What’s New with the Glycerin Flex?
Everything! This brand-new offering from Brooks introduces a truly unique shoe to the market unlike anything we have seen before. The Glycerin flex takes flexibility to a new level, allowing your foot to move freely and effortlessly. It boasts a moderate 36mm of DNA Tuned, the nitrogen-infused midsole that we have come to know and love from Brooks. Dual-cell technology offers larger cells in the heel for plush landings and smaller cells in the forefoot for responsive toe-offs. However, the true star of the show is the midfoot flex groove, allowing full flexibility, more ground-feel, and the ability to move with any foot. The strategically placed cutouts provide a unique and flexible underfoot feel. The flexibility continues with the all-new knit upper, offering enough stretch to accommodate narrow and wide feet alike. The padded heel collar provides a secure fit around the ankle to reduce slippage. The stretchy pull-tab and tongue allow for easy step-in and unrestricted comfort for daily miles.
