As the third generation of the Zamberlan Guide, the Guide Max is an extension of the Guide Lux by adding GORE-TEX laminated calf leather lining around the collars and entire inside of the boot for increased comfort and durability. The Zamberlan Guide Max is the ideal hiking boot for all-season backcountry use in rugged terrain where the ultimate in durability, support, and handle-anything-and-everything protection is required.
