In Bolivia, on Christmas Eve, a figure known as "Tio de Nadal" or "El Tio" takes children's old shoes from their windows in exchange for new gifts. This tradition involves children placing their old shoes by the window, and during the night, the Tio de Nadal replaces them with new gifts as a way of spreading joy and festive spirit during the holiday season. This custom is a unique and heartwarming tradition in Bolivia, adding a special touch to the Christmas celebrations for children.
