My first Dansko and I have my usual shoe size which is a bit loose in the back but I think that will work out best so they won't rub my heels raw.  I typically wear a size 7 to 7.5 and I have these in the 37.  Anyway they are SUPER CUTE and comfy!  I have only tried them on so far and will update later after wearing.....

*I have long toes and have noticed that people with short toes will wear the same size shoe, except with a thong sandal where they need a longer shoe to compensate the length in back.  I think this is where reviews get confusing on whether or not a shoe is TTS (in length).
