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.
