Lost JoJo In The Snow Boot

HOw do you loose a little boot like this especially as the brand is called JoJo in the Snow?  Saw this sitting on a wall out the front of a property close to an infants school, so I am hoping that the owner found it.  Kid's clothing is so expensive and when you misplace part of a set, I bet is it so upsetting for the little owner, not to mention the parents.
