Black ankle boots. 5 times used

It says size 6 but I think it fits more someone size 6.5 or 7 because I’m supposed to be 6 and they’re big in my foot. I used them 5 times for a week in New York but I don’t need them anymore. They’re perfect, no details or damaging in any way, just as new, I’m just selling them because I don’t use those type of shoes.
