• The Nike Free Flyknit Chukka has been a popular silhouette ever since the rise of Nike’s Flyknit uppers. For Spring 2015 the sneaker returns in a new midnight fog colorway. The sneaker’s dark upper sits on a contrasting white Free outer-sole. Bright magenta accents on the knitted upper and the heel tab act as a nice contrast, adding some flavor to the otherwise subtle upper. You can buy the new Nike Free Flyknit Chukka “Midnight Fog” now from select retailers, including Overkill.
