I bought two pairs of these boots at 17$ each last summer getting myself ready to face harsh and bitter Canadian Winter. To my surprise, the boots passed the test. I mean literally passed the test and withstand very well - 4 F last night in Montreal. My feet are warm from the back all the way to the tip of my toes while waiting for commuter trains and buses, although  they are not comfortable walking in due to poorly made soles. But I bought a pair of insoles to insert it in and the result is like walking on a spring-very comfortable. I highly recommend to those of you who live in a very cold place like I do. I'm 100% sure you will like the boots.
