The women's KARHU Fusion 4.0 HiVo Sea Foam / Excalibur 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" 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.

Good quality but runs small

I purchased a 9.5 size running shoe which is a half size larger than my usual size. They are much too tight in width and length even after trying to break them in. The quality of the shoe is great but I’d recommend going a full size bigger.

Love my KARHUs!

I’ve got two pairs. One for gym, the other for every day wear. So comfortable and provide great support for my feet.
