Not all cushioning cells are built the same size, and the Glycerin Max makes that a feature. Larger nitrogen-infused cells sit under the heel for soft landings, while smaller, denser cells up front add responsiveness for takeoff. GlideRoll Rocker geometry ties the two together for a smooth transition, a 6mm drop reduces strain on the plantar fascia, and a breathable engineered air mesh upper keeps things comfortable at 10.5 oz.
Why does the Glycerin Max use different cell sizes in the heel and forefoot? The Brooks Glycerin Max's dual nitrogen-infused cushioning is tuned by zone — bigger cells cushion the landing, smaller ones add spring at toe-off.
