The term "style code", "ID" or "SKU" refers to a unique identifier assigned to a specific sneaker model by the manufacturer. This code can be used to identify the brand, model, colorway, and other information about the shoe. It is often used by sneaker enthusiasts and retailers to accurately identify and track a certain model of shoe. It is commonly found on the shoe's packaging or on the shoe's tag, and can also be found by searching for the style code on the manufacturer's website.
