I noticed the medallion rubbing right away, bad idea sewing a seal to the shoe! Very uncomfortable. I ordered and received my usual size, but they are a little snug. Not sure if they're supposed to be due to stretching?? I have ordered a couple of other styles from Fly London that also went back, the flat sandal was nothing special and not very comfy. The other shoe was like this one with more straps, very comfy except I could feel the straps on the sides UNDER my feet...where sewn in, I guess. Not great.
