These grooves make the Flex, you guessed it, extremely flexible (you can fold the shoe in half by hand). The midsole is made from DNA Tuned, a supercritical foam infused with large gas bubbles in the heel and smaller ones in the forefoot, so you get plush cushioning on landing and springy response at toe-off. Overall, the ride is sublime: The Flex delivers excellent shock absorption without the hefty bulk of other max-cushion shoes.For Brooks, the Glycerin Flex represents an entirely new approach to shoe design, moving beyond the maximalism that has dominated running shoes over the past few years. Instead of surrounding your foot with a thick block of foam, the Glycerin Flex’s highly flexible sole lets your foot follow its natural motion while still providing soft cushioning.
