New-never worn Timberland takes their legandary Super Boot to the the next level with the Winter Extreme GTX 8" Boot. Sporting a more tactical design than the classic Super Boot, the Winter Extreme still boasts the durable and rugged construction that keep Alaskan winters at bay. The 8" upper is made from premium full-grain waterproof leather that is lined with a GORE-TEX membrane that wicks away moisture while keeping the foot completely dry. 400 grams of PrimaLoft insulation keeps heat turned up while a Vibram rubber lug sole conquers any terrain.
