5 size down and now fits perfect. See last photo. The bass is excellently controlled in its delivery. This keeps my ears warm and its not too tight. My skin was itchy all over & when I perspired, I would get itchy red bumps. I bought a hot pink pair. The sound quality is great and all, but sometimes I just want to blow up my ear drums and listen to music very loud and fall completely into the sound. Ive been wearing these shoes for 2 weeks thinking maybe they will stretch a bit but so far they havent and are the most uncomfortable shoes Ive ever worn. It has a sheer back and mid section so make sure to get either a clear bra or the cups. There is a stiff edge at back of slipper and cuts into my heal.
