A true neutral trainer with a plush and propulsive ride, the Fusion 3.5 features the quickest “roll” in Karhu’s running collection.
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 Fusion features a three-quarter length fulcrum.
Proprietary midsole foam: lighter, more resistant to temperature changes and better cushioning than EVA.
Seamlessly knitted upper patterns with zones for support, stretch, and breathability.
The M-lock side panels help secure the shoe around the foot while the inner construction remains straight.
