Fashion designer Riccardo Tisci collaborated with NikeLab to create a Triple Black version of the Free Train Force Flyknit, which was launched in July 2016 as part of the 'Training Redefined' collection. The mid-top sneaker features a breathable Flyknit upper and a Nike Free sole unit that imitates the movement of a bare foot. Its sleek all-black design is enhanced with a touch of blue through the RT and Nike Swoosh branding on the heel loop.
