Made in the USA, the Powerline is a true lineman\'s cold weather work boot. With an extra-strong steel shank and a reinforced, supportive midsole, it\'s built to climb and not fatigue the foot. The combination of alkali resistant, waterproof full-grain leather and a GORE-TEX® liner keeps you dry in the toughest conditions. 200 grams of Thinsulate� insulation keep you warm. As for durability, double-thick leather protects the lineman\'s foot where wear and tear most often occurs, and in the unlikely event you find yourself needing a new pair, the Powerline\'s stitchdown construction makes them recraftable.
