Description: The fan-favorite Adrenaline returns lighter and softer, with smoother transitions than ever on the Brooks Men’s Adrenaline Gts 24 Running Shoes. Lighter cushioning helps this performance runner weigh in at a feathery-light 10 ounces while improving cushioned support so you can go the extra mile. Plus, GuideRails technology reduces excess shin and heel rotation to keep your natural motion path to take it easy on your knees when you’re pounding the pavement.
