The ARCTERYX Bora2 Mid GTX Hiking Boot combines the agility of an approach shoe with the stability and protection of a mountaineering boot. Based on a close study of the footG??s dynamics, the resulting boot combines an outer shell and an inner liner in a single streamlined structure. The long-wearing outer is a laminate of tough textiles; its one-piece construction eliminates seams, creates larger breathable surfaces and is snag- and abrasion-resistant. A removable waterproof/ breathable stretch GORE-TEX liner with an insulated option adds versatility when your objective dictates multiple days and variable weather. Durable Vibram soles feature a climbing zone.
