Agile, comfortable and supportive, the Aerios FL Mid GTX Boots are 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 with GORE Invisible Fit Technology delivers full 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.
