I'm a devoted Nine West customer but am often disappointed in their platform heels as the sizing can be all over.  I originally bought these in an 8.5 and ended up exchanging them for a 9.  They're a basic black platform heel with a bit of glitz.  They aren't as arched as some heels which makes wearing them for longer periods more comfortable.  I wore these out of the box for several hours with no complaints.  Overall, I'm pretty happy with these :)
