A sophisticated take on Sperry's Mountain-Sider, the Mountain Sox boot is a must-have for fall, winter and even rainy spring days. The sleek upper is constructed from waterproof leather and suede, with elasticated stretch paneling that makes it quick and convenient to slip on and off. Sealed seam and rich welt construction enhance the waterproof nature of these boots, while a Plushstep footbed adds a touch of warmth and plenty of comfort. The lightweight midsole and lugged rubber outsole strike the perfect balance between rugged and agile, so you can move confidently, without feeling clunky. A timeless classic, these boots can be dressed up or down depending on the setting.
