I ordered a pair of these because they were one of the brands that showed up as the best sandal for someone with plantar fasciitis (heel pain sufferers). I ordred a size 40 which normally fits me in any other brand I have tried. This particular shoe seems to run small, because although the 40 fit (just) I was very close to having my heel or toes hanging over the edge. I don't know if the sizing is the same for all styles of Dansko, but the next time I order this shoe it will be in a 41. The width was fine.

The shoe itself is very attractive and I wore them out shopping to see how they managed with my heel pain. The arch support was good and my heels felt fine, though I did feel I was having to concentrate to keep the shoe on my foot as I walked. The padding in the shoe is excellent, although I did suspect with extended use the upper may cause some blisters.
