Danner's Kinetic boots are created with durable, quick-to-polish full-grain leather and ripstop ballistic nylon for lightweight breathability. The reinforced heel and metatarsal protection offer increased durability while the polyurethane Fatigue Fighter footbed provides increased cushion and arch support. Kinetic boots are available with a waterproof Gore-Tex lining or a non-waterproof moisture-wicking lining, depending on style. The Danner Kinetic is available in six-inch and eight-inch models in men's sizes 4-12, 13, 14, 15, 16D; 7-12, 13, 14EE.
