Very comfy and warm boots. Not heavy at all compared to other boots of equal insulation quality.
I've used mine the entire winter season (5 months where I live) for 4 years to normal daily walking, but also snow shoeing and longer walks, and they are still warm and comfy. But the rubber around the lower part is now beginning to crack, and they will not last a new season (unless duck tape is used).
But I am so fond of them, that I'am now ordering a new identical pair :)
