Purpose-built and ready for combat, Rocky S2V GORE-TEX Waterproof 400G Insulated Tactical Military Boots are designed to provide maximum protection from harsh winter weather. These waterproof combat boots feature 400 grams of 3M Thinsulate Ultra Insulation that traps heat to keep your feet warm in sub-zero temperatures. A PTFE-coated leather and GORE-TEX fabric upper repels mud, snow, and ice, while a Dri-Lex liner with Aegis Microbe Shield keeps your feet dry and free of disease. Unpredictable surfaces are no match for a high-walled Vibram outsole with deep lugs that deliver unbeatable gripping power on any winter terrain. Rocky S2V GORE-TEX Waterproof 400G Insulated Tactical Military Boots are GSA and Berry Compliant and are proudly made in the U.S.A.
