UGG boots (Parkside SK7)

I was given these by a friend who doesn't want them back since they don't fit my daughter. They are supposed to be a 3 i believe but my daughter couldn't even get her foot in them not sure if they are faulty or just extremely narrow. Collection tomorrow ideally I can leave them in the parcel box outside for collection anytime as long as I know your coming in advance of me going out.
