The Platinum edition of the Go-To Shoe is here! (Not physically, but you know, 20 years) Brooks takes what you loved about the Adrenaline 19 and makes it smoother and more streamlined with a better-integrated GuideRails support system and a tweaked asymmetrical 3D Fit Print upper and saddle to secure a breathable engineered mesh to the foot. Still with a touch of spring and a touch of soft to keep the miles ticking away seamlessly, the Adrenaline GTS 20 is locked, loaded and ready to go!
