I have been having problems with cold feet in the winter in recent years, and wool socks just aren't enough. I put these on, however, and my feet are toasty warm. The best purchase I have made in a long time.
New to an open back kind of construction, I missed the natural grip on the back of my heel, so almost returned these for an exchange, but quickly adjusted to the style. I need a EEE shoe and have a high instep and these slippers fit just fine. I vote two bunions up. These are a keeper.
