In the market for new gym shoes? Nike recently called on the help of Stanford University athletes to design the perfect running shoes. Combining the comfort of Nike‘s ‘Free’ technology with the brand’s lightweight ‘Flyknit‘ construction, the Free 4.0 Flyknit Sneakers mimic the shape of the foot to promote a more natural footstrike. The latest release from this range comes in a black and grey colorway that features a white swoosh emblem on the side. Complete with cushioned Phylon midsoles, lightly padded ankles, and gripped rubber soles; check out images below: Interested? You can purchase the shoes for $120 by clicking here.
