An article, comprising: a first reflowed material (712); and a second element (708) selected from a second shaped component, a second film, a second textile, a second yarn, or a second fiber. The first reflowed material (712) is a melted and re-solidified product of a first element selected from a first shaped component, a first film, a first yarn, a first fiber, a first textile, or any combination thereof. The second element is a dyed second element, whereas the first reflowed material is substantially free of the dye (716). Also related articles and methods.

技术问题语段：

The traditional method of making certain articles of wear, like footwear, involves cutting individual pieces of material and combining them using sewing or adhesives. This process is wasteful, labor-intensive, and prone to errors, which leads to increased waste and manufacturing time and energy. The technical problem addressed in this patent is finding a way to make these articles without the need for multiple pieces of material that have to be combined.

技术功效语段：

The present invention relates to articles of apparel, footwear, and sporting equipment made by combining materials with low processing temperature polymeric compositions and high processing temperature polymeric compositions. This lowers waste, labor, and errors in the manufacturing process. The invention also provides methods for making these articles using these materials. The technical effects of the invention include improved efficiency in manufacturing, reduced labor and material waste, and improved performance and comfort of the article.
