Perfect lightweight warm boot except after two months regular wear, both boots developed a loud annoying squeak.
Otherwise, awesome sole good for multiple ankle/foot articulations, not at all stiff. Warm for 30-60 minute hikes with dog in Wisconsin winter, even at -30 F (shorter hike that day :o)
Warm, lightweight and noisy.

Thought I posted this review earlier, but it didn't show up, so if this is 2X...
Warm in coldest WI weather for 30-60 minutes hikes with dog in deep snow and snowdrifts. However, both boots developed loud squeak after two months regular wear. Otherwise, the perfect boot.

Light and warm!

Definitely warm and protective. Tromped through inches of Chicago snow and slush without feeling a thing. My only problem is the right show squeaks when I walk--it feels like there is a crack or something in the sole. This started maybe a week after getting them, so it's not from too much use.

These boots are light and feel great on your feet but they are NOT warm in the area where it's rubber. Where the fabric ends, so does the warmth! I was out in 39 degree weather, had on wool socks and my toes got icy cold. It says good to 25 below.... trust me, they're not! I called the company and they just shrugged me off.... well you're the only caller. I couldn't believe it. I expected much more from Columbia. They 'had' a good reputation until now in my book.

I live in Jackson Hole, Wy. It gets plenty cold here, and these boots have kept me warm enough. Their performance on ice, however, not so good. So I would say these boots are great for tromping through the snow, but watch out if you come upon any ice.

I purchased these boots because I have a puppy that needs to go outside very often. We've had 12 inches of snow in the past 24 hours, with temperatures as low as 8 degrees. They have kept my feet dry & warm. They are also high enough to keep the snow from getting inside. Best boots I've had in years!
