Designed for tough industrial environments. Made with a multi-ply manufacturing method. Every boot is dipped with a neoprene coating and sealant, so the foot is surrounded by a layer of 100% waterproof and chemical resistant neoprene for optimum protection and extraordinary comfort. Neoprene rubber will outwear standard rubber boots in solvents, caustics, hydrocarbons, oils, fats, and acids. Hand-layered construction allows for a soft flexible upper and more material in the toe and hell contact points, for optimum comfort and protection. Safety-toe styles meet ASTM F2413 M I/75 C/75 EH, for steel toe caps and electrical hazard protection. Snugleg last design hugs the foot for all day working comfort. Removable polyurethane contour cushion insoles for maximum comfort. Dense fabric liner for easy on and off. Also wicks moisture and condensation. Chevron or Safety-Loc outsoles offer abrasion resistance and provide excellent slip resistance on wet-contaminated or wet-clean surfaces, respectively. Steel shank for added arch support.
