the sizing on this product is a little big in length. if you have a low arch you may want to consider the size down. I have a high arch and the product fits in the band going over the foot but not in lenrth. it is about an inch too long in front and back of the foot. there is also a embroidered seal on the heal that rubs the bottom of the foot and rubs the bottom of the foot. but the slipper is comfortable to stand on for extended periods.
