I bought this beautiful sandal on line because  the store where I had seen it did not have my size.  When it arrived I could not get my foot into it.  It is an inch shorter than my other 7.5s.  I may reorder it, but first I plan to try the larger sizes on in a physical store to get some idea of what size I wear in this sandal.  My guess is 8.5 or 9. I could not answer any of the other questions, as I could not get it on.
