"I wore these to a black tie wedding that went for 9 hours of standing and dancing. I was expecting my feet to hurt a lot more than they did. I didn't once need to take them off or slip into ballet flats and they looked so sexy and stunning. I felt like they were right out of Saturday Night Fever but the 2013 edition.
One thing I will note is that the difference from the size 9 to size 9.5 was negligible. They ended up working out, but if your feet are on the cusp I would recommend a half size up, especially since Caparros run on the narrow end.
