They are size 40. I have attached a size chart from the company. These are so comfortable if you are on your feet all day long, like a waitress or doctor/nurse, or if you are going out to a long all-day concert and you don't want your feet to hurt. These are fabulous! I have included a lot of pictures. If you have any questions, please feel free to ask before purchasing them. These comes from a smoke-free, bug-free environment. We do own a small dog.Thank you for shopping my closet! I appreciate it!
