Few places challenge insulated boots like the deep cold of winter in Minnesota's Boundary Waters. And this high-cut double boot measured up. "I usually get cold feet while snowshoeing, but these boots kept me toasty at 0°F," our tester reported. Credit a three-layer liner that consists of wicking polypropylene closest to the foot, then insulating wool felt, and finally a "thermal foil" that traps body heat. Traction was good on packed snow even without snowshoes, thanks to aggressive outsole lugs.
Hours of hiking in sloppy snow eventually wet out the waterproof suede-and-nylon uppers, but they didn't leak; the seam-sealed construction prevented moisture from dampening the removable liners. As expected in this category, fit is roomy and arch support mediocre. Note: The bulky construction enhances warmth, but the boot may not fit all snowshoe bindings. Best for medium-volume feet. $90; 4 lbs. 1 oz. (men's 10) Kamik.com
