A footwear article includes an upper assembly attached to a sole. The upper assembly includes an enclosure defining a foot receiving void and a flex feature disposed on a medial portion of the upper assembly. The flex feature connects a medial forefoot portion of the enclosure to a medial heel portion of the enclosure, thus allowing the medial forefoot and medial heel portions of the enclosure to move relative to each other. The sole assembly includes a midsole disposed on an outsole. The midsole defines voids of different depths. The voids are arranged to provide relatively greater cushioning and bendability within at least one of a metatarsus portion and a calcaneus portion of the midsole.
