These boots are bottom line: amazing. Super comfy and warm. Zipper all the way down the inside of each boot. Good traction, but no flex in the sole. Super comfy, super warm. I chose these because I have large calves and the laces help if i need to loosen them. I wish I could wear them to bed! I would pay twice as much for these boots. I have owned many pairs of boots and none compare to these. GET THEM.
