I don't know a lot about these, other than they were made in Chiina, and have that odd hook and loop fastner. These are labled 45, which would be far too large to be size 11, but they fit lite a 10.5 to 11. They have a bow on the back of the right heel, and on the toe of the left heel, whch is reminiscent of a designer who's name escapes me right now. They have a 4" (110mm) heel. I believe these might be wedding shoes.
