The Danner 6" Kinetic GTX SZ is a rugged boot that delivers long-lasting comfort and support. A GORE-TEX lining provides waterproof protection, while promoting ventilation to keep your feet dry and comfortable. These boots are built on a Danner Kinetic outsole, a low lug, multidirectional outsole that maximizes traction and surface contact, ideal for sudden acceleration from a resting position. The upper is made from a blend of nubuck leather and 1,000 denier nylon that is waterproof and easy to maintain. A cushioned polyurethane midsole provides additional support and comfort, and the speedlace fastening system delivers an exact fit.
