Women's size 5.5 US Motorcycle fashion boots

Hello! I bought these online when I got my new scooter, and they were listed in European sizes. I used a conversion chart online, and either the chart was wrong, my order was lost in translation, or or I just plain ordered the wrong size. Anyways, I wanted a US women's size 7.5. I let my friend with smaller feet try them on and she said they're a women's US size 5.5. I paid $80 for them and they are high quality, never worn outside. My loss is your gain!
