A classic winter boot redesigned in a more versatile and warmer package, the Columbia Men's Bugaboot Plus Snow Boots take comfy feet to the next level. Stepping it up, the Bugaboot added exclusive Omni-Heat insulation and thermal reflective technologies for an even warmer foot and toasty toes. Like a space blanket for your feet, Omni-Heat reflects your own body heat back into the boot, amplifying the effect of the insulation. Its waterproof leather upper gives sturdy support, while articulation at the collar enhances freedom of movement. The new super lightweight full-length Techlite shell that is near half the weight as previous versions is skinned with TPU-coated leather for durability and abrasion resistance. The Columbia Sportswear Men's Bugaboot Plus Snow Boots also features a dual compound Omni-Grip lug outsole that is temperature sensitive, varying hardness depending on terrain surfaces.
