From Karhu

Experience the unique blend of comfort, responsiveness, and performance with the Women's Karhu Fusion 4.0.

The AeroFoam midsole, now nitrogen-infused, provides the right balance of cushion and responsiveness. The midsole has an increased rebound, with the addition of a deflection channel that helps to absorb impact. The IdealKnit upper has been updated for a more breathability and comfort.

A shoe designed by women for women, the women's Fusion 4.0 encompasses HeraFit, a personalised women's construction of the circumference volume adjustment at the instep and forefoot.

Shortened Fulcrum + Propulsion unit for an efficient stride.
