Sizing: The Synchron style fits small. We recommend going a half size up from your usual fit in this shoe. IE, if you usually wear a women's 8.5, we'd suggest a women's 9 in this style.
The Synchron style first made its debut in 1980. As the assortment got bigger over the years, it became easy to recognize the group by the unorthodox lacing system in the toebox. The design team wanted to provide a better fitting upper and came up with the innovative lacing system for added comfort and durability. The Synchron Classic, the 90s edition within the Synchron category, remains a comfortable model featuring an air cushion unit and a stable heel cap.
