Description

The men’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 Synchron 2021 utilizes advanced midsole materials to offer the softest 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.

The KARHU Fulcrum technology is designed to keep all forces going forward, reducing braking forces and using your body’s natural energy to create a smoother ride. It’s what we call the Rolling Effect. Fulcrum Technology provides: Balanced Cushioning, Increased Support, More Energy. The Synchron features a full length stingray fulcrum.
