Glycerin Flex

Meet the Glycerin Flex, Brooks' most flexible cushioned trainer yet. Innovative flex grooves and a podular design work together to move with your foot, so you get a natural, unrestricted stride without giving up that signature Glycerin cushioning.
Powered by nitrogen-infused DNA TUNED foam, it delivers soft landings and responsive toe-offs in one seamless midsole. A cushioned daily trainer that runs on your terms.
