a bladder including a barrier layer defining an interior void; and
a compressible component disposed within the interior void and including a foam lattice structure defining a plurality of reliefs formed in the lattice structure, a first plurality of the reliefs operable to contract in a first direction in a forefoot region of the upper and a second plurality of the reliefs operable to contract in a second direction in a mid-foot region of the upper, wherein the compressible component operates between an expanded state when the interior void includes a first pressure and a contracted state when the interior void includes a second pressure less than ambient pressure.
