About 1 year ago I purchased a pair off Sand color midcalf original Australian Ugg boots. They are made of sheep skin and fur in the inside and I wear them all the time! I love in the Northeast and they are extremely cozy and warm in the dead of winter and I don't even need to wear socks! The only downside is that you have to be careful in wet weather as the material can get stained and the fur on the inside has become matted down since I wear them so much! I paid $120 for them and although I realize that is very expensive, it was well worth it because my feet are always cozy and comfy. I will definitely purchase another pair once I completely wear these out but I will probably buy the Chestnut colored ones the next time because my sand colored pair tend to get dirty easily.
