Women's Glycerin Flex

The Glycerin Flex takes the plush DNA foam of the Glycerin line and cuts a wide groove across the full midsole, so the shoe folds nearly in half. It moves with your foot instead of rolling it forward, which runners who like a natural stride tend to love. It’s lighter and firmer than the Glycerin 23, with a 6 mm drop and a one-piece stretch knit upper that fits like a sock. It works as a daily trainer, a walking shoe, and a treadmill or gym-cardio shoe. Three colors at a clearance price, limited sizes.
