These Danner Crafter 6in. Waterproof Nonmetallic EH Work Boots are ASTM rated to protect against 75 lbs. of impact/compression, so they're perfect for wearing on jobsites with heavy or falling objects or on hiking trails strewn with tree roots or rocks. These heavy-duty boots feature the Danner Dry system with durable, oiled, waterproof nubuck leather uppers and breathable waterproof liners, so feet stay dry in wet conditions. The lace-up design that allows a custom fit. The Danner Comfort dual-density footbed system features a 7mm cushion in the forefoot and a 15mm cushion in the heel to provide comfort, impact resistance and air circulation with every step you take. The broader toe style 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. A great work boot choice.
