I wanted a pair of water shoes or socks for a trip to a water park, so I took a chance on these.  These were much more expensive than the typical water socks, but turn out to be far superior as well.  You'll have no problem driving a car, walking a bit (even up steep inclines), and of course they are great in or even under water.  When wet, most of the water will drain out through the drain holes along the bottom of the shoe.  A small amount will remain in the inserts, but the inserts are comfortable enough that this isn't really an issue.  About the only negative, and it isn't serious, is that the treads on these are much bigger than I expected.  This has no effect on your use of the shoes (other than providing good traction and shock absorbtion), but I was worried that I might be asked to take off the shoes at the water park.  Fortunately no one said anything since they are clearly water shoes.  The somewhat unattractive colors actually helps here, I think, although I'm starting to like the green.  I'd definitely choose these again.  I look forward to trying them out in different situations; I think they'd make the perfect shoes for white water rafting.
