I haven't had a chance to try them in the rain yet. When I got the first pair, the left boot was significantly narrower than the right and was causing me a lot of pain. The right one fit well, but I had to use a shoe stretcher to get the left one pain free; now everything is in order. I've ordered a second pair a half size bigger and wider and both are fine. I'll have to see how it all goes after wearing them for about a year.
