Okay, science may never explain the shoe thing. But scroll through these lists, and the array of triggers is largely consistent: classical music, haircuts, movie trailers, Bob Ross, more Bob Ross, lots of Bob Ross, the painter best known for his popular instructional videos.

ASMR is usually precipitated by stimuli referred to as 'triggers'. ASMR triggers, which are most commonly auditory and visual, may be encountered through the interpersonal interactions of daily life. Additionally, ASMR is often triggered by exposure to specific audio and video. Such media may be specially made with the specific purpose of triggering ASMR or originally created for other purposes and later discovered to be effective as a trigger of the experience.
