Converting simple present active to passive: object (blue shoes) becomes subject + are + past participle (worn) + agent (by them). Since “shoes” is plural, “are” is correct. Simple present passive describes a habitual action or general fact—wearing blue shoes as a regular practice. This transformation emphasizes the shoes themselves rather than the wearers, useful in descriptions of clothing, customs, or typical behaviors.
