Soft and smooth. These Brooks Men's Adrenaline GTS 20 Road Running Shoes offer balanced, soft cushioning. Full-length, responsive BioMoGo DNA cushioning provides a touch of spring underfoot while DNA LOFT in the heel ensures super soft landings. With GuideRails® Holistic Support System, Brooks shifted their focus beyond the feet to the most injury-prone part of a runner's body: the knees. GuideRails support keeps you moving comfortably by keeping excess movement in check. Streamlined, engineered mesh uppers with 3D Fit Print offers the structure and proven fit the Adrenaline is known for—without excess bulk.
