I went by the other reviewers and bought these slippers 2 sizes down. Usually I buy size 6 for men and it works perfect for me. My 11yr old kid loves these headphones! Love this one. Best option i can find so far. Not sure we will be able to hang in our camper as the smell is that strong. Its small, and doesnt look like much at all. Look great with any outfit, shorts, jeans or dresses. 00 for the shoes and 40. I have a wide foot, and they are just about perfect.
