These are fold up slippers with a storage bag. They have two plastic disks on the sole which adds stability and is nonskid. They have a soft terry cloth lining and I like the fact that they are machine washable. They are perfect for my needs as a travel slipper. I would not want to wear them for everyday as I doubt they would last long. I wear a 7 or 7 1/2 and I have a narrow foot. Some reviewers said they ran small I agonized over the size and decided to order the medium due to my narrow foot. Big mistake. My toe went right to the end so I am returning them and ordered a size up. They are a bit pricey due to the material used but otherwise they were just what I was looking for.
