These were too tight at first but I was able to stretch them because they are jelly on the straps but do not pull too much or they will pull out.  I had to put them back in but no issues with that to date.  I think they are poor quality for the MK label and the price and the michael Kors emblem on the underside will get dirty from walking and will fall off, come unglued pretty easily.  I only wore these a couple of times before they started falling apart.  Poor Quality.
