I just got back from an Ouray trip and I bought these while I was down there. I'd been looking at them for a while and wanted to try them on before I bought them. I have pretty narrow feet and these fit very well with a thick pair of socks. The weather was pretty mild, so it wasn't the best test for warmth. I noticed on the second day that the bottoms of my feet started to get a little sore, but I'm guessing that's because I hadn't broken them in much yet. I'm also hoping the upper softens up a little because I had a little bit of soreness where my ankle transitions to the top of my foot - again probably because I hadn't really broken them in. They come with a set of ankle gaiters that clip on to the boots, but you have to remember to put them on first before you put your boots on. So far, I am satisfied with them. I look forward to putting them through some harsher alpine conditions in the North Cascades.
