I have the Dansko Professional clog before.  There are great.  I was looking for something a little different, and I looked at the tigers eye and other more unconvential colors.  I just felt they were not going to give me much mileage with my wardrobe.  So I finally decided on these.  The "grey" color is really more of a black, and the prism type color is just awesome.  I held this up to all the clothes in my closet, and really, they would go with anything.  Overall, I am very pleased.  I have been buying more and more clothes and shoes from Amazon, as it seems to be where the deals are.
Nice product, free shipping, good price.
