We actually bought some of those shoe-ins. I'm surprised at the positive reviews. In my experience they are designed with street shoes in mind and even the XL didn't fit comfortably over my size-12 wading shoes.

Really I'm looking for dirt cheap wading shoes that I can get in a couple sizes to say "wear these instead," which is why the Cabelas shoes are so appealing. Cabelas doesn't make any of their own stuff and I'm sure those shoes started off life as flats boots from some standard MFG, but it sure sounds like only Cabelas got them modified with felt soles. I'm strongly inclined to go with felt soles rather than some material with less traction, because invariably somebody will fall if we give them something to wear getting in and out of the boat and numerous lawyers have informed us that our insurance waiver is meaningless if somebody actually gets hurt...
