I am so pleased with these pumps! It took me a LONG time to decide on which pair to buy, especially considering that I wear black pumps more than any other pair of shoes I own, so I didn't want to make the wrong choice. I personally don't find any kind of heel "comfortable" but these are the closest I've found so far, especially for such a high heel. I normally wear a 9 1/2 but I ordered a 9 and they fit perfectly. I haven't had any problems with my heel falling out either. I wore them all day long at work and I really didn't notice any problems or pain. I would definitley purchase these again!
