Muck™ has combined high safety standards with technology that keeps your feet cool and dry without adding cumbersome weight. XpressCool™ linings pull moisture away and redistribute it. This enhances evaporation and creates a cooling effect. The etc® Anti-Friction sock liners reduce perspiration-causing friction and provide antimicrobial protection that eliminates 99% of odor-causing bacteria. High-grade rubber exteriors of neoprene layered with Spandura® protect against wear and abrasion. Triple-reinforced uppers, quadruple-reinforced heels and Achilles reinforcements offer superior foot and calf protection. Vibram® outsoles are outfitted with large toe pads to increase traction, the broad lugs improve surface contact and the grooved heel pads deliver solid traction in slick conditions. The 4mm CR flex-foam booties have four-way stretch for superior fit. Steel shanks offer arch support. Imported. Height: 12". Average weight: 4.5 lbs./pair. Men's whole sizes: 5-16. Color: Brown.
