Sizing:  So, because of my weird feet, it's always difficult to decide which size to get.  I can wear from 7 1/2 to a 9.  With the boots, I was deciding between an 8 or an 8.5.  I decided to go with the 8.5 and I don't regret it.  I probably would have been ok with an 8, but would have been harder to tuck my pants into them.

Comfort:  Very comfy.  When they arrived, they were heavier than I expected (which I was thankful for) and the fur inside is comfortable.  The whole thing is comfortable.

Warmth:  I wore the boots out today and while I don't know how warm they will feel in like single digit weather,  it was 19 degrees today, but wind made it feel like 12, but the boots kept my feet warm.

Shipping:  They arrived quickly.....like literally in a day lol to which I'm thankful for.  Overall, I definitely recommend these boots.  I'm hoping to see how they hold up in snow soon.
