Over glacier-smoothed granite and root-twisted trails, every step in the ACG Mountain Fly is reinforced with an extended toe cap and tough rubber sidewalls. Of course, you're going to get dirty out there—that's just part of the fun—but our durable, crag-inspired traction helps you stay upright and enjoying the adventure. Benefits * Breathable upper airs out quickly when wet, while the semi-gusseted tongue helps keep out debris. * GORE-TEX is placed along the upper to help keep your feet dry. * Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. * Lightweight plate runs from the ball of your foot to the heel for extra support. * Sticky rubber outsole has large lugs that wrap up the toe for durable traction.
