I did quite a bit of online research to find a pair of comfortable, stylish, and waterproof boat shoes.  I am so happy I found these. I walked long distance on these and they provide excellent support.  I haven't tried the waterproof feature yet.  Note that there are mesh sidings on these shoes, so they will not keep your feet dry when water comes.  But at least water will not cause damage to the shoes if the waterproof feature holds true.
