About this product

“Must Be The Denim” is the colourway name on this men’s Nike Book 2, but it does not specify which colours appear on the shoe or where they sit. The name evokes denim’s familiar visual language without establishing that denim is used as a material. Released in 2026, this Book 2 also features Air Zoom. Those details give the pair its identity without assigning it an unsupported shade or finish.
