球鞋发售倒计时故事

Vertical 9:16 hype-drop sneaker ad frame. A single floating low-top sneaker in vibrant electric blue mesh upper with a chunky white midsole, lit from a single hard top-right key light against a pure matte black background. A thin neon orange digital countdown timer overlay at the top reads "03 : 12 : 47" and the smaller word "DROPS FRIDAY" sits beneath. Subtle motion blur particles around the shoe. No brand logo on the shoe, no swoosh, no watermark. Premium streetwear product ad design, photorealistic shoe materials, ultra sharp focus.
