I love these.  I tried on tons of boots and these were, by far, the most comfortable all around.  They're almost like wearing slippers.  They definitely keep your feet warm.  My feet are always the first part of me to get cold so I decided to finally spring for a nice pair of winter boots.  I picked these thinking there would be no way my feet would actually stay warm.  I was wrong. I stood outside with temps under freezing, in over 2 feet of snow for over a hour, and my toes were as warm as when the boots went on. And that was wearing cheap and thin socks.

The snow was way over the tops of the boots and nothing got wet.  The "fleece" lining captured all of the snow so my feet stayed dry.

I have claustrophobic ankles.  I hate anything that's tight around my ankles  These were perfect.  I am able to tighten them until they are comfortable.

Very rugged.

Nice and heavy.

Decent traction.

Two thumbs up.
