The Aerios FL GTX is agile and comfortable, with the support needed for hiking fast and light on technical trails. Inspired by long-distance trail running footwear, the design synthesizes with the foot to minimize friction, and agility, stability, and confidence underfoot come from the Vibram Megagrip outsole, compressed EVA midsole and integrated TPU shank. Waterproof protection comes from a GORE-TEX membrane featuring improved comfort and breathability.
