Women's Brooks® Glycerin Max :: Whoever said running isn't easy, has never stepped foot into the new Women's Brooks Glycerin Max. Every step feels like you're walking on clouds, thanks to the all-new Nitrogen-infused DNA Tuned midsole that acts like a pillow to brace you for a softer impact. The GlideRoll Rocker works in harmony to ensure smooth heel-to-toe transitions. With larger cells in the heel for plush landings and smaller cells in the forefoot for responsive toe-offs, every jog, sprint, or training in your Glycerin Max becomes an effortless and exhilarating journey you won't ever want to end.
