Karhu Fusion HiVo Men

The Karhu Fusion HiVo for men are neutral, all-round running shoes. This shoe is a training shoe with a lot of cushioning that is also very suitable for up-tempo running. The Fusion comes with a High volume (HiVo) fit. This fit gives more room in the forefoot. Karhu looked at the difference between men and women when making the Fusion 21. For example, their foot scans showed that the circumference of the instep and forefoot is narrower in women than in men. They have adjusted this compared to the old model.

By analyzing the scan data, Karhu has developed an all-new upper to improve fit and performance. The upper consists of seamless Ideal Knit mesh, which also makes the shoe very breathable. Due to the anatomical design, the laces provide better support. The upper follows the contours of your foot, making the shoe feel comfortable.

To reduce the weight in the shoe, the overlays in the upper have been removed, but the good fit remains. The power of the shoe is mainly in the take-off and the quick settlement. The energy return is converted into a forward movement.

Karhu uses their Fulcrum technology. This technology is specially designed to move forward the forces released during walking and reduce braking forces. The runner's energy is converted into a forward movement, also known as the "rolling effect". The Fusion 21 has the smallest Fulcrum technology block for faster forward energy return.
