When it was designing the Aerios FL GTX Hiking Shoe, Arc'teryx pulled inspiration from long-distance trail running shoes to create a hiker that provides support, comfort, and confidence when you're out on fast and light hikes on varied terrain. As the miles add up throughout the day, the durable Cordura mesh uppers withstand the abuse of the trail while the Gore Invisible Fit technology keeps your feet dry. This Gore Invisible Fit technology is comfortable, lightweight, and waterproof so you'll barely notice it's there as you charge through shallow stream crossings and muddy trails. Agility, confidence, and stability come from the TPU shank in the midsole and the durable Vibram MegaGrip soles that keep you hiking fast and light on shifting terrain in the high alpine.
