I am a loyal Dansko shoe owner, and these do not disappoint!  Some other reviewers mention ordering down a size.  I wear a 42, and did not order down.  The heel slips just like it would on a normal clog, and I have had zero issues with blisters or an ill fit.  The straps are holding up after a month of wearing them about 3 timess a week for a 10 hour workday.
