The Corvallis offers a blend of comfort and durability. Designed for workers who spend long hours on their feet, the Corvallis provides features typically found on much heavier boots, like triple-stitched seams and a non-metallic safety toe. By incorporating advanced materials and weight-saving design, Danner made the Corvallis feel more like an athletic shoe than work boot. The non-metallic safety toe won't conduct heat or cold to the foot, and meets or exceeds ASTM standard F2413-11 M I/75 C/75 EH. Electrical hazard (EH) footwear is manufactured with non-conductive electrical shock resistant soles and heels.
