I was so excited to receive my order and then a little disappointed too.  The quality of the product is outstanding!  Very sturdy soles, well made overall and they are very warm!  However, the description said there would be good arch support and in my opinion, there is very little. That's the only reason I didn't give it a 5-star rating.  Arch support is one of the main features I want & need and I have yet to find a slipper that has it.  Granted, most slippers are flat & flimsy so in comparison these far exceed that type.  For the price, I was hoping I had found what I was looking for but sadly I will keep looking--next year.  I know some reviewers had a problem with the sizing but I found it to be exactly right for me.
