The Corvallis offers a rare blend of comfort and ruggedness. Designed specifically for workers who spend long hours on their feet, it provides features typically found on much heavier boots (triple-stitched seams and an available non-metallic safety toe, for example). By incorporating advanced materials and weight-saving design, we made the Corvallis feel more like an athletic shoe than work boot. 100% waterproof and breathable. Electrical hazard (EH) footwear is manufactured with non-conductive electrical shock resistant soles and heels.
