I purchased these slippers for my husband who has had foot surgery and required the most comfortable and adjustable shoes/slippers I could find. He normally takes a size large, but I ordered an extra large to allow for swelling, etc. Unfortunately, these slippers do not run accurate to size as the slippers would not even go onto the foot which was not swollen! I have returned them to the seller as directed on the packaging but have not heard back and do not have evidence of a refund after 2 weeks. Poor communication from seller and inaccurate sizing equals a very poor rating!
