Footwear midsole with warped lattice structure and method of making the same

A method of making a sole for an article of footwear, the method comprising:

• generating a lattice structure, the lattice structure:
• defining a volume of at least a portion of a midsole for the sole, comprising a plurality of lattice cells, and defining a plurality of nodes;
• populating each one of the plurality of lattice cells with a lattice unit cell, the lattice unit cells defining a cell lattice comprising the lattice unit cells connected to each other at one or more of the nodes, and the lattice unit cells comprising a first plurality of lattice unit cells comprising a first base geometry and a second plurality of lattice unit cells comprising a second base geometry different than the first base geometry;
• and
• forming a three-dimensional mesh for the midsole, the three-dimensional mesh comprising a plurality of interconnected unit cells, wherein a first plurality of the interconnected unit cells each comprise a plurality of struts defining a three-dimensional shape corresponding to the first base geometry, and wherein a second plurality of the interconnected unit cells each comprise a plurality of struts defining a three-dimensional shape corresponding to the second base geometry.
