Leave your distractions behind you and take off in the Men’s Brooks Adrenaline GTS 21. This is Brook's legendary support shoe made even softer, with a secure fit that feels like a glove-but for your feet. The engineered upper hugs the foot for a tailored fit and breathability while the DNA Loft cushioning goes beyond the heel, all the way to the forefoot, for a buttery smooth stride. All of Brooks' running shoes prioritise comfort, but the GuideRails technology in the Men's Adrenaline GTS 21 adds additional support too by keeping excess movement in check. So you stay in your natural stride, even when you get tired.
