"I totally agree with the previous reviewer that the inside stitching HURTS at first (really dumb design). BUT I decided to wear them for a bit and see if the stitching wears down and it totally does (and fairly quickly too). I don't notice it at all anymore. Super comfy, easy to throw on, go with everything (casual) shoes. I would recommend buying half a size down from normal. They seemed to fit me great at first, but as the fuzzy inside lays down they get bigger. I plan to buy these again (in a smaller size) when my current pair wears out."
