This Rocky IronClad work boot has a kiltie -a piece of fringed leather placed down by the bottom eyelets- to keep external items from coming into contact with the interior; such as: small twigs, pebbles, grass, mud, etc. If this is not your style or you would like the boots to look a little more casual, the kiltie can be removed very easily. These work boots not only look great but also provide excellent protection. They have a steel toe construction that meets ASTM F2413 I/75 C/75 Protective Toe Classification. These protective-toe work boots also offer Electrical Hazard protection which insulates the outsoles from the ground; amazingly helpful at hindering the conduction of electricity, which is ideal if you work around electrical equipment. Material: Leather.
