I just received these shoes in the mail today and put them on immediately. All I can say is WOW!!!!! I walked around my house for two hours while doing dishes and cleaning up and they felt great! The look of the shoe is beautiful (perfect for work and weekend) and my heel did not slip at all (which usually happens to me because I have narrow feet). I would recommend purchasing a 1/2 size larger than you usually wear in pumps. I usually wear an 8 in "Jessica Simpson Collection" shoes (when I buy them in stores) but I got an 8.5 and they are a perfect fit! I couldn't be happier and can't wait for summer to wear them!
