Dansko sizing

[Quota]

So I'm starting nursing school next month and need all white and appropriate shoes for school. Went and tried on a number of the recommended brands and settled on dansko XP pros but they didn't have all whites at the store. Found the best pricing I could online and ordered the size that fit best in store. New shoes arrive today and they are too snug, supposed to be a bit loose and my toes are pressed against the front and my heel touches the back. I know the guy at the store said they all fit a bit differently so I'm conflicted if I should exchange them for a larger size or just another pair in the current size? Both seem like a bit of a risk of ending up with too big or too small again.

Suggestions?

41s arrived today and feel kinda big but that's better than small. Should be fine once I get my own custom orthotics and inserts into them.
