A segmented crash pad works in unison with the cushioning system to smooth the transition from heel to toe, running shoe insole.
The KARHU Fusion 4.0 HiVo 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 HiVo version is more than just a "wide fit" as it also accounts for feet with higher insteps, greater instep girths, flat, and all-around larger-than-average feet.
The KARHU Fusion 4.0 is the ultimate all-in-one shoe for runners seeking a unique blend of comfort, responsiveness, and performance.
