I was not happy with these slippers at all....I have hard wood floors, so I need to wear something on my fee all the time...When I started to wear them, my foot was moving and the friction of the material was burning my feet.  It wasn't because they were the wrong size, it was the fabric.  This product may work for others, but it did not for me.  I was very disappointed, it was a lot of money to spend on slippers....that didn't do what I needed.
