I bought these, and never wore them because they're a little large for me. They're gorgeous and completely unworn. SIZE 39. (Listed as 8.5) From Emme Parsons website: "A modern fisherman slide with a directional square toe and interlocking front strap, the small stacked heel, and calfskin finish of the Leo lends a sophisticated finish to contemporary tailoring, whether styled with skirts, pants, or shorts. Please note that these shoes are made from vachetta, a vegetable-tanned calfskin leather and they will need to be broken in on most feet. Over time this high-quality leather will change its shape and mold to your foot for optimal comfort." Original Listing with sizing: https://www.emmeparsons.com/products/leo-in-luggage
