Made for thrill-seekers, explorers and those who wander off the beaten track, the  Super 550 Classic boot is made with water-repellent, prime leather uppers and designed with more bells and whistles to offer the ultimate in comfort and durability. Designed for comfort and shock absorption, finer leathers and the soles are a bit sturdier. The inner leather lining also gets an upgrade from the basic 500 Series.
