I do surveys that require me to dive into the surf. They don't completely protect from water, but I'd be honestly surprised if they did given the conditions I use them in. If I wanted to stay completely dry, I would need a dry suit or waders. They are often completely submerged and tossed about by the waves, and while the tip seal is effective, water can still get in. When that happens it actually helps keep my feet warm. I have used them both in summer and winter and they make my work easier.
