Designed for runners looking for a smooth, energetic ride, the KARHU Fusion 5.0 is the new generation of the trusted neutral training shoe.

A repositioned Fulcrum unit guides your foot efficiently with every stride, creating a more propulsive ride. Combined with increased toe spring, the Fusion running shoe delivers a responsive toe-off with more momentum and energy return. The midsole features the brand-new AeroFoam NOVA, which allows a higher stack and a softer, more cushioned ride with improved bounce. A high-quality foam sockliner provides lasting underfoot comfort that holds its performance over time.

Designed for a balanced fit, the Fusion 5.0 offers a secure midfoot lockdown while leaving plenty of room in the toe box, for a comfortable ride on every occasion, from daily training to your higher-mileage days.
