I just got these boots in the pewter blue coral color, and they are so comfortable and cute! The tag says they are good down to -25 degrees so we will see this winter. In Minneapolis it can get very cold and I am hoping these will help when I am out shoveling the driveway early in the morning. I will also see if the suede is as waterproof as they say on these boots. There's nothing worse than cold and wet feet. I got a size up because I read other reviews that said Columbia boots run small. I'm glad I did, my regular size would have been too small to wear these boots with thick socks. They also have lug soles to help with traction on ice, another essential here in Minnesota. The higher shaft up the calf is nice too, to keep snow out of the boot. The other boots I had were too short and filled up with snow. The fur around the top is a nice touch. They are easy to pull on and off, and I have a high arch so I wondered about that. I am hoping for great things from these boots this winter!
