish a two-and-a-half-hour Sunday in and feel less used up than usual.
It is not a versatile shoe. At this weight and stack it has one gear, and asking it to do a workout is asking a sofa to sprint. If you want tall AND quick, that is the Hyperion Max's brief, not this one's.
