These won't be really tested until cold weather arrives but I found them to be comfortable and a good fit for my women's size 12 foot even tho I ordered size 11.5. I anticipate they will be good for wearing around the house on cold weather days.  The price was excellent andI think they'll do a better job of keeping my feet warm and comfortable than some similarly priced ones I have bought that don't have real sheepskin lining.  I was apprehensive about the fit but they went on with just a little coaxing and I should even be able to use a sock if necessary after they've been worn a bit to stretch them out a tad.  I think I'll probably order them in other colors too because at this price, they are a good buy and will help keep the heating bills down.
