This slide runs a bit narrow (I do have mild flat feet). For me they are effectively over-ear, but they become uncomfortable after about half an hour. Confortable, lovely, I have taken a Large size and I?m 9. These are so comfy and despite several compliments, no one has yet realised they?re crocs! Less padding around the opening and dont expect to use all the holes the laces go in because the laces are a few inches too short. At first when I looked at the stereo it was half the size of stereo decks that Ive installed in years past amazing how technology is able to cram everything down into a smaller unit and still perform really well. I just rinse out the cloth and use that to wipe off the suds. I order my same size and when I received them, they are about 3 sizes too small! These are not at all cute like they look in picture. They look like months old.
