Size is a 9 but I’m a size 8.5 and they still fit tight. If you are a size 7.5 they will fit better. I think they are boy or men size. Not sure. They were a gift so only used twice. Inside has a liner thermal that can be removed. They are really great boots. Wish that fit. Priced to sell. Please take note that I am listing as 7.5 women although they say 9. They may even fit good as a 8 but no bigger. You can research the brand. I do t want to have to do a return. Thanks.
