Brooks Glycerin Flex

The Brooks Glycerin Flex is an all-new training shoe designed to give a flexible, natural ride in a cushioned package. Priced at $170, it competes in the daily trainer segment with the Salomon Aero Glide 3 ($160) and Nike Vomero Plus ($180). The Glycerin Flex is a new entrant into the shoe market for Brooks and it introduces the use of Flex Grooves, a segmented and disjointed outsole that is marketed to allow more foot articulation. They are using a version of the DNA Tuned foam that seems similar to that used in the OG Glycerin Max. The step-in feel is incredible with a dialed, soft upper with good lockdown, a comfortable heel, an accommodating, yet appropriately snug fit with soft, stretchy laces. While we didn’t notice the flex groove technology out on the run, which is a good thing, we did find the ride to be extremely enjoyable and smooth. While not a low-stack speed trainer, it is a very solid workhorse daily trainer that encourages good mechanics and offers good protection, bounce, and agility. If you are looking for a fun and peppy daily trainer with great mid-foot bounce, a perfectly tuned foam, and a geometry that encourages you to get up on your forefoot, the Glycerin Flex would be a great option.
