Abstract
A chassis for an article of footwear may include a base and a frame attached to a top side of the base. The frame may include a network of interconnected walls defining a plurality of cells, each of at least a portion of the cells having a bottom at least partially closed by an underlying portion of the base. A bottom of the base may be fixed with respect to a plantar section of an upper. A sock liner may be indexed to the chassis or to another footwear support structure. The sock liner may have downwardly-extending tabs configured to rest in cells of the chassis or in other cavities of a support structure.
