Definitely NOT waterproof.
"I have been using these boots for the winter season. Unfortunately, one very problematic issue I've had since starting to use them is that the snow sticks to the toes of the boots, and when I return inside to warmer temperatures, the snow melts, and immediately my toes are soaked because the wetness seeps through the stitching of the toes and it feels like I've walked through a cold, wet swamp. I was skeptical at first and thought maybe I had cold feet wet feet from working outside, while sweating in my boots, but I've now used these long enough to know that no, these boots simply aren't waterproof. I was very excited when I got this pair, and that excitement has very quickly snowballed into disappointment. It's sad that when you try and support Canadian, this is the quality of the product you're putting out."
