The women's Karhu Synchron is a premium cushion daily trainer for runners who are neutral or mid to late-stage overpronators. The Synchron gives you a soft and stable ride with a smooth, supportive transition.
The Karhu Synchron utilizes advanced midsole materials to offer the softest running experience in the Karhu collection. The redesigned internal Fulcrum unit is more flexible than before which accentuates the cushion and improves the transition. The adjusted upper moves easily with the foot and accommodate a broader range of foot shapes. Newly added is the open-cell foam insole for a plush feel.
