The Muck Boot Chore-Resistant Tall Work Boot is a huge step forward in slip-resistant footwear. This boot will keep workers vertical on some of the slickest surfaces that face them on construction sites, in mines, on the farm, or in factories. The Honeywell RDR rubber exterior resists chemicals and most oil-based fluids for maximum protection on the job. The 5mm neoprene upper is warm and comfortable, while the breathable airmesh lining keeps feet cool in the heat. The steel shank offers additional support while standing on hard surfaces for long periods of time. Triple toe and quadruple rubber heel reinforcements ensure long-wearing durability. Tested on slippery surfaces including steel and ceramic tile, the Chore V-Wave outsole with Honeywell SR compound earned an improved slip-resistance rating of 20% in 2015. Comfort range: 0° to 65° F. Medium width. Imported.
