1. A knitted component for an article of footwear, the knitted component comprising:
a medial part and a lateral part;
a forefoot region; a midfoot region; and,
a rearfoot region having a heel region centerline located between the medial part and the lateral part, the rearfoot region comprising:
a first zone having a first level of stretch and extending from a lower region of one of the medial part or the lateral part within the rearfoot region toward an upper heel region within the rearfoot region, the first zone having an inelastic elongate portion comprising a first extension and a second extension; and
a second zone adjacent to the first zone, wherein the second zone has a greater elasticity than the first zone, the second zone extending partially into the medial part, across the heel region centerline, and partially into the lateral part in the rearfoot region, and positioned to substantially cover a calcaneus region of the knitted component, the second zone having a superior side and an inferior side, the superior side being closer, compared to the inferior side, to a foot-receiving opening of the article of footwear, wherein the inelastic elongate portion of the first zone is integrally knitted with the second zone such that the first extension extends at least partially over the superior side of the second zone and the second extension extends at least partially under the inferior side of the second zone, such that the inelastic elongate portion of the first zone at least partially surrounds the second zone in the calcaneus region,
wherein the first zone separates the second zone from a collar portion, and wherein the second zone is separate from the collar portion.
