Article of footwear having a knit upper with a polymer layer

摘要

An article of footwear has an upper and a sole structure secured to the upper. The upper includes a knitted component and a polymer layer. The knitted component is formed of unitary knit construction and extends along a lateral side of the upper, along a medial side of the upper, over a forefoot region of the upper, and around a heel region of the upper. The polymer layer is bonded to the knitted component and may form a majority of an exterior surface of the upper. The polymer layer may be formed from a thermoplastic polymer material.

1. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising:
a knitted component formed of unitary knit construction, the knitted component including a tubular structure, the tubular structure comprising a first knitted layer and a second knitted layer that are overlapping and joined along opposite edges to form an unsecured central area of the tubular structure; a strand having a configuration of a one-dimensional material, the strand extending through at least a portion of a length of the unsecured central area of the tubular structure; a polymer layer bonded to the knitted component and forming a majority of an exterior surface of the upper; and wherein the polymer layer infiltrates and bonds to the first knitted layer of the tubular structure and remains unsecured to the second knitted layer of the tubular structure.
