I bought these boots for a four night canoe camping trip in the Boundary Waters, recognizing that I was buying them for a purpose they are not advertised for. When canoe camping, you step in a few inches of water for a 1-10 seconds every now and then. I really thought that because of their rubber bottom and leather upper, and because they are advertised for "sloppy" winter weather they would be okay, meaning that maybe they would leak a little bit,. But I had FULL ON sloshing feet. And as they dried every night, you could see that the seams would be wet (see picture, they are still wet two days after canoe camping), meaning to me that the seaming is poor. I wish I had used mink oil on the leather before I headed out. That might have made a difference on my experience. I bought a size 8 mens, when I'm a 9-9.5 womens, and wore waterproof socks and wool socks underneath. The only reason why I didn't give these a lower rating is because they were comfortable (possibly because I had two pairs of socks on) and lightweight despite being water logged. They also handled decently on rocks while portaging on the trails between lakes, but *decently* is the key word. From my experience I doubt they would be okay in anything beyond light, low snow. I strongly doubt they would do okay in that gross, sloshy snow we can have here in the streets in Chicago winter.
