I bought these over boots for an AK trip a couple of years ago and have only used them during that two week trip. They are still in great condition but have a few scrapes in the heel from crampons. These are a size small which should fit everywhere from a 37-40. They retail for $160 but am willing to part with them for $100. Let me know if you have any other questions.
