I needed support around the house for my Plantar Fasciitis and these are great.  I usually wear a size 10.5 or 11, so ordered an 11 and they are perfect.  Other reviewers said they made their feet sweat and suggested wearing cotton socks with them.... that works great and solves the problem.  Yes, the fur gets squished quickly, but I bought them for the deep heel cup and arch support, not the fur.
