The women's KARHU Fusion 4.0 Vanilla Ice / Fiery Coral 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.
