The Brooks Glycerin Max takes cushioning to new heights. Delivering a soft yet responsive feel for miles of comfort, this neutral trainer’s brand-new nitrogen-infused DNA Tuned midsole and GlideRoll Rocker geometry give you smooth transitions and an effortless ride. In our Brooks Glycerin Max review, wear tester Mandy said, “The Glycerin Max offers the perfect combination of cushion and propulsion with a nice rocker shape to keep me running.” Whether you're out for a casual run or logging serious miles, the Glycerin Max will keep your legs feeling fresh from start to finish. Details: Upper: The engineered triple jacquard material wraps your foot securely, while breathable materials keep your feet cool on the go. Soft padding on the tongue and heel collar add instant step-in comfort and a luxurious feel to this daily trainer. Midsole: Brooks’ brand-new DNA Tuned midsole uses dual-cell, nitrogen-infused foam. Large cells in the heel and midfoot create soft landings, while small cells towards the forefoot give you responsive toe-offs. Then, the GlideRoll Rocker geometry gently nudges you forward for a smooth stride.
