The Columbia Men's Bugaboot Original Omni Heat Tweed Full Grain Boots eat rocks, mud, gravel, ice, and anything in between for breakfast. These rugged boots are crafted with an oiled, full grain leather upper over thermal reflective liners and seam taped waterproofing. This means that as you face the elements, you're protected and stylish. With 100 grams of synthetic insulation, your toes don't freeze off as you hike up an icy trail. The Techlite EVA midsole provides long lasting comfort, superior cushioning, and high energy return, which absorbs shock and allows you to run and jump over jagged rocks with ease. They also have a durable lace closure and an Omni Grip non marking rubber sole.
