The uppers are constructed from a Flyknit material in a single hue made to have a tight fit across the forefoot and the midfoot held together with a molded lacing system. There is then an additional synthetic around the heel to the quarter in a contrasting color. This also adds a base foundation to the white outlining of the Swoosh branding accent that informs the side of the shoe. It then sits on top of a slightly raised heel shank made from plastic.
