These are the viral "MyTribe" boots from Australia in size 41 EU / US 10. I bought them and they are too big and to pay to ship them back for exchange isn't worth it. I love them. But even with thick socks they won't work fro me. They have never been worn. Please see the sizing chart in the description for more details. I consider them NWT but they came with no tags attached. They are in the original box.
