These are super cute and comfy.  I live in MN and I wear nothing but boots from Nov to March.  I wear these all day, approximately 4-5 times a week.  They are warm, cute, and have no quality issues after being worn 100 times.  I drag my heels, and these do not even show signs of wear on the heels like many of my well-worn shoes do.  I also think the linings are high quality, and I actually prefer the wool in the shaft and the sheepskin in the footbed.  It makes it comfortable and super warm.  I also own Ugg/Bearpaw boots and find these to be an equivalent quality to Uggs.  I think these will last several winters for me, even with frequent wear.
