Get a close-to-foot fit and extreme softness every step of the way in the Brooks Glycerin Stealthfit 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. A 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 20which has an engineered air-mesh upper.
