I did check those out and they are nice (with a capital $ - whats up with that?). Did not try them on though. However I like the fact that the Tevas have the adjustable heel strap. Lets you position your foot on the footbed relative to the arch, front & rear overhang, etc.

I do know some Chaco owners/wearers and they truly do live in those things. They must have a secret handshake or something - much more apt to strike up a conversation with a total stranger over their Chacos than any other brand of shoe wearers I've seen.
