The Brooks Glycerin Flex is a neutral daily training shoe that combines a significant amount of cushioning with a flexible sole. The goal of this is to provide a natural feeling foot strike with the ground. The Glycerin Flex uses the same DNA Tuned midsole as the Glycerin counterparts. At 9.1 ounces, the shoe offers some versatility with uptempo paces. The 38mm stack height also gives it sufficient cushioning for longer efforts. The flexible nature of this shoe makes for a very neutral offering, but does fill a void for those wanting something that is both flexible and highly cushioned.
