In alternative embodiments, the anterior-most portion 80 is biased medially or laterally.

In some embodiments, the shoe 20 includes a chassis member 26 and/or a heel counter 82. The chassis member 26 is coupled to the outsole 22 and is longitudinally and laterally coextensive with the outsole 22. The chassis member 26 includes a heel portion 84 that extends over a portion of the heel counter 82. Heel counter 82 extends over a portion of heel region 36 of the knit upper. Heel portion 84 of chassis member 26 and heel counter 82 are adapted and configured to stiffen the upper in heel region 36 of the knit upper. For example, but not limiting of, heel counter 82 is constructed of leather and increases stiffness in heel region 36. The chassis member 26 may be made of any suitable material, such as leather, thermoplastic polyurethane, and the like.

Knit element 32 can be knitted with one or more yarns, such as polyester yarns, nylon yarns, cotton yarns, and spandex yarns. In one embodiment, knit element 32 is knit from polyester covered spandex yarn and hot melt yarn such that in the finished knit element, the polyester covered spandex yarn constitutes at least 50% (by mass) (and more preferably at least 60% (by mass)) and the hot melt yarn constitutes at least 15% (by mass) (and more preferably at least 20% (by mass), but not more than 30% (by mass)). The hot melt yarn is knitted with the polyester covered spandex yarn during the knitting process. Preferably, the polyester covered spandex yarn has a linear density between about 120 denier and about 180 denier and the hot melt yarn has a linear density between about 80 denier and about 120 denier. In addition to the polyester covered spandex yarn and the hot melt yarn, knit element 20 can be knit with an elastic yarn, wherein the elastic yarn preferably constitutes at least 5% (by mass) of the knit upper. If included, the stretch yarn is preferably, but not necessarily, limited to the top line area of knit element 32 to provide stretch function primarily in the ankle area of upper 24 of footwear 20. Preferably, the polyester-covered spandex yarn comprises a double layer of polyester. Also preferably, the stretch yarn is a spandex yarn. In another embodiment, knit element 32 is formed by knitting a hot melt yarn with a polyester yarn during the knitting process such that the polyester yarn constitutes at least 50% (by mass) of the knit element and the hot melt yarn constitutes at least 15% (by mass) of the knit element.

A method of constructing footwear 20 includes knitting upper 24 to include knit element 32 as described herein. For example, but not limiting of, the upper 24 may be knitted using a knitting machine, such as a CNC knitting machine. Subsequently, knitted upper 24 may be placed around a last and heated so that the upper assumes the shape of the last. The heat secures the hot melt yarn to the second yarn or the type described herein. Heel counter 82 is coupled to upper 24 by stitching, adhesive, or threads. The chassis member 26 is coupled to the upper 24 using stitching, adhesives, or the like. The chassis member 26 covers the heel counter 82.
