Experience a run that finally lets you lead the way. You will find that the Brooks Glycerin Flex D Men’s Shoes is designed specifically for those moments when you want signature cloud-like comfort without feeling like the shoe is making all the decisions for your feet. By combining high-performance technology with a more natural feel, Brooks has created a ride that acts as a true extension of your body.

At the heart of your experience is the DNA TUNED midsole foam. This nitrogen-infused innovation features a dual-cell structure: larger cells in your heel ensure your landings are incredibly soft and airy, while smaller cells in your forefoot provide a lively, responsive push-off. To give you total freedom, the FlexZone technology incorporates an asymmetrical midfoot flex groove and a podular forefoot design, allowing the shoe to bend and twist naturally with your foot’s organic motion. It is all about giving you the liberty to move on your own terms, whether you are heading out for a long weekend road session or hitting the gym.

Key Features

  • Lightweight: Weighing only 249g (size 9 USM), this reduces fatigue and ensures effortless turnover during your daily training or gym sessions.
  • 6mm Drop: This encourages a more natural foot strike and uninhibited movement compared to traditional high-drop running shoes.
  • Engineered Flat Knit Upper: Highly breathable construction that offers a flexible, second-skin fit while using 62.8% recycled materials.
  • FlexZone Midfoot Flex Groove:  Provides flexibility and support through the midfoot to encourage more natural transitions in your stride.
  • DNA TUNED Nitrogen-Infused Cushioning: You get a perfectly balanced ride with plush landings and powerful toe-offs through this innovative dual-cell foam structure.
  • Men’s Standard Width (D) Fit: This provides a secure yet accommodating midfoot lockdown that works with the flexible upper to adapt to your foot’s natural shape.
  • Podular Forefoot Design: This delivers targeted lateral flexibility to support your natural gait cycle while maintaining a stable and protective platform.

Yes, it is designed for versatility. While it is a high-performance road running shoe, it is also recommended for everyday runs, long miles, and workouts at the gym.

Yes. The Glycerin Flex features a removable insole, allowing you to replace it with your own custom orthotics. The flexible upper and secure heel lockdown help maintain a stable fit even with additional inserts.

While both use DNA TUNED foam, the Glycerin Flex is tuned for flexibility and agility. It uses a single-layer foam process to reduce weight and bulk, whereas the Glycerin Max uses a higher stack height for maximum impact protection and a rockered ride.
