The Nike Daybreak Undercover Black Sail features a black nylon and suede upper with a deep black look that is only broken up by different shades of the same color. A Sail white midsole featuring 'Jun Takahashi Undercover' lettering and a white tongue tag with Nike lettering complete the design. Nike collaborated with Japanese designer Jun Takahashi to create the Undercover x Wmns Daybreak 'Black Sail,' a futuristic take on a classic runner from the late 70s. This concept shoe, released in June 2019, incorporates unconventional details such as a sharp, speckled heel clip that angles up to the back of the collar for dramatic effect.
