Women's Brooks® Glycerin 22 :: You lace up your updated Women's Brooks Glycerin 22 running shoes, step outside, and feel the rush of the open road beneath you. They're your ticket to that PR you've been working so hard for. With DNA LOFT v3 cushioning, its new dual-size cell technology cradles your foot, larger cells in the heel give you plush landings, while smaller cells in the forefoot deliver a burst of energy with every toe-off. The upgraded double jacquard warp knit upper in the Glycerin 22 molds to your foot, offering a second-skin feel, while smooth, stable transitions keep you moving with confidence.
