The women'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 women's Fusion is lighter than previous versions and maintains a touch of rearfoot support while providing an even quicker transition. The women’s Fusion in 2021 is the first shoe built by women for women. By adjusting the circumference volume at the instep and forefoot, Karhu offers a personalized women’s construction we call HeraFit.

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 Fusion Ortix 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.

These shoes are a second pair for my teenage cross country runner. She loved her first pair so much that she wanted to go ahead and get another pair lined up.

Best Shoe

My doctor told me to get better support shoes for my planters fasciitis. I went to Fleet feet and they brought out the hokas and Karhu. I tried both and liked the Karhu better. They were not as bulky as the Hokas and still had great support I love them
