Many have experienced the difference with Danner Sierra boots, an insulated three-season style with full-grain leather and Cordura uppers. This boot is designed for a versatile fit and features a midsole that molds easily to the foot within several wears. A GORE-TEX lining keeps feet dry while also allowing them to breathe, and 200 grams of Thinsulate insulation protects from bitter temperatures. The outside of this boot is also notably durable as it features multiple rear lugs for traction and stability on rough terrain. Each boot weighs 69 oz. and is made in the USA for use by hunters, law enforcement agents and military personnel.
