You already love the support. Now it comes with even more softness in the women's Adrenaline GTS 21, a road-running shoe that feels like it was made for just your stride.
GuideRails® holistic support system
We’ve shifted our 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.
