I've been doing a little research on this type of boot. For more of a budget boot, Rocky Outbacks seem to have a pretty solid following. Most reviewers only complaints are that they run small.
I suppose it is possible. I see pretty much all moc toe upland boots have exposed stitching, though. They do often add a piece of "shark skin" to the tip of the toe, but leave the stitching exposed. Weird.
I seem seal all my boots and have used tough on work boots it helps how much I can't say. Dont think I would have to seem seal my boots but the old days of bread sacks keeping my feet dry having me take every precaution I can.
