Abstract:

A knitted component may form at least a portion of an article of footwear. For example, a first knit layer may be located on an inner side of an article of footwear such that the first layer is adjacent to a void, and a second layer may at least partially surround the first layer and form an outer surface of the article of footwear. An interstitial space may be formed between the first layer and the second layer. At least one pocket may be located within the interstitial space.
