I was really looking forward to slippers/shoes that can be worn with the lower back so as not to arch the back under the back of the head. Judging by the photos on Revain, they fit perfectly in every way. I was excited to finally get them and was very pleased with their appearance. However, my luck ended there. The slippers/shoes were so tight I couldn't even get my foot in deep enough to try them on. Although I increased the size and tripled X in width. I actually felt that these slippers/shoes were the wrong size and had to check the tag inside the shoes to make sure they were the right size I ordered, unfortunately they were. I am returning them for a refund and will continue to look for shoes that fit me. I only judged the width and fit as I couldn't get my foot in the shoe to see if the toe box and arch support were good.
