The heavy-duty LoggerMax 2117 is built atop an ultra-durable Goodyear® welt construction platform for stability, with an aggressive Vibram® 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™ 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.
