I emailed him that question, and was told it was an 11.5 American. But to be honest, I'm not entirely sure he knows that for certain. I should have asked for measurements. I asked for a picture of the sole, and he just said "I'd rather not. I've moved on to other things." Psssh. Not the nicest guy in the world. btw, anyone know what happened to this seller? If memory serves me correctly, when I bought something a year ago, I was helped by a very nice woman. She said she got all her items by donation, and donated the money and made quilts for cats and dogs in shelters. Is she still associated with this ebay id?
