Being a Hairdresser, I am on my feet all day, every day and these shoes are life savers!
(Danskos speak for themselves)
However, I want to write a helpful review that will hopefully answer some others' questions.

First off...I choose to wear the clog because it is all enclosed (for safety as well as cleanliness).  Especially at work, I don't want hair all over my feet.  The hair just slides right off and they always look clean. For safety reasons I like a closed toe shoe as well. They can tend to look a little "grandma-ish" if you don't style them well.  I love bootcut jeans or rolled up skinnies with them. With a little creativity you can make anything look cute.
  As people have said, they should be worn with socks.  My friend didn't wear socks with hers and YES, they DO stink after a while (like any shoe would I assume).  I wear a NO Show sock on days I wear skirts/dresses and even shorts.

The color is perfect.  They look just like the picture. The brown is not too solid, so it makes them have a more rustic feel, like a cowboy boot type of color.

FIT:  I wear an 8 to 8.5 shoe size and the 39 fits perfect every time.  You are supposed to leave a bit of room behind your heel, so if they fit like a glove, I'd go up a bit.  You don't want them tight.  Don't forget to guage the fit according to the socks you will wear.

You might have to break them in. I would wear them for an hour or two at a time for the first couple of weeks to ease in if you aren't used to a really good, supportive shoe like this.  I urge you all to buy some Danskos, they have really changed my life, and I like to keep a good product around.

I don't have back pain, or foot pain, and they have such a variety now, you can find them to wear with everything.
