About this product
Nike offers another edition in their Free series with the Free Flyknit 4.0, which reinvents the sock-like fit of the Flyknit upper to improve ventilation and stability. This lightweight runner sports a simple black and white color scheme in a series of designs, including dotted detailing on the side panels and toe. The black midsole sits atop a white Free outsole, which is anatomically shaped with adaptable flex grooves for cushioning and traction.
