When designing the Aerios FL GTX Hiking Shoe, Arc'teryx pulled inspiration from long-distance trail running shoes to create a hiker that delivers comfort, confidence, and support when you're out on long, fast and light hikes across varied terrain. The Aerios features durable Cordura mesh uppers to withstand trail abuse and Gore Invisible Fit technology to fend of moisture from stream crossings and muddy trails. This Gore Invisible Fit technology is comfortable, lightweight, and waterproof ensuring you'll barely notice it as you hike. 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 any conditions.
