Black Ferragamo Loafers Excellent Condition size 6 to 7?

These are Ferragamo Italian made leather "Sport" Shoes. These have a little heel on them as shown. I can't find a size on them. I do see a "36" stamped inside, but that would be a US 5.5 and I honestly don't think they are that small! Comparing them to the brown ones that I have for sale that are marked 7.5, these are the exact same length. However, my size 7.5-8 easily fits into and is comfortable in the brown ones, but I can't get my foot into these! They are stiff and must be more narrow then the others. I am going to guess they would fit a 6.5 or 7, but not too wide. They are in excellent, barely worn condition, but only because I can't verify the exact size I am pricing them very low. Price is firm, please. Thanks!
