When I first wore these boots I was in the Andes of Peru heading to a base camp at 13,000 feet. We had a late start in the day and the elevation was taking its toll on us, so we ended up hiking the last hour in the dark. It was wet and muddy and my body was exhausted from altitude sickness, but the shoes kept their grip, kept my feet warm, and of all the things I was worried about my feet weren't one of them. Back in the US my town just received one of the worst snow and ice storms in it's history. I wore these boots everywhere as I ran errands and walked around town, and I felt secure from slipping and comfortable walking for the majority of the day. I think they're a great shoe and I'm happy to have them for whatever trekking--mountains or sidewalk-- I have to do.
