I'm told Danskos are handmade, which is why the fit will vary wildly from pair to pair.  I have the black tooled in size 40 and they are by FAR the most comfortable shoes I have EVER worn.  I also have another pair of Danskos in a size 40 that are much larger and while comfy standing on my feet all day, not nearly as good as my black tooled ones.

If you are on your feet all day, you NEED Danskos.  Your feet and back will thank you 100 times over.  But the size variations make it a must to try on the pair you want to ensure you get a proper fit. Sorry Amazon, but do NOT buy them online.  You just can't ensure proper fit that way since the size is not consistent. Your heel should slip out of them when you walk, but the top should be a little snug on the top of your feet.
