The shower shoes from AAFES were too flimsy, the Nike sandals I bought absorbed water in the last and soon smelled funky.  Crocs to the rescue!  Normally I wouldn't wear Crocs, because they look horrible.  These babies, on the other hand, are simply a very robust flip flop with very little that could potentailly be absorbent.  They look just fine.  And...the multi-layer footbed hasn't taken on any water as yet, nor has the leather/leatherette strap that sits between the big toe and the other toes.  They are very comfortable and the sole is robust enout for FOB gravel.  I'm a fan.  A nice deployment treat.
