The Danner Mountain 600 Leaf 4. 5in GTX Hiking Boot is our loyal trail companion. As we venture into the backcountry time and time again, the GORE-TEX-backed leather uppers keep our feet dry through puddles and protected against rocks, while the stabilizing yet high-energy midsole foam delays fatigue. Rain or shine, the outsole's sticky Vibram rubber secures our steps, and when hundreds of miles have chewed the lugs down, this pair can be resoled for a whole new round of adventures.
