I think the Vibram Five Fingers helped the downfall too. I bought a pair of the KSOs and there's been two days I haven't worn them since I got them. People that buy crocs want to have neat shoes that are a little eccentric. They stop being eccentric when everyone has them. Vibrams are now more eccentric than crocs, so the fad is fading. This isn't to say that crocs won't continue to have regular customers though.
