I have 2 pair of Danskos. One white (for nursing school) and a new black pair that I can wear to work now that the white is not a requirement. With my first pair, I opted for the smaller of 2 sizes. While I would not say it was a complete mistake, they are definately less comfortable than my 1 size larger black ones. The front portion of the smaller pair was so tight at first that it gave me a bruise across the top of my foot. Now that they are broken in they are much more comfortable. The larger pair were much more comfortable right out of the box. With those, my heal does not touch the rear of the shoe.
Without a doubt, these are the most comfortable shoes that I have worn for work or play. I wish that my fun shoes were this comfortable. I am so thankful to my best friend for inparting her wisdom to me when I started school. Her experience has saved me many a back ache, I am sure.
