These are a size 8 US but I’m listing as a size 7.5. These were only worn two days on a trip to Switzerland (Matterhorn & Jungfrau). I found them to be a bit short and immediately ordered the 8.5 because I love them so much. I normally wear 7.5-8 in shoes and, for reference, I have 3 pairs of the Joan of Arctic III Chelsea in a size 7.5 that I live in every fall/winter day. So IMO, these boots run small and would work better for someone who is a 7-7.5 in shoes. Questions? Leave a comment below!
