Posting for my dh here!! After making fun of dd and my Crocs, he, in secret, went out and tried some on. He came home with a pair!!! Now, he owns several pair. He loves them for just kicking around in, as well as in the parks. In fact, we have some older friends, in their 70's. The dh went out and bought some Crocs because my dh raved about them. Now he is a convert as well.
I have high arches. My back can start aching, as well as my knees, if I don't get enough support. I have found the Crocs do a pretty decent job. In fact, they are really better than my New Balance or Nike 'sneakers'. Not sure why, but they are. But, they aren't for everyone. While visiting my mother-in-law last summer, we were getting ready to go out to dinner. Nothing fancy...pub type spot. When she saw what we all had on our feet (our Crocs!!) she asked if we were really going out in public in those ugly things. Ah yeah....of course we are!!!
