Per Nike: Remembering the first born of the Nike Free line — the Nike Free 5.0 — the Nike Free OG replicates its silhouette and provides updates for a modern look and feel. A traditional tongue replaces the original bootie for a wider range of fit and increased comfort, while an updated Nike Free outsole specific to Nike Sportswear lends a contemporary, sleek aesthetic. The original synthetic suede, perforated upper and dynamic heel pocket are carried over, completing the 10-year celebration of Nike Free.
