The heavy-duty LoggerMax 2117 is built atop an ultra-durable GoodyearA(R) welt construction platform for stability, with an aggressive VibramA(R) lug sole underneath that delivers best-in-class slip, oil, heat and chemical resistance. Features include electrical hazard protection and a non-metallic safety toe that preserves the family's classic profile while reducing weight and improving performance in cool conditions. The advanced Red Wing waterproofing with lightweight 3M Thinsulate(TM) Ultra insulation also helps keep you working comfortably when the weather gets cold and wet. The 9-inch leather upper extends higher up the calf for enhanced ankle support and excellent traction over uneven terrain.
