5 or 11 in some shoes, so I ordered a 10 because adidas is always slightly larger and they fit amazing. Perfect fit, I wear a womans size 18/20 and this is my favorite nightgown. Another good Rockport find! I ordered 7/8 as I normally where 7. Makes me think Im blind and cant read braille. Literally cannot fit this on the stand. The audio controls can get annoying, left to increase and right to decrease. After wearing them for a few days, the fake leather snapped in half. The only way to safely take it off is by pushing up through the bottom. Not deal breakers since you can see in the video I posted how easy and convenient it is to change your lighting.
