I like these - they fit well.  They're made of a strong elastic fabric with leather.  They aren't loose and sloppy, but they aren't too tight either - just about perfect self-adjustment, and I have narrow heels and normal-to-almost wide feet.  The soles are soft enough to be comfortable, almost like going barefoot; however, I'd be happier if they had a better arch.  The price was very good - similar sandals cost at least twice as much!
