The men's 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" as it 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.

Ich liebe Karhu Laufschuhe!

Ich trage schon seit über 15 Jahren Karhu Laufschuhe. Immer wieder kaufe ich auch von den Mitbewerbern, dennoch komme ich stets zu Karhu zurück. Preis-/Leistungsverhältnis sind in Ordnung, obwohl die Preise mittlerweile stark gestiegen sind.
