Brooks Glycerin Flex - Plush Comfort Meets Natural Motion

Stay connected to every stride with the Glycerin Flex. Combining generous cushioning with midfoot flexibility, this trainer adapts to your natural movement pattern whilst delivering the plush comfort Glycerin fans expect. From easy morning miles to gym sessions and everything in between, the Flex gives your foot freedom to move as it wants.

Nitrogen-infused DNA Tuned foam combines large cells in the heel for airy landings and small cells in the forefoot for powerful toe-offs. The 36mm heel and 30mm forefoot stack height delivers substantial cushioning without the rigid feel of max-stack trainers. This dual-density construction absorbs impact with every footstrike whilst maintaining responsive energy return when you pick up the pace.

Strategic cutouts and asymmetrical flex grooves change how the shoe behaves through the stride. Rather than feeling like one solid slab rolling forward, the platform flexes and "opens up" as you move—it works with the biomechanics of your feet, rather than controlling them. The FlexZone™ technology allows the heel and forefoot to move semi-independently, creating smoother transitions and reducing the internal cost of rigid shoes fighting against your natural gait.
