These are definitely several steps above your average flip flop.  Or your fancy flip flop.  I live in Florida - we are flip flop experts. And these Tevas have been my staple footwear for more than a decade.

I can wear these to walk long distances (don't tell the podiatrist) with no rubbing or discomfort.  They have good arch support (!) and the sandal design means there is neither too much flipping nor flopping going on.  I always have a pair going and a spare on the closet shelf.  I live in fear of discontinuation.

The uppers never wear out, but when I have worn the tread off the bottom (takes a year or two) I have a tendency to go sliding and fall in wet summer weather, so I break out a new pair.  I'm sure I could find a way to rough up the sole again - but I like a new color periodically!
