商品紹介：スニーカーの構造を見せる

An original, polished commercial visual for a fictional unbranded product. 8-second continuous video, coherent object geometry and physically believable motion, rich studio lighting, crisp professional detail. No brand logos, no lettering, no captions, no watermark. Silent. A single original white and yellow athletic sneaker floats against a pale gray studio background. It rotates slowly, then smoothly separates into exactly three aligned layers: upper, insole, and outsole. The three layers hover briefly with clear spacing and then assemble precisely into the original shoe. Camera remains stable, elegant soft shadows, no feet or people, no logos.
