Discover the Men’s Fusion 5.0 in Blanc de Blanc / Ultramarine Green, a special edition of our latest silhouette, celebrating the 30th anniversary of the original Fusion running shoe from 1996. The brand-new Fusion 5.0 combines the Fusion OG colourway with the latest running innovation for a smooth, energetic ride.  

The updated Fusion 5.0 is designed for runners seeking a blend of cushioning and performance. It features a 6mm heel-toe offset, a more robust foam package, a refined fit, and a redesigned Fulcrum for a silky-smooth experience. Ideal for long runs and faster workouts.

Built for runners seeking a smooth and energetic ride, the KARHU Fusion 5.0 introduces the next generation of KARHU running technology.

A repositioned Fulcrum unit guides the foot efficiently through each stride, creating a more propulsive running experience. Combined with an amplified toe spring, the Fusion 5.0 delivers a responsive toe-off with added momentum and energy return. The midsole features all-new AeroFoam NOVA, allowing for a higher stack height and a softer, more cushioned ride with improved rebound. A critical foam insole provides durable underfoot comfort that maintains its performance over time.

Designed for a balanced fit, the Fusion 5.0 offers a secure midfoot lockdown while maintaining ample room in the toe box, creating a comfortable running experience for everything from daily training to longer mileage days.
