Create a vibrant sneaker design inspired by Soviet-style posters, blending the bold, striking aesthetics of USSR propaganda with a touch of anime flair. The design should feature high detail reminiscent of offset printing, presented as an engaging, colorful poster in an 8K resolution. Capture a happy, optimistic vibe through natural lighting, making the sneakers stand out vividly against the detailed background. Use a 2:3 aspect ratio and CMYK colors for a crisp, professional finish that honors the unique fusion of styles.
