Boot Height: Approx. 11'' Tall. A great all-around recreation pac, the Alpha Ice King is waterproof and ideal for ice fishing, snow machines and other cold weather activities. Built on a soft-shell construction with an all-leather upper over naturally insulating neoprene, this boot is both lightweight and durable. A 4mm wool-felt midsole and 800 G. Thinsulate Ultra Insulation deliver outstanding warmth and comfort. Radientex lining reflects heat back toward the foot while wicking away moisture.
