I do have a pair. When I first tried them on, they seriously felt like bricks. Anything that felt that awful had to be made that way for a reason. So I bought them and wore them the next day for 12 hours at work. They turned out to be wonderful and well worth the investment b/c I've had them for 5 years and they still look great.
Another shoe I really love, is by NurseMates. It's called the Bryar and it comes in all white. It's a lot more pillow-y, if you can't get over the brick-like feel of Danskos. They are also slightly more affordable.
