The Brooks Glycerin Stealthfit GTS 20 combines support and softness with a sleek fit to give you a winning stability shoe. Brooks’ 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. It is optimized to be lightweight, responsive, cushioned and durable while providing a bouncier ride. The Glycerin Stealthfit GTS 20 uses Brooks’ signature GuideRail® 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 check—perfect for those who overpronate or have flexible arches and want a little more support. Brooks redesigned the midsole and outsole by widening the platform for smooth and easy transitions. The new StealthFit construction provides for a closer fit that adapts to the movements of your foot. It is seamless and breathable with stretch and compression to move with you as you run. If you want a shoe with more volume, look at the Brooks Glycerin GTS 20, which has an engineered air-mesh upper. Brooks Glycerin Stealthfit GTS 20 delivers plush comfort, excellent stability and a close-to-foot fit.
