The Chore Cool work boot is suitable for year-round wear in most climates, taking you from 40 degrees to 95 degrees. It features etc® sockliner technology to reduce heat-causing friction and a breathable, moisture-wicking XPressCool™ lining for cool comfort. A steel shank provides arch support and puncture protection, and the heel and toe areas are solidly reinforced for workplace safety. A new Vibram outsole (exclusive to Muck Boots) features a shallow lug pattern that sheds mud and debris while keeping the wearer secure on slick, wet surfaces. The tough but flexible Spandura® shaft offers excellent abrasion resistance and reliable leg protection.
