Saucony Guide 19 vs Brooks Adrenaline GTS 25

Two popular support shoes with different philosophies. The Guide steadies you with a broad, rockered platform and a 6 mm drop for mild support. The Adrenaline uses Brooks' GuideRails and a traditional 10 mm drop for more noticeable support, and it comes in four widths.
