Chaco flips are THE best made at any price.  Extremely comfortable, awesome arch, no-nonsense upper that doesn't get in the way and looks good too.  This is my fourth pair in about eight years; I wear them every day (this is my dress shoe, I have cheap Reefs I use at the beach).  Once perhaps seven years ago, I walked 15 miles in these things (honestly, long story).  Best made, period.
