Glycerin vs. Glycerin Max: What’s best for you?

The Max series and its vital role in cushioning

The technology behind the new Max versions of various Brooks running shoes emerges from our in-depth understanding of what many runners truly crave — maximized cushioning for optimal comfort and protection.

Our Max running shoes, including the fast and springy Hyperion Max 2, signify Brooks’ commitment to this understanding. They’re not just shoes; they’re a promise that helps ensure every footfall is softer, every mile is more comfortable, and every run is distraction-free.

In the new Glycerin Max, we have gone above and beyond to optimize airy softness and electrifying responsiveness by using two types of nitrogen-infused cushioning, seamlessly tuned into one midsole.

The Glycerin series and the Glycerin Max: A side-by-side comparison

Shoes in the Glycerin series and the Glycerin Max are closely related yet subtly different. Let’s see how they stack up against one another in three key aspects.

1. Supreme comfort: The cornerstone of the Glycerin series’ design is the nitrogen-infused DNA LOFT v3 cushioning. The latest version of our DNA LOFT technology provides even more softness while ensuring the shoe remains lightweight, responsive, and durable.
   
   The Glycerin Max features DNA Tuned, the next generation of nitrogen-infused foaming created with a tuned dual-cell technique to provide plush landings and responsive toe-offs. With more foam underfoot, the Glycerin Max has a higher stack height than the Glycerin 21.
2. Protection: The Glycerin 21 is also available in custom configurations for the right fit. Glycerin GTS 21 uses GuideRails™ support to help keep you moving comfortably while supporting your natural stride.
   
   Both the Glycerin 21 and Glycerin GTS 21 are available in StealthFit, now featuring an updated flat knit  upper that moulds to your foot for a blend of stretch and compression. This new configuration is designed to move with you, while the new materials feel super soft against your foot.
   
   The Glycerin Max offers plenty of DNA Tuned to help protect your body from impact, helping keep your legs feeling fresh after every run.
3. Seamless transitions: The Glycerin series’ midsole and outsole work in harmony to offer a wide platform for smooth, easy transitions, maximizing efficiency and comfort.
   
   The Glycerin Max features our GlideRoll Rocker to help promote heel-to-toe transition.

The luxurious comfort of the Glycerin lives on

The Glycerin is firmly established as a high-performing daily running shoe for both long runs and easy runs. Each shoe in the Glycerin series carries that legacy forward with new innovations, thoughtful touches, and even more comfort.

Building upon each iteration, the Glycerin features a design grounded in feedback from real runners.

• Glycerin 21 offers supreme softness in a premium package: DNA Loft v3 cushioning underfoot for a cushier ride. Nitrogen-infused DNA LOFT v3 provides ultimate softness with the right blend of responsiveness and light weight for a comfortable run, mile after mile.

• Glycerin StealthFit 21 has the supreme softness of the Glycerin 21 with a versatile design: The adaptable StealthFit’s updated flat knit  upper moulds to your foot for a blend of stretch and compression that moves with you. Plus, the new materials feel super soft against your foot.
• Glycerin StealthFit GTS 21 includes everything featured with the Glycerin StealthFit above, plus extra support: Our GuideRails™  support system assists your body in embracing its natural motion path while helping to limit excess motion.

Every feature in the Glycerin series has evolved through years of research and runner insights to bring you supremely soft underfoot technology and silky-smooth transitions. Each shoe in the series is designed to let you focus less on your feet and more on your run.

Max cushion in the Glycerin Max

The Glycerin Max is built differently through an innovative process that integrates two types of nitrogen-infused cushioning into one seamlessly tuned midsole. Here is how the Glycerin Max is redefining running:

• Expertly tuned cushion: Introducing DNA Tuned, the next generation of nitrogen-infused foaming created with a tuned dual-cell technique. The heel features large cells for plush landings, while the forefoot features small cells for responsive toe-offs. This innovative foam reduces added layers and processes for a seamlessly tuned experience.
• Effortless transitions: Our expertly crafted GlideRoll Rocker features dramatically sculpted bevel and toe spring geometries to help promote heel-to-toe transition.
• Stacked to the Max: A boundary-pushing amount of DNA Tuned helps protect your body from impact and will leave your legs feeling fresh day after day.

The Glycerin Max is for anyone who wants maximum soft cushioning to provide ultimate ease and comfort in every step.

Keep it classic or MAX your comfort

Every runner has individual preferences and needs, and choosing from the Glycerin series truly depends on you.

If tradition is preferred, the Glycerin 21 and the other shoes in this series have been honed through multiple iterations and remain a versatile choice for a variety of running experiences.

If you prioritize maximum soft cushioning over everything else, the all-new Glycerin Max could be your go-to. With its increased heel and forefoot cushioning and features like the GlideRoll Rocker, the Glycerin Max may be the shoe for you.

Whatever your choice, let’s run there.
