The fan-favorite Adrenaline returns lighter, softer, and with smoother transitions than ever on the Men's Brooks 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.
