1. An upper for an article of footwear, the upper comprising:
a first knit layer;
a second knit layer;
a third layer formed as a membrane located between the first knit layer and the second knit layer, the third layer including a thermoplastic polymer material with a melting point of 150° C. or less, wherein the first knit layer and the second knit layer are secured via the thermoplastic polymer material of the third layer;
a first zone, wherein the first knit layer, the second knit layer, and the third layer are coextensive in the first zone; and
a second zone, wherein the first knit layer, the second knit layer, and the third layer are coextensive in the second zone, and wherein less of the material of the third layer, by mass per unit surface area, is located in the second zone than in the first zone,
wherein the first zone has a first stretch resistance, wherein the second zone has a second stretch resistance, and wherein the first stretch resistance is greater than the second stretch resistance.
