Here are some examples of waterproof casual shoes/boots at REI:

For some reason they do not list the Merrill Jungle Moc as “waterproof”; they say it is water-resistant.

But the Merrell website says they are waterproof ( and asks a higher price):

Maybe the one REI is selling is a different model, but it looks exactly the same and has the same name. All I know is that I have had a pair of these in the “gum smoke” color for 4-5 years, use them as my main walking shoe (when we are not actually hiking on rugged trails), and they have kept my feet warm and dry in our wet climate, even when I walk through puddles or even into the lake at the shore to retrieve a tennis ball the dog drops there instead of bringing it right to me. As long as the water does not go over the tops, my feet stay dry for the brief dip. I wouldn’t plan on standing in the lake or puddle for extended periods.
They are also very comfortable and supporting for walks of 5 miles on pavement ( did a lot of that last year). Maybe it is just that Merrells fit my feet really well, but REI does not have my size.
Do pay attention to Carol’s recommendation for Smartwool (or other merino wool) socks. They are great for blister-avoidance and general comfort, even if your feet do get wet. We had to walk through a thigh-deep flooded area while hiking the Milford Track in New Zealand, and then hike another 10 miles more (after we emptied the water out of our boots and “wrung out” our socks. No issues at all with cold feet or blisters. I was already a believer in merino socks, but that was an unexpected benefit.
Now all I wear is merino socks (Smartwool, Icebreaker, Darn Tough, Bombas, or Farm to Feet). Smartwool even makes “no show” footie sox for sneakers—and they don’t slip down. You can usually find something on sale if you look around . . .
