The Millet Men's Switch GTX Hiking Boot boasts long distance comfort in an ultralight package for backpackers. Gore Tex provides waterproof breathable protection, and the synthetic upper stays strong while a carbon blend offers foot wrapping comfort. The cushy OrthoLite insole has antimicrobial properties to reduce odor after long days in warm weather. Underfoot, Millet added a full layer of EVA to ensure a cushy hike to the campsite. There's also a dual density EVA layer at the heel to reduce shock, and the arch stabilizer ensures spot on walking through mountainous terrain. Vibram's Moon Race Trail sole features sharply cut lugs for extreme traction on any trail, and two parallel grooves give soft flex for mobility.
