I am very critical of shoes, all shoes, including slippers. I have ugg slippers that I really like. However, I love this one. I really appreciate that they are made from natural fibers and materials, with no plastic or chemical ingredients. They are very comfortable and keep my feet warm without getting too hot or sweaty. I actually wore them to bed and they didn't bother me all night. I'm also pleased with the lack of arch support as they force me to hold my arch up like I do yoga which improves my overall posture. I will be ordering more for myself and for gifts.
