The men's Karhu Fusion is a high cushion running shoe for neutral footed runners. With a plush yet propulsive ride, it's ideal for performance-oriented athletes seeking a shoe for up-tempo workouts or race day.

The new men's Fusion is lighter than previous versions and maintains a touch of rearfoot support while providing an even quicker transition. The renewed upper reduced weight while keep delivering a secure fit. The Fusion now features a shortened Fulcrum, the shortest in the collection, and a propulsion unit for an even faster feel. Lastly, extra cushioning is added to the forefoot for more protection at toe-off.

At Karhu, we know every runner has unique feet and precisely that given resulted in the new Fusion. The Karhu Fusion is built from a growing database of over 3 million 3D scans taken from runners’ feet. The Karhu Fusion is literally created by the runner, for the runner.
