I love the way my Zongs look, but in the weeks that I've had them I've never been able to make them fit quite right. They're definitely the right size, but no matter how much I pull on the various straps they still don't seem to fit the way they should. The bottoms of my feet have developed little blisters and a couple of the straps, including the toe strap as others have mentioned, seem to tighten whenever I walk very far. It's not a big deal; the sandal's still pretty comfortable and it just takes a few moments to loosen the straps again. I still wear them almost constantly. They're pretty comfortable and have much more support than any of my other sandals.
