I'm not sure why so many people complain that they don't provide the exact lift they claim. The shoes would look silly past a certain point if they attempted to add too much. All I know is that I'm taller than I've ever been wearing these shoes and they are stylish enough to wear frequently. I disagree with people who say they run small because I ordered my normal size and the heel is a little loose. It's actually kind of nice because I can slip them on and off easily, but I definitely wouldn't want a bigger size.
