The Synchron Classic features a new compression molded EVA midsole which is current in most modern running shoes. The dual density construction remains true to the original version from the early 1990's. The upper materials have been improved to the premium pigskin suede from synthetic overlays while the original mesh appearance remains true to the era. To modernise the silhouette, Karhu makes the air cushion technology both visible and functional in the outsole. Most importantly, Karhu keeps the unique Synchron Classic lacing structure which served as a way to tighten the forefoot upon repeated use.

The Synchron made its first appearance in 1980, introducing a unique lacing system in the toebox that set this shoe apart from other footwear. The innovative design aimed to provide a better fitting upper for added comfort and durability. The Synchron Classic 90s edition features an air cushion unit and a stable heel cap to ensure a supportive and comfortable experience with every step.
