Features

Be ready for an uptempo run in the KARHU Fusion 3.5.

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 Fusion 3.5, you will be rolling through your runs.

Perfect for orthotics

The KARHU is like Hoka - incredibly supportive and cushioned, with an ample toe box, and it hugs my narrow heel. But my new orthotics needed a wider shoe, so the nice people at Fleet Feet suggested the KARHU, a brand I’d never heard of. It’s a 100 year old European brand (my daughter who lives in Europe confirmed these are seen all over), and it saved my feet. I like how easy it is to adjust the width, as I have a narrow heel and arches, but my orthotics spread out the arch and toe box. These come up high enough and are so adjustable that my feet rest comfortably in the sole, but the fit is snug around the top of the foot. And I can walk for miles. I’m not a runner, so I can’t comment on that, but I have already bought a second pair because I like them so much.
