An article of footwear may incorporate various elements that are at least partially formed through a knitting process, such as a circular knitting process or a flat knitting process. Examples of the elements include tongue elements, collar elements, and collar-throat elements. In some configurations, the elements include compressible areas and flange areas. The compressible areas may include foam cores or floating yarns that impart compressibility, and the flange areas may be utilized to join the components to the article of footwear.
