Thumbnail dép thể thao nữ đế êm

Create a complete vertical 9:16 promotional footwear thumbnail/poster, not a plain single image. Use [ảnh người mẫu] as the exact female model reference and [ảnh sản phẩm] as the exact sporty slip-on sandal or casual slide reference. Design a realistic Vietnamese social media poster showing the female model wearing the exact footwear in a casual active pose. Include a main hero image, a cushioning-detail close-up, outsole texture panel, comfort callouts, and 3 small preview frames showing walking use, side view, and easy styling. Add a bold Vietnamese headline and a short subheadline. Keep it clear, commercial, realistic, and product-focused. No watermark.
