Banner pubblicitario per soletta Japanese Cloud

Create a high-converting Japanese e-commerce product advertisement square image for a pair of ultra-cushioned insoles, styled like a Rakuten marketplace hero banner. Bright sky-blue gradient background with soft white clouds, clean glossy commercial design, energetic and premium. Large central Japanese headline in bold white calligraphic serif text with blue glow: "雲インソール". Above it, a rounded white capsule banner with blue text: "履いた瞬間ふわっ！". Below the main headline, smaller white handwritten-style Japanese subheading: "まるで雲の上を歩くような心地よさ". Show 4 insole product views total: 1 large white foam sole held vertically in a realistic human hand at lower left foreground, featuring a pebble-like bubble texture with small ventilation holes; 1 gray fabric-covered insole standing upright in the center; 2 stacked angled white insoles at lower right, emphasizing thick soft cushioning and textured underside. Add a large gold award badge at top left with crown and laurel, containing the Japanese text "第1位" and a red ribbon reading "楽天ランキング". Add a vertical gold ribbon badge at top right with the Japanese text "累計販売数 10万足 突破!". On the left side, place 4 vertically stacked rounded white icon boxes under a small blue handwritten caption "こんなお悩みに!", with simple blue line icons and labels: 1 "足の疲れ", 2 "衝撃吸収", 3 "長時間の立ち仕事", 4 "ウォーキング スポーツに". On the right side, place 2 rounded white feature boxes with blue outlines and blue-gray icon illustrations: top box text "衝撃吸収 疲れにくい" with a walking person icon; bottom box text "通気性◎ ムレにくい" with airflow lines icon. At the bottom right, add a large white cloud-shaped callout with bold blue Japanese text "極上の クッション感" and a tiny blue cloud icon. At the bottom center, place a small blue rounded label "選べるサイズ" with large blue size text underneath: "23.0cm〜29.0cm". Use crisp product-photography lighting, soft shadows, glossy highlights, vivid contrast, and a polished online shopping ad composition optimized for instant conversion.
