Men's Brooks Adrenaline GTS 20 - Black/White The Go-To-Shoe is turning 20 and isn't slowing down. New, integrated GuideRails support is smoother than ever while just-right cushioning softens every step. DETAILS: Responsive BioMoGo DNA cushioning stacked above a soft DNA LOFT Crash Pad work together to provide a touch of spring underfoot while cushioning each footfall. A shifted focus beyond the feet to the most injury-prone part of a runner's body: the knees. GuideRails keep you moving comfortably by keeping excess movement in check. A new streamlined, engineered mesh upper with 3D Fit Print offers the structure and proven fit the Adrenaline is known for — without excess bulk.
