are

Answer 2

No oobleck, It's where because a verb is a word used to describe an action, state, or occurrence, and forming the main part of the predicate of a sentence, such as hear, become, happen.

Answer 3

if you look up "where" in the dictionary, you will not find it listed as a verb, only an adverb.

If you consider "shoes" as the subject, the only possible verb is "are"
