#6. Brooks Adrenaline GTS 15 ($100.00 @ Amazon.com)
Adrenaline junkies will fall heel-over-toe in love with the 14th edition of these Brooks perennial crowd pleasers. Brooks replaced the mid-foot shank with foam allowing for more ground contact and in turn a smoother heel-to-toe transition. Over-pronators will instantly notice the increased support thanks to the caterpillar crash pad. While the 3D Fit Printing overlays and brand new eye-row embrace your feet no matter what you and your adrenals drag them through.
