Softness and support combine to give you the ultimate run in the Brooks Glycerin GTS 20. Brooksrsquo tradition of making the Glycerin GTS softer and more cushioned continues in version 20. The Glycerin GTS 20 now features nitrogen-infused DNA LOFT v3 cushioning, which is their softest midsole technology and takes you on a bouncy ride. It is optimized to be lightweight, responsive, cushioned and durable. The Glycerin GTS 20 uses Brooksrsquo signature GuideRailreg technology along the heel and midfoot to give the shoe stability and support. This innovative technology supports your body in its natural motion path while keeping excess movement in checkmdashperfect for those who overpronate or have flexible arches and want a little more support. Brooks redesigned the midsole and outsole by widening the platform to make for smooth and easy transitions. The upper gives you a secure fit thanks to plush and breathable engineered air-mesh. 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 GTS StealthFit 20. Plush, responsive and supportive, the Glycerin GTS 20 will keep your mind off your feet and on your workout.
