These are very pretty shoes, but they seem to run slightly smaller size-wise.  I felt comfortable ordering them because I'm (usually) a perfect size 9.5M, especially with the Nine West brand.  Unfortunately, these are tight and uncomfortable.  I'm keeping them in the hopes that they will stretch out a little.  Like other reviews have noted, I've noticed that my heels tends to slip out of the shoes even though they're tight around the toes and ball of my foot.  I did purchase heel grips, but I think the shoes would be way too tight if I tried to put them in.
