Variable-density soles for articles of footwear and methods for constructing said soles are provided herein. In one embodiment, a variable-density sole for a footwear article comprises a first layer comprising a first density coupled to a bottom surface of an upper of the article of footwear; and a second layer comprising a second density greater than the density of the first layer, wherein the first layer is physically coupled to the second layer forming an interface between the layers. In this way, comfort of the article of footwear may be increased while decreasing the weight of the article of footwear. Further, forming the variable-density sole includes directly molding the first layer to a strobel board, stitching the strobel board to an upper, and injecting the second layer to the upper with the strobel board and the first layer. In this way, the production of a footwear article is simplified.
