I've owned 3 pairs of clogs (all similar in style) but this is my first pair of Dansko.  I must say they have all been VERY comfortable from the moment you put them on.  I didn't find sizing a problem.  I love the purple pearlized clog and I've had SO MANY nice comments about them.  I've had 2 or 3 other nurses go out and buy these clogs because they loved mine so much and they have all been incredibly surprised at how comfortable they are.  They had all previously worn trainers or other types of shoes.  I will always wear these clogs I haven't found anything to date that matches their comfort and different style choices.  I also found the pricing here competitive.  I highly recommend.
