Agile, comfortable and supportive, the Aerios FL Mid GTX is designed for fast and light hiking on technical trails. The run-inspired design synthesizes with your foot to minimize friction, and the collar adds support and helps seal out debris. GORE-TEX waterproof protection with improved comfort and breathability. Agility, stability and confidence underfoot come from the Vibram® Megagrip outsole, compressed EVA midsole and integrated TPU shank.
