Though these shoes aren't very attractive, there comes a time when that's not important any more.  I had some pain from plantar faciitis, and these shoes have been a life saver.  I did some comparing of Sanita vs Dansko, and everyone says these squeak less.  I didn't notice, but I use to have a pair of Dansko, and I think I had the wrong size, since they felt too tight.  These are great.  I just wore them for the first time for a 7 hour adventure in shopping and errand running around the area.  My feet felt great.  I also like how they give me a good inch in height!  These should fit loose on, and have room for your heel to lift with every step.  If they fit snug, go up a size!
