The KARHU Fulcrum technology is designed to keep all forces going forward, reducing braking forces and using your body's natural energy to create a smoother ride. It's what we call the Rolling Effect. Fulcrum Technology provides: Balanced Cushioning, Increased Support, More Energy. The Fusion features a three-quarter length fulcrum.


OrtixFit shapes your mid sole and upper volumes using data directly collected from over 2 Million runner's feet. What started in 2018 with the launch of the Karhu Ikoni the 1st model shaped by ORTIX, we now offer all our footwear models with our ORTIX Fit, based on actual scanning data in regular, HiVo (more volume) and Hera (women specific) Fit volumes. Karhu collaborates with Volumental(TM) and Fleet Feet(TM) create personalized fit experiences.


Our proprietary midsole foam: lighter, more resistant to temperature changes and better cushioning than EVA.


The M-lock side panels help secure the shoe around the foot while an inner booty construction remains straight.
