Can it get any better than the Adrenaline 13? Apparently yes it can! The new Brooks Adrenaline 14 is smoother than ever before. Brooks has extended the Caterpillar Crash Pad and added ground contact throughout the length of the outsole creating an even smoother and softer ride. The new lacing design evens out pressure points and the 3D Fit Print creates an even lighter and more flexible no-stitch fit. The only down side to the Adrenaline 14 is deciding which cool color you will chose!
