shoe-check token; number tag for deposited shoes
A numbered token given when leaving shoes at the entrance of a public bath, traditional restaurant, or similar establishment. The token is used to retrieve the shoes later.
I received a shoe-check token at the public bath and left my shoes.
Compound of 下足 (げそく, 'removed footwear') and 札 (ふだ, 'tag' or 'token'). The exact historical derivation is uncertain, but the word is transparently formed from its components.
