I bought these for my sister who is always cold.  We live in Florida.  I know these DO NOT compare to the quality of Uggs, but they are pretty nice for the $25 I paid. These will not be worn in real winter weather so they are actually perfect for our winters. They aren't bulky and slip on easily.  They run big. My sister wears a 6/6.5 and the size 5 fits. I wear a 7/8 and I can even get them on.  They are very comfortable.  In states that have real winters these would make great indoor slippers.
FYI...I am a total shoe "snob".  I have a closet full of Gucci, Chanel, Prada and more.
