These Rocky Portland waterproof public service boots are a combination of full-grain polishable leather and nylon. The leather looks good and adds great durability; the 1000 denier nylon is strong to resist abrasions, yet still lightweight. This pair of black public service boots also has a lace-to-toe design on the upper, providing firm support and allowing you greater adjustment in the fit of your boots. To keep you from walking around with wet feet while you're on duty, these men's public service boots have Rocky Waterproof construction. This feature is guaranteed to keep your feet dry. The outsole with rubber lugs provides great traction and flexibility, so the boot soles support you when you stand or walk for hours, even if you move on uneven terrain. These soles are durable, oil-resistant and slip-resistant. Also inside the men's black boots is a non-metallic stabilizer to provide foot support without adding unnecessary metal parts. These Rocky Portland Lace-to-Toe Waterproof Public Service Boots are made from hard-wearing materials and have a great fit. If you need new public service boots, these waterproof public service boots from Rocky are a great choice.
