I wear size 6.5/7 shoes (depending on whether I'm wearing heels or flats). I got these shoes in the M size and they fit perfectly. If you have slightly bigger feet, they will probably still fit, but you may need to punch another hole in the strap. The ice cream decorations are removable. One of them detached from its pin the first time I wore them, but I hot glued it back on and it's been fine ever since. These are excellent shoes and I try to find an excuse to wear them whenever I can!
