Step into luxury with Brooks Glycerin 20. Brooks' tradition of making the Glycerin softer and more cushioned continues in version 20. The Glycerin 20 now features nitrogen-infused DNA LOFT v3 cushioning, which is their softest midsole technology. It is optimized to be lightweight, responsive, cushioned and durable while providing a bouncier ride. Brooks redesigned the midsole and outsole by widening the platform for smooth and easy transitions. The upper gives you a secure fit thanks to plush and breathable engineered air-mesh. One reviewer said "the Brooks Glycerin 20 fits true to size. It has a light, flexible upper that wraps comfortably around my foot. The heel collar and tongue feel super soft, and the laces are slightly textured to prevent slippage. A bonus is that the laces are long enough to tie the marathon loop. The materials feel premium and add to the overall plushness of the shoe," in our Brooks Glycerin 20 review. Plus, the toe box has more volume for your toes to spread out. If you want a tighter-fitting knit upper, then look at the Brooks Glycerin Stealth Fit 20. Plush, responsive and comfortable, the Brooks Glycerin 20 lets you forget your feet and focus on your run.
