Socks absorb sweat and provide a comfortable, protective layer between workers' feet and shoes. Protective socks include CarbonX socks and knit Nomex socks. CarbonX is an extremely durable material that resists extreme heat, direct flame and scalding liquids. It breathes well, has good flexibility and will not ignite or burn. Knit Nomex socks are very strong and durable. They resist cuts, abrasion, fire and temperatures up to 2,000 degrees Fahrenheit.
