Jack shoes mean Jack purcell. JackPurcell is one of the main sub-brands of converse, a world-renowned first-line brand of canvas shoes. Because this series originated from the world badminton champion JACKPURCELL in 1930s, its English name is ConverseJackPurcell series. The biggest feature of this series is the symbolic smile arc logo on the toe and the autograph of JackPurcell behind the heel.
