My Army infantry unit operates in extremely rugged terrain in a very austere, high altitude environment in Afghanistan. We are authorized to wear Merrell Moab's, and we swear by them. We spend a lot of time on foot, and these boots make all the difference in comfort, enhanced agility on rocks and steep hills and they allow us to move long distances much more quickly. We frequently cross wadis and streams, with water up to our waists, and the Moab's dry out quickly. We have found them to be very durable and up to the challenge of combat in one of the top roughest locations in the world. Our only regret is that we did not have them in prior deployments. We wish we could acquire them more easily over here, but they take about 3 weeks to ship to us.
