An article of footwear with a knitted component including an upper and an integral knit ankle cuff is provided. The upper and the ankle cuff are formed as a one-piece knit element. The knit element forms a portion of an exterior surface of the upper and an opposite interior surface of the upper, with the interior surface forming a void for receiving a foot. The ankle cuff is formed of unitary knit construction with the upper as a one-piece knit element and extends above a throat area of the upper. The ankle cuff includes malleolus zones on medial and lateral sides to correspond with the ankle bones of a wearer. The knit component further incorporates features to assist with providing entry for a foot of a wear, providing comfort to a wearer, and to assist with orientation of the upper of the article of footwear when being worn.
