guys - FYI - just got off the phone with Cabelas and they said their boots are designed to accomodate the neopreme foot of a stockingfoot wader, so you should order normal size.
I have some Cabelas wading boots and they're great, the backcountry model that sell for $60 I believe. I generally wear an 11.5 shoe so I got the 12 and they fit perfectly.
