In one aspect, an upper for an article of footwear may include a knit element, a collar area configured to form an ankle opening, and a cuff in the collar area. The cuff may be at least partially formed by the knit element and may include a ribbed knit structure of the knit element. In another aspect, an upper for an article of footwear may include a knit element with a first area, the first area including a first side and a second side opposite the first side. The first side may be formed of at least 30% more material than the second side such that the first area is configured to curve convexly away from the first side.

The present invention provides a method for knitting three-dimensional shoe blanks, comprising: knitting a heel and lateral portion; continuing knitting a rear sole portion; continuing knitting a front sole portion; continuing knitting a toe cap portion; and continuing knitting a tongue portion. When the knitting comes to the first connecting selvage edges at the two sides of the rear sole portion, the first connecting selvage edges can be knitted together with the lateral live stitches in the heel and lateral portion, so that the heel and lateral portion can be combined with the rear sole portion. Also, when the knitting comes to the second connecting selvage edges at the two sides of the toe cap portion, the second connecting selvage edges can be knitted together with the latitudinal live stitches in the front sole portion, so that the toe cap portion can be combined with the front sole portion.

An upper for a shoe and a shoe including an upper and a sole that is connected to the upper may be provided. In one implementation, an upper for a shoe may be provided, the shoe including the upper and a sole connected to a lower edge of the upper via injection molding. The upper may include a first knitted area having a first stitch density, wherein a portion of the first knitted area may be located at the lower edge of the upper and may include a first meltable material having a first melting temperature. The first meltable material may be melted prior to or during the connection of the sole to the upper and may limit the flow of molding material through a melted area of the upper.

A method for forming an article of footwear includes forming a knitted component. The knitted component may include a first knitted portion and a second knitted portion, where the first knitted portion at least partially forms at least one of a medial side, a lateral side, and a toe area of the upper, and where the second knitted portion forms a tongue area of the upper. The second knitted portion may include a first end and a second end where one of the first end is secured to the first knitted portion via a common knit structure.

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.

An upper for an article of footwear may have a knitted component, where the knitted component has a first edge extending from a first side of a throat area of the upper, through a heel area of the upper, and to a second side of the throat area. At least a portion of the first edge may include a lattice structure, the lattice structuring having a first lattice band and a second lattice band, the first lattice band and the second lattice band having loops that are intermeshed in at least one location, where a plurality of first openings are located between the first lattice band and the second lattice band. At least one of the lattice bands may include a yarn having a tenacity of at least 5 g/d, and/or the first and second lattice bands may be formed from separate yarns.

Aspects herein are directed to a sock having an integrally knit, two-layered tab positioned interior to a collar of the sock, where the collar defines an opening for a wearer's foot. By positioning the tab interior to the collar, the tab can be used to assist the wearer in donning and/or doffing the sock by acting as the primary structure by which the wearer pulls an elastic collar around the wearer's foot when donning the sock.

Aspects herein are directed to a knit sock having a leg portion and an integrally knit ankle welt extending around a circumference of the leg portion and positioned at a lower end of the leg portion. The knit sock further includes an integrally knit tab located at a back aspect of the ankle welt.
