Aravon Erica Dark Blue Faux Suede Slip-on Loafers

I bought these for jury duty from a local thrift store and never really wore them. I was in a hurry and made the mistake of not trying them on in the store, so they are too tight on me. It looks as though the previous owner took out the lining on the back-side of the tongue, so I have no idea what the official size is. My guess is that these are either a size 9.5 or smaller because I only wear a size 10 and above. Smoke and pet-free home.
