Ideal for trail running in wet or mixed conditions on unpredictable terrain, the Men's Norvan VT GTX from Arc'teryx delivers GORE-TEX® protection, enhanced climbing and scrambling capabilities, and excellent traction and comfort. The adjustable 360° support system switches from a higher volume run mode to a precise-fitting climb mode. Fixed Adaptive Fit Technology wraps the foot and seals out debris. The custom Vibram® sole combines a sticky Idrogrip forefoot for traction on slickrock and wet trails with a Megagrip compound for durability.
