These things are so comfortable and warm. I sleep with them on because I like to have my feet out of the covers. Not too warm...just right. Great quality and fit with a non-slip leather-like sole. I'll keep ordering these ahead of time to make sure I'll always have a fresh pair when I wear them out. I wear them EVERY NIGHT and keep them on all morning. Life-changer! The BEST EVER!!
