Designed to offer a perfect balance of support and softness, the Adrenaline GTS 22 offers a smooth, soft ride ready for all your miles. All of Brooks' running shoes prioritize comfort, but the GuideRails® technology adds support by keeping excess movement in check. So you stay in your natural stride, even when you get tired. Midsole now consists of 100% DNA LOFT cushioning for a soft, smooth ride. No wonder these supportive running shoes have been known for over twenty years as a runner favorite.
