I wear women's US size 10 to 11 and these were a great fit, not too tight, but not so loose that they'd slide off too easily. That being said, not recommended for men with a shoe size any bigger than US men's 8.5 - 9.5. \n\nOther than that, they're very soft and comfortable and have so far been doing a great job keeping my feet warm when I go to sleep.
