About this product
Nike's Free 4.0 Flyknit deconstructs the idea of a traditional running shoe through minimalist design principles and adaptive technology. Taking on a full tonal look, this iteration is equipped with a breathable sock-like bootie, a molded sock liner and a Flywire lacing system for customizable security. Simple branding is fused to the tongue. Its contrast Phylite midsole carries hexagonal flex grooves and grippy waffle outsole.
