These only come in Euro whole sizes, and Nordies says to size up. I wear a 37 (6.5 - 7.0) in Danskos and TopShop. These booties, at least in the GORGEOUS *garnett* color, seem to be more like a 6.5 and hence are pinchy at the toes for me -- but not enough to go up an entire size. I also ordered the slate gray (arriving Monday) and will report back if they fit any differently. I would say these booties have an average opening at the top, meaning that with my small ankles I would prefer a bit narrower, but they are high enough not to have a flowerpot effect.

ETA: I decided to order again in size 38 -- FOMO. The 38 is out in the slate gray.
