The Ultraboost DNA “Grey Black” IG6003 adapts adidas’ famous Ultraboost running design for everyday wear, pairing a flexible knit upper that hugs the foot like a sock with a moulded TPU side cage and iconic heel counter for structure and lockdown. The grey knit is contrasted with black details on the cage, heel and outsole, creating a clean, neutral look that works with sportswear and casual outfits. Underfoot, the shoe uses a highly responsive cushioned midsole (in the DNA family this is tuned for lifestyle comfort) and a durable rubber outsole that grips city pavements, making the model suitable for commuting, light runs and all‑day standing.
