The men's KARHU Fusion 3.5 is a highly responsive, cushioned running shoe for neutral footed runners. Whether going easy or pushing the pace, the forward propulsion and plush cushioning make your run comfortable and playful. The 6mm heel-toe offset, shortened Fulcrum, and propulsion unit result in a swift and nimble underfoot experience. With every stride, the Fulcrum and propulsion unit will accelerate the transition from heel to toe-off, even during your easy runs. The newly redesigned upper mesh is softer in the toe-box while the intricate venting pattern gives improved breathability. The Fusion 3.5 is an all-in-one shoe for the neutral runner with variety in their running workouts.

The Fusion 3.5 is also available in a wide fit, KARHU calls this High Volume (HiVo).

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.
