I've worn mine for a week straight and most of that week was either raining, sleeting, or snowing. We waded several creeks and in many places were walking thru water running down the trail. I can't say I had any issue with them. Most every trip with take I will get in any creek or river and fart around a little while just to see if any leaks occur. Never found one yet. After close to 30 years and as many miles as I've put on them, I can say they have been punished and keep on ticking.

I will say I do like the Breeze boots for a quick drying boot.
