I purchased these with little hesitation after owning a pair of Jessica Simpson nude slingbacks I loved.  They fit perfect, which is hard to find since I have small and narrow feet (5.5).  They had their run and it was time for a replacement, I found these and they were the exact color and since they were Jessica Simpson.  Once I recieved the heels, they looked great and fit pretty well, however after only half a day of wearing them (I typically wear heels 4 days a week, 6 hours with a total of approx 1.2-2 hours walking around).  The bottom opening which hits past your toes cuts into the outside of my foot.  I was in such pain, and such disappointment since I was counting on Jessica Simpson being comfortable.  I purchased some insoles I thought may help, but they became a pain to reposition. I would not buy these without trying them on.  I have used rubbing alcohol on them and stretched them out but it has helped only mildly.
