Numbers on the tongue of lv shoes

The tongue of LV shoes is usually marked with numbers, which may represent the size of shoes (European size and British size) and production batch.

Specifically, "408" and "#54" may indicate that the shoes were made according to the LV box-making process of 1968 (namely "40"), while "#54" may indicate the production batch of shoes.
