Featuring the same forward propulsion and plush cushioning as the Fusion 3.5, the special edition KARHU x SAYSKY Fusion 3.5 is a Nordic collaboration and celebration of the past, present and future. The two brands are joining forces to show that running is about community and moving forward in the same direction.
This swift and nimble shoe has been streamlined with a new upper and engineered for faster turnover. The Fusion features Karhu’s 3/4 length Fulcrum in the midsole that provides the quickest roll out of the Karhu shoe lineup. It concentrates the cushioning toward the heel and midfoot, creating a responsive rocker shape that stabilizes each step and propels you forward.
The plush and propulsive ride is also thanks to Karhu’s AeroFoam midsole, which is lightweight and more temperature resistant than the traditional EVA midsole foam. It provides super-soft landings, while an added propulsion unit energizes take-offs.
The new upper features a breathable engineered mesh that is designed with an intricate venting pattern and reinforced with glue print toe accents and a sleek heel counter. This new upper looks more stylish and feels more comfortable than ever.
The women’s version of the Fusion 3.5 features HeraFit, which is based on measurements from Fleet Feet’s 3D foot scans. From these scans, Karhu discovered that the instep and forefoot of men’s and women’s feet measured significantly differently. So Karhu adjusted the volume and circumference of the instep and forefoot to better fit women’s feet.
With the KARHU x SAYSKY Fusion 3.5, you will be rolling through your runs in style.
