The Karhu Synchron Classic is a 90s iteration of the original Synchron line, which first launched in 1980. The Synchron series is distinguished by its unique toebox lacing system, designed by Karhu's research and development team to enhance fit, comfort, and durability. This updated classic model retains the comfort-focused design, incorporating an air cushion unit and a supportive heel cap.
