Abstract: An upper for an article of footwear may include a first area located on at least one of a lateral and a medial side of the upper and a second area located adjacent to the first area. The first area may include first knit courses, at least a majority of which are at least partially formed by a first yarn, and the second area may include a plurality of second knit courses, at least a majority of which are formed by a second yarn. In some aspects, the second area includes one or more knit anchors. In some aspects, a third yarn extends from a biteline to an edge between the first area and the second area. In some aspects, a third yarn is included in the first area and has one or more of an interloped portion and a floating portion in the first area.

Abstract: An upper for an article of footwear may include a first area and a second area. The first area may be located on at least one of a lateral and a medial side of the upper, where the first area includes a plurality of first knit courses, and at least a majority of the first knit courses are at least partially formed by a first yarn. The second area may be located adjacent to the first area, where the second area extends through at least one of a lateral side and a medial side of a throat area of the upper. The second area may include a plurality of second knit courses and at least a majority of the second knit courses are formed by a second yarn. The second yarn may have a tenacity of at least 5 g/D. The first yarn may have a tenacity of less than 5 g/D, in some embodiments.
