The women’s THERMOBALL UTILITY Mid waterproof boot keeps you warm and dry with better protection and better insulation. PrimaLoft ThermoBall synthetic insulation mimics downs best properties and is protected by a nubuck and suede BLC-compliant upper. Baffled PET ripstop offers more protection, as does the injection-molded TPR shell. A Winter Grip outsole and IcePick temp-sensitive lugs bite into nearly any surface no matter the conditions.
