The Karhu Fusion 3.5 are all-round running shoes for the neutral runner. This shoe is a training shoe with a lot of cushioning that is also very suitable for up-tempo running. Compared to the previous version of the Fusion, the engineered mesh has an intricate ventilation pattern with a reinforced toe and updated heel counter. Lovers of the Fusion will love the new version for its comfort and consistent fit.
Due to the anatomical design, the laces provide better support. The upper follows the contours of your foot, making the shoe feel comfortable.
Karhu uses their Fulcrum technology. This technology is specially designed to move the forces released during walking forward and to reduce braking forces. The energy of the runner is converted into a forward movement, also called the "rolling effect". The Fusion 3.5 has the smallest Fulcrum technology block for faster forward energy return.
Don't shy away from a challenge with the latest Karhu Fusion 3.5
