Use only in a freezer at -25°C, in a clean, level area (refrigeration chamber with food). You don't feel any cold at all during two hours of continuous use, nor any moisture. Perfect and lightweight. I don't know if they are waterproof, they haven't been worn outside the fridge.

I see all the comments and I can only say that mine turned out to be rubbish. They would leak with the slightest touch of water and within two months they ripped apart. I tried to put them on and they fell apart in my hand

I use them for Delivery and I have also worn the Army Race boots (same size as the shoe).
I bought them for cold days. Tested them at -1 degrees with thermal socks and didn't feel any cold. I didn't buy them for rain and they are not 100% waterproof, however in a light rain they don't let water in. I also have gaiters in the store, so even if it starts raining on the way, you can still deliver and reach the store to put on the gaiters or rain boots.
5/5 from me!

The shoe is awesome, at first glance you understand its quality and that it's worth its money. I go fishing for many hours and they have served me well, keeping my feet warm and dry. Thank you very much, I would buy them again

Initially, as soon as I received the shoes, their quality was evident even before wearing them! My husband enjoyed them at work as he works 8 hours in outdoor tasks with water and cold, of course! They are worth their money!

These boots were purchased during a period of snowfall where it was impossible for a person to go out on the street with regular shoes. My husband is very satisfied, they have good insulation and keep the foot warm in the cold. I recommend them. It's good to have them because you never know if and how much it will snow in winter.

I received the product today and I haven't tried it yet. It seems quite good quality, but I don't know if it's actually waterproof or not. The only negative thing so far is that even though they advertise it as a Canadian boot, it seems to be made in Bosnia. Also, the company refuses to provide any information about the product and refers you to where you purchased it. The 2 stars are for the company's customer service.

Update 7/1/2020: They are indeed waterproof, tested in extreme weather conditions during delivery. The only downside is that the sock appears to be wet in some areas without any water entering the boot, probably due to foot moisture. In the early morning with 4 degrees, I felt a little cold in my feet, but it's nothing compared to the rubber boots I used before. Upgrading to 4 stars for the boot.

My husband has put these to the test. They work in refrigerators at -30 degrees and finally he doesn't feel cold on his feet. Nothing penetrates them!
