    My compliments

    Finally, I can appreciate these running shoes - I ran over 400km with them.
    I haven't had better shoes in the last 35 years :-) I'd be happy to order another pair of the same. I am very grateful to be together.

    Solid shoes for long miles

    Amazing design. The toe box has a good amount of space. Feels soft and supportive for long runs, solid neutral trainers! A bit heavy weight tough but you need to give up something for the support.

    My new Karhu Synchron 2021

    Very comfortable, but a little heavy. I believe I will get used to it very soon.
    Good luck and thank you very much

    TECHNOLOGY

    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 whe call the Rolling Effect. Fulcrum Technology provides: Balanced Cushioning, Increased Support, More Energy. The Ikoni has a half-length fulcrum for flexible forefoot.

    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.

    Seamlessly knitted upper patterns placed on the Ortix lasts with zones for support, stretch, and breathability.

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