These initially felt fantastic!  I was a little disappointed that they didn't look like I thought they would with my jeans.  I wore them a bit and noticed that they were very hot.  I didn't have heavy socks on , but these have a bit of a thick lining or something.  After awhile I could not wait to take them off... they were miserable.  Returned them and don't regret it.  Even if I lived in a cold climate the warmth would not make up for the fact that they were just  not comfortable or cute at all!
