The Oboz Bridger 7in Insulated B-Dry Boot is built to keep pace with the day, whatever that day asks of it. 200 grams of Freeze Guard insulation holds warmth through a slow, casual walk without overheating on a harder push through the snow. A Trail Tread Polar rubber compound grips icy, frozen ground, all in a package slightly shorter and lighter than the brand's 9" women's model. What Our Gearhead(R) Experts Are Saying:"I broke a sweat postholing uphill for twenty minutes and never had to unzip a layer, then stood around at the trailhead afterward and stayed just as warm. It's the first winter boot that hasn't made me choose between overheating or freezing depending on how hard I'm working."
