The Rocky Retraction Waterproof Work Boot is a versatile boot designed to go wherever the day takes you from outdoor terrain to indoor work. This men's work boot stands out. The EVA, rubber outsole has traction for outdoor work, but also is designed to be oil- and slip-resistant. With many work boots for men, the design focuses on outdoor work only. Many jobs take you across smooth, slippery floors, as well as the muddy, uneven ground. This footwear is an all-terrain boot created to go indoors and outdoors. Material: Leather.
