Full-Grain Leather Upper: To ensure its quality, we put our leather through six different tests before making our selection. Our full-grain leathers are the strongest and most durable form of leather.GORE-TEX (GTX): 100% waterproof and breathable, GORE-TEX liners ensure that no water gets in, while allowing sweat and moisture to get out.Speed Lace System: Our special hardware allows you to tighten from toe to top with one swift tug for a secure, tight fit.400G Thinsulate Ultra Insulation: High-performance insulation that keeps you warm in the snow and rain without weighing you down.Electrical Hazard (EH) Protection: Electrical hazard (EH) footwear is manufactured with non-conductive electrical shock resistant soles and heels.Composite Toe (NMT): Our composite toe is non-metallic, does not transmit heat or cold, nor will it set off metal detectors. As expected, it meets or exceeds ASTM F2413-18 M I/75 C/75 EH standards.90º heel: Added safety for boots used on steep terrain, climbing in and out of equipment, and use with certain tools.Vibram® Vicious Outsole: Oil- and slip-resistant with a low-profile 90° heel.Danner Trailguard: Lightweight and supportive, the Trailguard TPU shank provides stability and underfoot protection on rough, uneven terrain.How It Fits: The DLE-01 last was designed to be an extension of the foot with superior forefoot and heel capture, stability and a more anatomical shape for comfort. The additional space in the toe box allows the foot to naturally react when bearing a heavy load or changing directions laterally in high intensity environments.365-Day Warranty: If you suspect your purchase isn’t up to our unrelenting standards, or is defective in any way, we want to make things right. We offer a 365-day warranty across our entire footwear and apparel lines.
