Shoes ........................................

Answer 2

The answer to the riddle "What is full at night and empty all day" is typically "a glove." A glove is full when you wear it at night because it fits your hand, but it's empty during the day when you take it off. This riddle plays on the idea that the glove is full when it's on your hand but empty when it's not being worn.
