Rocky Alpha Force Waterproof Public Service Boots are made with black full-grain leather and 1000-denier nylon fabric. These lightweight, strong fabrics hold up even in the most extreme working conditions. These boots have been built with Rocky waterproof construction; this creates a barrier that is guaranteed to keep water out, so your feet will remain completely dry. The Air-Port footbed is made from polyurethane and absorbs shock, but always reverts back to its earliest shape. The cushion footbed specifically targets your heel and metatarsal ridge, giving you support and comfort.Specifications and Features: Guaranteed Rocky Waterproof construction Non-metallic stabilizer Full-grain water-resistant leather Oil- and slip-resistant, non-marking RigiTrac molded EVA/rubber outsole Rocky Air-Port cushion footbed Lightweight 1000 denier nylon 6 Inches in height
