I have foot problems too, and I hear those crocs are very comfortable. I'm afraid to get a pair because if they ARE really comfy, I might be tempted to wear them all the time, even out in public!!
While we're on the subject, I may be in the minority, but I can't stand the whole trend of wearing beach flip flops in the city. I know every single person does it, but I think it's ridiculous. Talk about having problems later on in life! Those are practically not shoes at all! Rant over. My friends even wear them.
