I have rheumatoid arthritis, which causes pain in my feet, ankles, knees, and hips. I also have hardwood floors! I had gotten to where I would slip my Vionic shoes or sandals on even with my pajamas to walk around the house. Well, of course this looked just ridiculous! I eventually treated myself to these and I'm pleased to say the support is just as good as the shoes. My feet and legs stay in alignment and the shock absorption is excellent.  I love the plush material.  These are living by my bedside.  FYI, I'm a 7.5 in Vionic shoes but I get a 7 in the sandals and got a 7 in these slippers - all fit well. Cheers
