Namie's Boots are Made for...EVERYTHING

Why does she wear those same boots in every video? I just realized that today. My sister and I were watching my Space of Hip-Pop DVD and noticed her pretty shoes, then I went to watch the WoWa video and noticed them again. Then again in Baby Don't Cry, FUNKY TOWN. CSCEIS (twice!!), and Hide & Seek.

What's up with that? Are they like her favourite pair or something? Has anyone else noticed this weirdness?
