Work comfortably in the Wells Lamont Men's Copper-Infused Polyester-Blend Work Crew Socks. Cupron anti-fungal pro fibers are EPA-registered to kill 99% of athlete's foot fungus after 12 hours of wear. This technology is clinically proven to improve skin texture. The socks are designed to wick sweat away, keeping your feet dry while you work. The Cupron-enhanced fibers also serve as a great defense against foot odor. These work socks feature a reinforced heel and toe as well as an Achilles heel pad for added protection and comfort. They're the ideal pair of crew socks for all-day wear, heavy-duty tasks, construction, automotive/mechanical work, equipment operation and more.
