Midsole

Karhu's AeroFoam is used to make the midsole of this shoe. This material is lighter, more resistant to temperature fluctuations, and more durable than traditional EVA foam. With the help of Fulcrum technology in the midsole, this shoe moves forward through a balanced cushioning, thereby offering more support. The propulsion plate will provide you with extra stability while running and, moreover, the plate propels you forward.
