This is a quality product, but is supposed to fit men's shoe sizes 8-13. It does not even come close. I'm a size 12, and there is NO WAY that they would even come close to fitting me. I gave them to my wife who wears a size 8 women's shoe and they just barely fit her. She really likes them as they are a nice product. This is the third type of clothing item (shirt, lounge pants, and now slipper socks) that I have purchased from TANGA and NONE of them have even come close to the size that they advertise. I thought that surely the socks would be okay and fit, but I didn't realize how dedicated to sending much to small/sized clothing TANGA was. It was the last time that I will buy any type of clothing on this site. That said, if you buy these socks they really are a very nice item, just as long as your feet are small enough to fit into them.
