I purchased these Star Wars themed organic cotton shoes back in 2020. They are listed as a size 37 European. I wear a 6.5 in U.S. and these felt good on me. The box does say US size 6! I had bought these for our kid when I bought a pair for myself but he never wore them. These shoes are NO LONGER MADE and these are pristine. They even have the original packaging inside the box. I do not accept returns so please ask any questions before purchasing. Coming from a smoke free, low scent house hold with a dog. I have shipping set as USPS Priority Mail. This comes with insurance up to $100 in value so this is my preferred way to ship.
