The women's KARHU Fusion 3.5 is a highly responsive, cushioned running shoe for neutral footed runners. Whether going easy or pushing the pace, the forward propulsion and plush cushioning make your run comfortable and playful. The 6mm heel-toe offset, shortened Fulcrum, and propulsion unit result in a swift and nimble underfoot experience.
With every stride, the Fulcrum and propulsion unit will accelerate the transition from heel to toe-off, even during your easy runs.
The newly redesigned upper mesh is softer in the toe-box while the intricate venting pattern gives improved breathability. The Fusion 3.5 is an all-in-one shoe for the neutral runner with variety in their running workouts.

The women’s Fusion is built by women for women. By adjusting the circumference volume at the instep and forefoot, Karhu offers a personalized women’s construction: HeraFit.
