A sailing ship arrives to the port. The crew went ashore to buy new shoes. The captain purchased a pair of black shoes that were size 46. The lookout purchased a pair of brown shoes of size 47. What kind of shoes did the stoker purchase?

I honestly have no idea what size thing do you use for shoes.
I honestly can't come up with a clever signature.
