1. A method of making a sole for an article of footwear, the method comprising:
generating a warped cubic lattice structure based on a biometric data profile collected for an individual, the warped cubic lattice structure: defining a volume of a midsole for the sole, comprising a plurality of cubic lattice cells having different volumes and cubic geometries, and defining a plurality of nodes;
populating each one of the plurality of cubic lattice cells with one-two or more individual partial lattice unit cells based on the biometric data profile, the two or more individual partial lattice unit cells defining complete lattice unit cells of forming-a cell lattice comprising the complete lattice unit cells connected to each other at one or more of the nodes;
printing a midsole comprising a three-dimensional mesh based on the biometric data profile, the three-dimensional mesh comprising a plurality of interconnected unit cells, each one of a plurality of the unit cells comprising a plurality of struts defining a three-dimensional shape corresponding to the shape of a respective complete lattice unit cell; and
printing an outsole with the midsole, the outsole comprising a portion defining a ground contacting surface of the sole, and a portion defining a perimeter side portion of the sole,
wherein the perimeter side portion of the sole defined by the outsole is formed over and covers two or more of the plurality of the interconnected unit cells at the perimeter side portion.
