1. An article of footwear comprising:
a midsole including,
a unitary lattice structure including an upper side and a lower side, wherein the upper side is a user-facing side and the lower side is a ground-facing side, the lattice structure comprising a network of wave structures arranged multiple transverse layers, wherein peaks of the wave structures in one layer are joined to valleys in the wave structures of an adjacent layer; and
an upper rim integrally formed with the unitary lattice structure, the upper rim extending around an upper perimeter defined on the upper side of the lattice structure;
an upper disposed above the midsole; and
an outsole disposed below the midsole.
