I have been searching for a good pair of waterproof hiking shoes for awhile and these are perfect!  They aren't bulky in appearance and while they aren't cushy, they are very comfortable.  They are very light and relatively breathable and they really are waterproof!  I bought these right before a trip to alaska and at one point I had to cross a stream using some slippery rocks as a path.  My foot slipped a few times but my feet never got wet.
