These Danner Crafter 8in. Waterproof Nonmetallic EH Work Boots are ASTM rated to protect against 75 lbs. of impact/compression and against ground-conducted electrical hazard. Perfect for wearing on jobsites with electrical equipment and heavy or falling objects or on hiking trails strewn with tree roots or rocks, these boots will also keep feet dry. The Danner Dry system features durable, oiled, waterproof nubuck leather uppers and breathable waterproof liners. The lace-up design allows for a custom fit, while the Danner Comfort dual-density footbed system features a 7mm cushion in the forefoot and a 15mm cushion in the heel to provide impact resistance and air circulation with every step you take. The broader toe box provides spacious comfort, while Airthotic® heel clips supply maximum heel support. Fiberglass shanks ensure solid arch support, while Danner Crafter rubber outsoles feature 90° heels that bite into ladder rungs, so you can climb confidently. Outsoles are also oil- and slip-resistant for traction and durability. At just 59 ounces (approximately 3.6 lbs.), these heavy-duty boots are lightweight, so they won't slow you down.
