Fast, rugged and ready for whatever wild comes your way. The updated ACG Mountain Fly 2 is built to take you to the top. Over glacier-smoothed granite and root-twisted trails, every step is reinforced with an extended toe cap and tough rubber sidewalls. Don't worry about pushing your limits either: The breathable upper helps keep you from overheating and airs out quickly when wet. For extra comfort and support, there's a foam midsole and lightweight plate running from the ball of your foot to the heel. We also made it easier to get on and off, thanks to a semi-gusseted tongue and lace toggle for quick adjustments. To finish it off, crag-like traction (inspired by mountain bike tires) helps improve durability so you can continue enjoying the adventure.
