These Rocky Waterproof 11in. Nail Guard Puncture-Resistant Steel Toe Wellington Boots are true heroes. With a rich full-grain leather and 600 denier nylon uppers, these boots feature ASTM certified steel toes that protect feet against 75 lbs. of impact and compression, while the oblique toe style provides extra room to prevent cramping. These boots are ASTM certified to protect feet from electrical hazard, and the oil- and slip-resistant sole is also puncture-resistant to prevent injury from nails or other sharp objects that would pierce the sole of an ordinary work boot. The Rocky waterproof system combined with a mesh moisture management lining keeps feet dry regardless of natural precipitation or leaking water. Fiberglass boot shanks provide arch support to keep you steady on your feet all day long. Lightweight EVA midsoles and Rocky Air-Port beds provide cushioning impact resistance and help create a more lightweight steel toe boot. Cement construction ensures durability. An excellent choice for wearing at a jobsite fraught with moisture, machinery, sharp objects and falling objects.
