I've been wearing them constantly, including all day at a museum, and they are wonderful. But it's still cold and I was wearing them with socks (black mary janes and black socks with slacks on). They are much less offensive looking, that's for sure. I don't even notice the strap, and they are more narrow so I don't feel like I'm as clumsy on my feet as I do in regular Crocs.
I'm not sure if I'll like my lavender ones as much in the summer with no socks, but we'll see.
Edit: Ooops, just noticed I mistakenly posted on this old thread. Meant to post on a newer one...
