DAILY RUNNING SHOE: The Karhu Synchron 2.0 is a premium cushioned daily running shoe designed for neutral to late-stage overpronators and long-distance runners. It offers enhanced breathability with an improved IdealKnit mesh upper and an asymmetrical toebox lace. SIZE RECOMMENDATION: For the best fit, we recommend sizing up a full size compared to your regular size. COMFORT & STABILITY: Experience a lighter and softer run with the AeroFoam Nova midsole, providing exceptional shock absorption and durability. The redesigned Stingray Fulcrum and full-contact rubber outsole deliver outstanding support and stability, perfect for long runs. HIVO: Available in both medium width and HiVo (Wide). More than just “wide,” HiVo provides a higher volume upper to accommodate thicker or broader feet, and feet with common problems like bunions, calluses and corns. A premium cushioned daily trainer with a soft and stable ride, the all-new Synchron 2.0 receives a complete “heel-to- toe” update for the SS23 season. As always, the Synchron serves up the steadiest “roll” in our running collection, but a repositioning of the Stingray Fulcrum combined with a lighter, softer blend of AeroFoam Nova produces a more flexible, runnable midsole. With an underfoot that’s engineered to protect and support, the Synchron is ideal for long days and longer runs. its soft and stable ride.
