Karhu shoes are all about comfort and a good fit. That is why Ortix Fit was developed. The Ortix Fit refers to the geometry of the midsole, the volume of the upper and the overall dimensions of the shoe. To create his Ortix Fit, Karhu analyzed no fewer than 3 million foot scans. Then HiVo, the ideal shoe for men, and HeraFit, the ideal shoe for women, were developed.
Midsole
The midsole of this shoe is made of AeroFoam. This material, patented by Karhu, is lighter, more resistant to extreme temperature changes and more durable than traditional EVA foam. A midsole with Fulcrum technology and a propulsion plate provides a balanced cushion, more support and more energy when pushing off.
Upper
The Fusion features an Ideal Knit mesh upper. The upper feels pleasant and has great breathability. The M-lock system, together with the reinforced heel cap, ensures good lockdown of the foot. This ensures that your foot does not slide. The shoe is also equipped with a toe protector, which provides an extra layer of protection for your toes.
Outsole
With a rubber outsole, the shoe provides good grip and traction while running. Put on your Karhu Fusion 3.5 shoes and prepare to push your limits!
