KARHU x SAYSKY is a Nordic collaboration and celebration of the past, present and future. Almost a century apart in history. The industry legacy and the new kid on the block. From KARHU’s origin in 1916 to the launch of Saysky in 2013 – we’re now joining forces to show that running is about community and moving forward in the same direction.

The men's KARHU x SAYSKY 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.
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).

At KARHU, we know every runner has unique feet, and precisely that given resulted in the new Fusion. The Fusion 3.5 is built from a growing database of over 3 million 3D scans taken from runners' feet. The Karhu Fusion 3.5 is literally created by the runner, for the runner.
