I got a size slightly bigger than usual (40 instead of a 39) because I’d seen other’s suggesting size up. Not sure if the 39 still would have been ok but figured it would be better to have slightly bigger than slightly too small and wear thicker socks if needed. They do have a little extra space but haven’t got blisters and have been comfy in them in both socks and stockings on the two occasions I’ve worn them. Love these boots so much!
