BUILT BY WOMEN, FOR WOMEN: The women's Fusion is the first shoe built by women for women. By adjusting the circumference at the instep volume and forefoot volume, Karhu offers a more personalized women's construction we call HeraFit.
DAILY RUNNING SHOE: Get something you can use every day. The women's Karhu Fusion is an all-in-one, highly responsive, cushioned shoe for the neutral runner with variety in their running workouts.
PLUSH BUT PROPULSIVE: Highly cushioned AeroFoam midsole provides a plush yet propulsive ride. It's ideal for performance-oriented athletes seeking a shoe for up-tempo workouts or race day.
DESIGNED TO MOVE YOU FORWARD: A 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.
COMFORTABLE SECURE FIT: Includes Ideal Knit woven upper for support, stretch, and breathability, and M-Lock lacing construction for a secure midfoot.
