.... you wear a size on the very low end of the size range and don't mind a slipper that slips! For my mom, who wears an 8.5M, I ordered an L per the size chart. The fit was too tight. She also needed a slipper with more traction than this one. Not good if you're looking for a non-skid slipper. We concluded that it's a pretty-looking fabric but chintzy construction. For all these reasons, we found this item a poor value for money and returned it.
