Cinematic Sneaker Ad Poster Prompt

A cinematic vertical sneaker advertisement poster (9:16 ratio). A young American white man with sharp jawline and defined facial features, wearing a black hoodie and joggers, caught in a powerful forward lunge - one knee bent deep, fist driving forward, shot from below. Massive bold typography "IGNITE" in fiery red bleeds through the background. Brand name "BLAZE" at the bottom with taglines: "PUSH HARDER." / "BURN BRIGHTER." / "NO LIMITS." Sleek black and red sneakers dominate the lower foreground. Dark charcoal to warm ember gradient background with smoke and ember particles. Ultra photorealistic, 8K, no text overlays on subject, cinematic color grading.
