Love them! Glad they are growing on you & hope they stretch out a bit too.
So I called my SA about the too tight Noir RS's as soon as NM opened. He found another 7 1/2. I purposely wore my very comfortable black patent and blush, which I wore for the first time yesterday so he could see the difference with the Noir. He had asked if I measured the strap, I didn't before I called but did it out of curiosity. The straps were at least 1/4 inch shorter on the Noir! Anyhow, I put the new 7 1/2 Noir on and they fit perfectly and comfortably, just like my other pair. Then I put the old one on the other foot. He could see the strap difference immediately, how tight the bottom was with no leeway, and I could only fasten the strap on the first hole. He said he will talk to the manager and most likely they will be sent back. He believes they are defective. Anyhow, I'm SO glad I went back and have the comfortable ones on now in the pic

Here they are.....
