The Nike Air Flow is an iconic shoe, conceptualized by Air Force 1 designer Bruce Kilgore and launched over 20 years ago (in 1989) in a neon colorway. Since then, brightly colored, running-inspired sneakers have become a norm in the footwear world. Nonetheless, the official announcement of the Nike Air Flow Old vs. New Pack is an exciting one. Encompassing two colorways – the classic electric green/neon blue as well as a lush teal/varsity purple – the Old vs. New Pack was designed by Nike to serve as a testament to the influence the Air Flow has had in terms of sneaker design over the past two decades. This ’80s-era pack will be available June 25 at select Nike dealers.
