Love these! Good quality and elegant shape. I have a problem with pumps slipping off my feet when I wear tights. I bought these in my normal size 6 and a size down, 5.5, to compare fit. The 5.5 was perfect. (these run a bit big, I'd rec going a half size down)The back of the shoe kind of hugs the heel, so they stay on even with tights. I will definitely be buying more work shoes from here in the future.
