First impression: REALLY like these! I had a pair that were a couple years old that I also really liked but these seem to have some great upgrades.
The foot area is better fitted, not snug but more fitted to the foot than the old ones which were almost too roomy. They also have a nicer look than the old ones, a little less boxy/clunky.
We'll see how they hold up and unfortunately I will have to wait until next winter to see if they are as warm as the old version.
