    The women's KARHU Fusion 4.0 provides a plush and propulsive ride ideal for the neutral runner. New additions and adjustments to the Fusion 4.0 make this shoe exceptional at seamlessly accelerating the transition from heel to toe-off, ensuring a responsive underfoot experience regardless of pace. This update utilizes soft IdealKnit mesh for improved breathability and comfort. Most notable is the incorporation of new nitrogen-injected AeroFoam in the midsole. This upgraded foam provides increased rebound, while the addition of a deflection channel at the bottom of the midsole helps absorb impact and provides a more cushioned experience.

    The KARHU Fusion 4.0 is the ultimate all-in-one shoe for runners seeking a unique blend of comfort, responsiveness, and performance.

    The women’s Fusion 4.0 is built by women for women. By adjusting the circumference volume at the instep and forefoot, Karhu offers a personalized women’s construction: HeraFit.
