Blundstone Super 550 SeriesMade 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.
