Marc,
I don't think there is any miracle topical dressing that is 100% waterproof....so, here's the real deal IMO....
Danner Boots are top shelf leather, waterproofed and lined with Gor Tex and available in all styles, Vibram soles and so forth. Not cheap, but with the waterproof Gor Tex you can stand in the creek for as long as you like.
Danner uses 3M Thinsulate Insulation, the warmest thinnest insulation on the market. If you Mink Oil these boots annually or more often they will last years and years.
Danner has been making boots since 1932 and Danner has been using Gore Tex since 1979 when W.L. Gore invented the stuff.
Made entirely in the U.S.A., in Portland, Oregon.
Regards,
