Disneyworld - all I can say is you're tempting fate! My feet NEVER hurt until a few years ago (well, maybe after a full day of running around the parks they'd be tired). Then I got plantar fascitis (sp) and heel spurs like so many other people on these boards (this thread in particular) and so many people I talk to. Most of us are just looking for anything that helps us to not be in pain (and to avoid surgery if possible). Instead of putting others down, maybe you should be more grateful that your feet DON'T hurt. If mine didn't, I probably wouldn't have read this thread in the first place!
I don't see Crocs as the "be all, end all" that others do, but so far they've been comfortable and a nice alternative to sandals. I don't think I could wear them all day at Disney like others have, but I've never had a pair of sandals of any type (yes I've tried Tevas and Columbia and many others) that I could. But they are SO light and airy, that they seem great to relax in when getting out of regular shoes, tennis shoes, etc. at the end of the day. Plus good for just throwing on for errands, soccer games, and great for walking at water parks.
I also think they'll be great for camping this summer. I just got my husband and 2 older boys (11 and 13) a pair on Saturday (our local store didn't have small enough sizes for my 9 year old). They wore them all day yesterday and thought they were great. I really thought I'd have to convince them to wear them camping because of how dorky they looked and figured they'd NEVER wear them around home where people could see them. But they even liked them. I think they'll be good because they are so lightweight, float, rinse off so easily plus don't get sand and stuff in them (like watershoes) but since they have the closed toe (unlike sandals), they can also wear them biking (I don't let them bike in sandals). Plus they make good shower shoes. I just ordered a pair for my youngest so he'll have them before we camp the first time too!
As far as them being ugly, I think it's really a "beauty is in the eye of the beholder" thing. The more people see them (and they're definitely becoming more popular even here in Michigan), the more they'll get used to them and the better they look. I no longer think they look ugly, and as I mentioned, really don't care as long as they're comfortable!
