The present disclosure provides an upper for an article of footwear. The upper may include a knit element defining a portion of at least one of an exterior surface of the upper and an opposite interior surface of the upper. The interior surface may define a void. A tongue and the knit element may have a common yarn, and the tongue may extend through a throat area of the upper. The tongue may comprise a lateral edge, a medial edge, and a forward portion. At least one of the lateral edge, the medial edge, and the forward portion may be unsecured to the knit element. The tongue may be secured to the knit element at least at one of the lateral edge, the medial edge, and the forward portion of the throat area.

Computer-implemented method for determining production values for producing a custom-tailored, in particular skin-tight, knitted garment (31) for a limb (3) of a person, comprising the steps of receiving a three-dimensional dataset (11) of the limb (3) acquired using a 3D scan device (21), receiving at least one height value describing the dimension of a knitting row (9) in the lengthwise direction of the limb (3) and at least one total length value for at least one lengthwise section (4) of the garment (31) and determining a number of knitting rows (9) for the at least one section (4) of the garment (31) by dividing the total length value by the height value, evaluating the three-dimensional dataset (11) to derive a circumference information describing the circumference of the limb (3) along at least the length of the limb (3) covered by the at least one section (4), from the circumference information, determining a circumference value for each n-th knitting row (9) or each knitting row (9) except every n-th knitting row (9), wherein n is a natural number, in the at least one section (4), wherein the circumference values are used as and/or for deriving production values for the knitted garment (31).

Computer based systems and methods for designing (e.g., customization) of consumer products, articles of footwear, knit footwear uppers, and the like. In some embodiments, a user may generate and/or modify footwear designs using a footwear design interface. Additionally or alternatively, the footwear design interface may be configured to simulate the layout and/or operation of a knitting machine to provide the user with the impression of physically designing and/or manufacturing an article of footwear. In other embodiments, the system may disallow prospective footwear design changes based on limitations associated with inventory availability and the footwear design characteristics.

Pattern data for at least two sizes are converted to knit data, regarding knitted products to be graded. Regarding the knit data for at least two sizes, characteristic points specifying shapes of the knitted products and intermediate shapes specifying shapes of the knitted products between the characteristic points are generated. By interpolating or extrapolating the characteristic points and the intermediate shapes, according to a desired size of the knitted products, characteristic points and intermediate shapes for the desired size are generated. Closed loops are generated by connecting the characteristic points and the intermediate shapes, and knit data for the desired size is generated by allocating knitted stitches within patterns specified by the closed loops. Without pattern data for intermediate sizes, knit data for the intermediate sizes are generated from the two size knit data.

A method for modeling textile structures using bicontinuous surfaces includes selecting a virtual scaffold of bicontinuous surfaces defining textile fabrication pathways to model spatial relationships between the pathways and yarns in a desired yarn pattern of a textile fabric design. The method further includes constructing a yarn pathway across the bicontinuous surfaces that form the virtual scaffold. The method further includes removing or releasing tension from the virtual scaffold, thereby allowing yarns to relax and determining a physical property of the textile fabric design.
