I bought these for skiing and was very happy with them as they kept my feet warm and dry all day. In addition to the 20 or so full days skiing, I also took them snow hiking on one occasion and when the weather started warming up, took them on a few bike trips. They performed well under all conditions from below freezing, to cold and wet and even still comfortable in temperate weather. With all the abuse, they are still in excellent condition with no holes or even hints of a hole. I would probably look to buy more next winter, but I probably won't need to as these still have plenty of life left in them.
