I wear size 9 1/2- 10 wide. These shoes were the perfect look, although a little bright of a silver. I wore these to a wedding and the strap kept falling off my heel. In between the wedding and reception, we stopped at a CVS and I purchased those Dr. Schols silicone grip strips, but even with those the the strap refused to stay on. I was hugely disappointed.
I wear wide mostly for my toe box and perhaps my heel is normal size and that may be why they were too big. Still there was a small elastic section on the strap, which should have made it automatically adjust to my heel size, but the elastic was not very springy. Sort of stretched out.
One more thing if you wore these without stockings they may work for you. However, for me silver is a winter holiday type choice and I would never go without nylons in the winter.
